                        Chapter 1 ― General Information


1.1     Introduction
This section provides an overview of the National Airspace System (NAS) and Traffic
Management Advisor (TMA) concept of operations.


1.2     NAS Overview
TMA is one of a number of computer-based systems that comprise the NAS. The TMA tool
operates within the en route domain.

The en route domain includes 21 Air Route Traffic Control Centers (ARTCCs). Twenty are
located in the Continental United States (CONUS) and one is located in Alaska. Each ARTCC
includes a Host Computer System (HCS) that keeps track of flight plans for the traffic in those
sectors comprising the ARTCC. The ARTCC HCS also receives near real-time live radar reports.
These radar reports indicate the position of all airborne traffic detected in the ARTCC airspace.
The HCS processes the ARTCC data and displays sector boundaries and sector traffic on
individual displays. Air Traffic Controllers use this display information to control air traffic in
their respective sector(s). As airplanes traverse the airspace boundary between adjacent sectors
within an ARTCC and between ARTCCs, a controller handoff occurs.

The terminal domain includes Terminal Radar Approach Control (TRACON) facilities. As
aircraft traverse a sector boundary between an ARTCC and TRACON a controller handoff
occurs. The ARTCC HCS also interfaces with the TRACON's Automated Radar Terminal
System (ARTS) or Standard Terminal Automation Replacement System (STARS). The ARTS or
STARS computer processes flight plans and aircraft radar reports and display sector
information on the TRACON displays. TRACON controllers use this information to control
airspace traffic in their respective sectors.


1.3     TMA Overview
TMA calculates en route arrival schedules to major adapted airports and schedules for en route
departures and overflights. TMA calculates Estimated Times of Arrival (ETAs) for aircraft, and
then applies airport and airspace constraints by Traffic Managers to compute Scheduled Times
of Arrival (STAs). The difference between the ETA and STA is the aircraft’s delay. This delay is
displayed to the en route arrival and departure sector controllers in aircraft arrival sequence
lists for crossing a meter fix into an airport or a meter point exiting an ARTCC that enable them
to implement the arrival traffic plan. TMA also provides traffic management planning and
statistical recording capabilities in ARTCC and TRACON Traffic Management Units (TMUs),
and can drive situation displays for use in airport towers. TMA Build 2 replaces TMA Build 1
hardware and software previously deployed in four ARTCCs and is deployed at all 20 ARTCCs.

November 2009                                                                      General Information


1.4     TMA Operational Capability Overview
TMA is a set of computer processes that rapidly generates a time-ordered sequence list and
presents it on the TMA Timeline and Planview Graphical User Interface (GUI), and on the
Center controllers’ Display System Replacement (DSR) displays (see Figure 1-1). The sequence
list consists of the following:

            Aircraft Identifier (ACID)
            Scheduled meter fix and outer metering arc crossing times
            Projected delay for each aircraft




                       Figure 1-1. Controller DSR With TMA Advisories Displayed


The sequence list is in the center of the portion of the DSR screen shown in Figure 1-1.

TMA calculates and updates ETAs to the meter fixes, all eligible runways and meter points
based on radar track or flight plan data. In calculating ETAs, TMA analyzes the possible routes
and trajectories that an aircraft is likely to take based on factors such as assigned meter fix,
destination airport, airport configuration, engine type and approach segment, and the aircraft’s
current position, altitude, heading, and speed.




                                                 1-2
TMA Reference Manual                                                              CSC/TMA-09/0104
November 2009                                                                     General Information


The TMA scheduler combines this information with other scheduling constraints to calculate an
STA to a Meter Fix (MFX) and/or runway and Meter Point (MP) for each arriving aircraft and
to a Meter Point for departing and overflight aircraft. Scheduling constraints may apply to
meter points, meter fixes, runways, flow rates, or other requirements. The goal is to ensure that
any demand in excess of an airport’s and/or the TRACON’s or ARTCC’s capacity is safely and
efficiently absorbed throughout the airspace. As mentioned, the difference between an aircraft’s
STA and ETA represents the projected delay (or advance) for that aircraft.

TMA provides information by way of two graphical user interfaces that the Traffic Management
Coordinators (TMCs) can use as an aid in strategic and tactical arrival planning:

The Timeline Graphic User Interface (TGUI). This interface uses timelines to display the STAs
and ETAs of each aircraft. It also can produce load graphs that display the number of aircraft
crossing selected reference points in a given period based on ETAs or STAs.

The Planview Graphical User Interface (PGUI). The PGUI presents a map-oriented view of
arriving aircraft.


1.4.1       Timeline Graphical User Interface
The TGUI (Figure 1-2) provides a time-based perspective on arriving traffic that complements
the map-based view of the PGUI. TGUI features include:

               Timeline displays that facilitate visualizing the traffic approaching specified
                reference points (that is, fixes/arcs and runway thresholds).
               The ability to view the scheduled delay for individual aircraft. When timeline
                sides are set to show ETA/STA comparison, aircraft delay, and advance
                conditions are more visually apparent.
               The ability to make scheduling changes for single aircraft or groups of aircraft
                using the TGUI Status and Schedule features.
               The ability to visualize in advance the impact of possible changes in airport
                configurations (for example, north flow to south flow), acceptance rates, or other
                scheduling constraints.
               Load graph displays that show the amount of traffic scheduled to cross specified
                reference points in a given period.
               The ability to produce printed delay reports.

1.4.2       Planview Graphical User Interface
The TMA PGUI display (Figure 1-3) provides a spatial display of individual aircraft track
information. The PGUI is composed of several dynamic features, most of which can be
manipulated or customized using a mouse-controlled pointer, quick keys, shortcut keys, and/or
function keys. Some of the features include:

               Predefined TRACON and ARTCC airspace radar maps (automatic display)
               Aircraft symbols (automatic display)
               Datablocks (optional)
               Universal Coordinated Time (UTC) clock (optional)
               Scratch pad/message area (optional)
               Range rings (optional)

In addition to the map display, the PGUI can show an optional Sequence List, which is a tabular
display of information about arriving aircraft sorted by the scheduled order of arrival at the
meter fixes or meter points.

                          Chapter 2 ― TGUI Functionality


2.1     Introduction
The TMA TGUI provides TMCs with graphically displayed views of TMA traffic flow
information and a means to interact with and change the traffic flows.

The TGUI software process uses message inputs originating from other TMA Computer
Software Configuration Items (CSCIs) and translates them into graphical information displayed
at a TGUI workstation display. The displayed information enables the TMCs to interpret traffic
flow for their specific facility’s geographic points of interest. It uses ETAs and TMA STAs for
schedulable aircraft, which arrive at specified fixes and runway thresholds associated with
designated TMA adapted ARTCC, TRACONs, and airport airspace areas.

The TGUI process also enables the TMCs to control scheduling constraints and to modify
aircraft flight schedules. They can initiate TMA command messages such as scheduling
constraints, airport configuration changes, and aircraft arrival times by way of keyboard entries,
mouse entries, and graphical object and menu selections. These command inputs affect the
other CSCI processes, which in turn provide feedback to the TGUI. TMC change actions affect
TMA outputs such as aircraft sequence, and runway advisories received by controllers
providing air traffic separation and control.

The TGUI software is compatible with National Aeronautical and Space Administration
(NASA) versions and incorporates lessons learned from Build 1, while implementing new
Computer-Human Interface (CHI) requirements. It uses Open Software Foundation (OSF) Motif
with X windows in graphic presentations, though certain presentations are nonstandard. A Sun
processor with a Solaris operating system in the UNIX environment hosts the TGUI.

Other Spiral 2 improvements add TGUI capabilities dealing with departures internal to the
ARTCC boundaries, deconfliction of aircraft within TRACON boundaries, the ability to use
TMA meter fixes (including meter fix arcs corresponding to TRACON boundaries), the ability
to utilize the Common Message Set (CMS), and incorporation of simulation capability. These
enhancements do not change the basic functionality of the TGUI as detailed in the following
paragraphs.


2.2     Functional Overview
For the TMCs, the TGUI process has three primary functions:

        1.      To draw timeline and/or loadgraph-related information in the TGUI monitor
        2.      To request specific additional information for the display




                                                2-1
TMA Reference Manual                                                                              CSC/TMA-09/0104
November 2009                                                                                     TGUI Functionality


          3.      To input changes affecting the STA of aircraft en route to adapted airports and
                  changes affecting the configuration of planned fixes and runways in the airspace
                  for arrival aircraft


2.3       Functional Descriptions
The following paragraphs provide a description of the windows, dialog boxes, and central pull-
down menus used in the TGUI. Each discussion provides the name, a short
definition/description of the window/dialog box/menu, a discussion of when to use the
function, and a general note on how to access the feature.


2.3.1 Aircraft Data Window
Definition – The aircraft data window provides a summary of the flight plan for a selected
aircraft. This information is expandable to include arrival times and departure data for internal
departures. Delays in the filed route of flight and in the adapted coded routes in the filed plan
are shown if they exist.

When to Use this Function – To access more in-depth information on a flight

How to Access – There are four ways:

              Double click on an aircraft tag on an arrival timeline (data filled in)
              Enter Control+A (brings up a blank window)
              From the Browse Aircraft panel
              From the Display menu on the Status and Schedule window


This window may be set to automatically close after a site-adapted period of time. The system
can be adapted to have the Schedule a Departure dialog open when an internal departure is
double clicked on specified sides of the arrival timelines. In that case, the other methods of
opening the window will need to be used.


                        Table 2-1. Key Things To Know for the Aircraft Data Window

          Field                                                Notes
      Flight ID        Accepts user entries to search. Entries may be any valid flight ID, or a blocked slot
                       tag ID. An error message is displayed if no matching entry is found in the system. If
                       multiple aircraft exist with the same flight ID, a selection panel pops up with
                       additional information so that the user can select the current aircraft.




2.3.2          Airport Acceptance Rate (AAR)
Definition –The limit on the number of arrivals per hour at an adapted airport. Unrestricted
Rate (UR) can be set for the TMA Scheduler to apply the minimal separation between aircraft


                                                         2-2
TMA Reference Manual                                                                CSC/TMA-09/0104
November 2009                                                                       TGUI Functionality


based on aircraft weight category. In addition, each runway has its acceptance rate or can also
be set to UR.

When to Use this Function – Used to set a value as to how many aircraft a TRACON at an
adapted airport can handle per hour based on airport conditions, that is, number of runways
available, turnoffs, taxiways, weather conditions, staffing, and so on.

How to Access – From the Status and Schedule window, QuickSet, or Configuration and
Runway Settings.


2.3.2.1       Acceptance Rate Interaction
There are five acceptance rates within TMA. Each acceptance rate must be met, so there is not a
hierarchy to them, but there is an order in which they are checked. The five acceptance rates, in
the order in which they are checked:

               Gate acceptance
               MFX acceptance
               TRACON acceptance
               Airport acceptance
               Runway acceptance


Because each acceptance rate must be met, each acceptance rate must be set correctly to ensure
desired results. For example, setting the airport acceptance rate to unrestricted will not result in
an increase in capacity if the gate, MFX, or TRACON acceptance rates are set to a value that is
restricting traffic flow.


2.3.3       Airport Configuration Summary Window
Definition – A brief banner/header description of the present selected airport status and any
scheduled future changes of each adapted airport. There are also check buttons for controlling
the display of this information at the top of the Timeline display.

When to Use this Function – To toggle the display on the top of the Timeline or, if the display is
off, get a quick summary.

How to Access – From the Control menu on the Status and Schedule window or F7.


2.3.4       Alert Notices
Definition – There are a series of notices that the system opens when a problem arises. Some
will disappear without user intervention; some alert the user to serious problems, which require
System Administrator (SA) intervention, especially if they do not disappear quickly by
themselves. Many will cause an Update Failure box, accompanied by a large red X, to open.
These conditions include Loss of Scheduler updates and Loss of Radar Track updates.

TMA Reference Manual                                                               CSC/TMA-09/0104
November 2009                                                                      TGUI Functionality


Other Interface Status dialogs alert to Loss of and Restoration of the following conditions:
Internal Weather Interface, External Weather Interface, Host/ERAM Interface, ARTS Gateway
Interfaces, STARS Interface, TMA outputs to the Host/ERAM, Collaborative Arrival Planning
(CAP) Interface, and Traffic Flow Management System (TFMS) Interface.

A TGUI can be configured, through adaptation and the M&C setup of that TGUI, to only show
certain alert dialogs or status of specific interfaces. The TGUI can also be configured via
adaptation to have the interface status dialogs be shown only upon failure and/or have the
restoration of an interface automatically close the failure dialog.

When to Use this Function – These are automatic alerts and not user controllable.

How to Access – Not accessible by the user; system-generated.


2.3.5       AutoSwap
Definition – Provides capability to swap STAs of aircraft in a stream class, to restore aircraft to
the order they are expected to arrive at the fixes and runways. Ordering can be by the time of
crossing the holding or outer arc (adapted choice) which indicates the time the flight entered
holding, or by the flight’s altitudes at the time the AutoSwap command is entered. After an
action that reschedules flights, aircraft that are in holding may not receive accurate STAs, as the
STA is based on the ETA for the flight at the time of the scheduling action. Aircraft that are
moving in a direction away from the fix/runway have ETAs that are later than actual later
flights that are moving towards the fix/runway.

When to Use this Function – When aircraft are in holding and there is an action that reschedules
flights, such as a reschedule from an aircraft’s scheduling pop-up menu or a configuration
change.

How to Access – The access methods to get the dialog are:

               From an aircraft’s Scheduling Pop-up Menu
               Control +s for AutoSwap by holding arc
               Control +S (Shift s) for AutoSwap by altitude


2.3.6       Blocked Intervals for an MFX or a Threshold (THD)
Definition – Stops the scheduling of arrivals for a determined amount of time at a selected meter
fix or runway.

When to Use this Function – Meter Fixes and runways are blocked when the user wants to
prevent aircraft from being scheduled to use them. Some reasons for these blocks can include

2.3.13      Create a Slot
Definition – A slot is used to reserve a place in the queue on an MFX or THD timeline for an
aircraft that is not in the area at present but is expected to arrive later and need that slot. The
slot is treated as an aircraft for scheduling and separation purposes. The slot, therefore, is
chosen from the six aircraft categories.

When to Use this Function – When an aircraft is expected to arrive later, but needs to be
integrated into the traffic flow.

How to Access – Right click on a timeline to access the pop-up menu. Make the appropriate
choices.


2.3.14      Delay Reporting
Definition –The delay begins when the minimum possible delay for an aircraft exceeds the user-
specified delay threshold. Delay Reporting performs the following activities:

               Tracks accumulated delays within Center airspace
               Saves delay tracking data to retrievable report files
               Preformats reports for hardcopy print


When to Use this Function – Can be used to record/document delay information at an adapted
arrival airport.

How to Access – F6 or from the Control menu on the Status and Schedule window. The details
of the delay reports are arranged using the Delay Reporting Settings dialog box. These
parameters include:

               Threshold for reportable delay
               Delay period closeout time __ min after last reportable delay
               Delay Started/Ended Dialog Box On/Off

2.3.15      Departure Airports
Definition – Lists all the internal departure airports for the adapted primary airport and allows
the user to specify scheduling parameters in use at each airport. The TGUI can be configured,
through adaptation and the M&C setup of each TGUI, to allow changes to only the departure
airports in the facility that is using that TGUI. Scheduling parameters that can be modified are:

    1. Configurations – defines the default runways for internal departures

    2. Departure buffer – specifies amount of delay that an internal departure will be
       scheduled to take after departure instead of on the ground

    3. Parameters for ETD hovering – controls whether an unscheduled internal departure that
       does not take off as planned will have its estimated times adjusted

When to Use this Function – To view and/or change the scheduling parameters of one of the
Departure Airports, also known as Satellite Airports. Providing the current departure
configuration facilitates the calculation of more accurate ETAs for internal departures to an
adapted airport. The departure time buffer allows the user to factor in the uncertainty of
meeting departure times and allow for unexpected delays in flight. ETD hovering will keep
flights that don’t depart on the visible timeline and show the earliest ETA they can meet.

How to Access – Control+Z, or when the user left clicks the Satellite button on the Status and
Schedule window, or when the user left clicks on the Set Manually button on the
Configuration and Runway Settings dialog when changing a configuration.


2.3.16      Display
Definition – Display is one of the two pull-down menus located near the top of the Status and
Schedule window.

all TGUIs with the same group ID. The tags are highlighted for a site-specific time.

When to Use this Function – To locate an aircraft on a timeline using its ACID.

How to Access – @ (Shift+2) or from the Control menu on the Status and Schedule window.


2.3.19     Fix/Arc Delay Amounts
  Definition – Sets the maximum delay amount that can be absorbed between each pair of
  fixes/arcs, and the maximum delay at the outermost arcs. Delay amounts are in minutes.
  Specific arc data is only shown if that level of arcs is adapted at a site. Meter fix and runway
  STAs are not rescheduled; delays are just reallocated between the meter fix and the arcs.


When to Use this Function – When the amount of delay to be absorbed in a region of airspace
needs to be modified.

How to Access – From the Status and Schedule window.

  that is adapted)



2.3.20     Freeze Horizons
Definition – The freeze horizon settings determine the point at which an aircraft’s scheduled
time of arrival at the feeder gate is frozen and no further scheduling takes place. The Freeze
Horizon dialog allows the setting of freeze horizons in either minutes or nautical miles, based on
adaptation, for the different stream classes at various gates. Nontracked aircraft are frozen based
on the time-based freeze horizon for the appropriate stream class. The freeze horizons can also
be set to the adapted defaults. Freeze horizons can be enabled by destination airport, if that
option is enabled in adaptation. Normally, aircraft in a super stream are frozen when a later
flight freezes, to ensure that the flight doesn’t lose its slot. If asymmetric freezing is enabled,
flights are only frozen if the later flight is in the same stream class.

2.3.22     Graph Controls Dialog
Definition – Similar to the manner in which the Timeline Controls Dialog provides a subset of
the Timeline Setup Dialog for adjusting the settings of an individual timeline, the Graph
Controls Dialog provides a subset of the functions on the Graph Setup Dialog. Whereas the
Graph Setup Dialog enables the setting of parameters for up to all nine possible loadgraphs,
the Graph Controls Dialog provides a quick method to adjust the parameters on a single graph.

When to Use this Function – When the need exists to modify an existing graph and the user
prefers this simpler dialog to the Graph Setup Dialog.

How to Access – The Graph Controls Dialog is displayed when the user left clicks on a graph
label pushbutton. This is the numeric label that appears in the upper right corner of each graph.

                            above 20 is 1.
                            Interpreting the values displayed on graphs can be complex. Refer to
                            Paragraph 2.3.23.1
   Window Start Time        Determines whether the traffic count window is based on fixed time periods or
                            sliding intervals. See “Understanding Loadgraph Values” under the Graphs
                            heading for detail on the function of this setting.



2.3.24     Graphs (or Loadgraphs)
Definition – Graphs provide an alternative way to display traffic and delays. The standard TGUI
graph window is composed of up to nine graphs (each of which can be enlarged to fill an entire
screen). Each graph can have up to four plots, where the actual data is accumulated. A
horizontal load limit line can be displayed to provide context for the data. In addition, the user
can use the middle mouse button to display a vertical reader line on the Graph Window. The
user can also use the right mouse button to display a horizontal reader on the Graph Window.
Pressing both the middle and right mouse buttons displays the vertical and horizontal reader
lines simultaneously. The reader lines aid in graph comprehension.

When to Use this Function – To graphically display defined traffic flows and their associated
ETAs, STAs, and delays.

How to Access – F2 or from the Display menu on the Status and Schedule window.


2.3.24.1      Understanding Loadgraph Values
The values displayed on TGUI loadgraphs require some interpretation and an understanding of
how the values displayed are calculated. Frequently, it may be desirable to try to compare
displayed loadgraph values with the values displayed on the Traffic Count Window. For a
number of reasons, these values may vary from each other. They can only be directly compared
when the settings affecting how data is displayed on each match exactly. This section explains

                                                   2-12
TMA Reference Manual                                                              CSC/TMA-09/0104

two of the most complex items affecting displayed loadgraph values: the traffic count window
field and the window start time field that appear on the Graph Setup and Graph Controls
windows. Note that while there is a Traffic Count Window display in the TGUI that shows
numeric traffic counts, it is not to be confused with the traffic count window field on the graph-
associated windows. They are completely different concepts.

First, examine one of the simplest situations in which a loadgraph is set to display a bar graph
using a ten-minute traffic count window with a fixed hourly window start time. In this case, the
TGUI counts all of the aircraft in each ten-minute block starting from a fixed point in time,
which is the top of the hour. The following example shows aircraft counts for a 30-minute
period in this situation and the resulting bar graph:

                              10:20-10:30                      8




                                Figure 2-1. Loadgraph of Sample Data


In this simplistic example, it can be seen that the number of aircraft in each ten-minute time
period matches exactly to the number displayed on the loadgraph. Also, it is likely that the
displayed values will match the values displayed on the Traffic Count window in this scenario.
However, this is one of the simplest situations.



                                                2-13
TMA Reference Manual                                                               CSC/TMA-09/0104
November 2009                                                                      TGUI Functionality


The key concept in this example is that the traffic is counted in ten-minute blocks as specified by
the traffic count window field on the Graph Setup (or Graph Controls) window, and the start
time is fixed on the hour. Changing to the traffic count window field to a different value simply
changes the time period over which the traffic count is aggregated. For instance, if the value is
changed to 15 minutes, then all the traffic in each 15-minute period would be counted together.
For example, using the previous sample data, this new traffic count window results in data like
the following:


                       Table 2-8. Sample Loadgraph Data over 15-Minute Periods

                             Time Period         Number of Aircraft
                               10:00-10:15                5
                               10:15-10:30                15


This would occur if all seven aircraft in our previous 10:10-10:20 time period actually arrived in
the time period of 10:15-10:20. While possibly unrealistic, the intent here is to show how the
traffic count window value can affect the data. In this case, the traffic count window value of 15
minutes would cause the increase in traffic in the next time period to appear much more
dramatic than it did using a ten-minute window.

The window start time setting can also have implications on the displayed data. In the first
example, the window start time was fixed based on the top of the hour. Therefore, the data is
displayed in straightforward ten-minute blocks. However, if the window start time is set to
sliding, this becomes less straightforward. A sliding window start time means that the start and
end of each traffic count window time period slides with the clock. For instance, in the first
sample data, the first time period for displayed data of 10:00-10:10 would only be true right at
10:00. When the clock advances to 10:01, the time period in this window interval becomes 10:01-
10:11, at 10:02, the window interval is 10:02-10:12 and so forth. The same would be true for each
subsequent window interval after the first.

The important issue here is that a sliding time scale means that the resulting loadgraph can vary
dramatically in appearance from a loadgraph produced from a fixed time scale. It is much more
likely to appear skewed towards either unordinary high or low counts during short periods of
bunching or gaps in counted traffic. A sliding scale is also much less likely to produce counts
that are comparable to those displayed on the Traffic Count window.

The example shown in Figure 2-1 uses a bar graph because they are easier to understand than
line graphs. If a loadgraph is set to display a line graph instead of bar graph, the displayed
counts will have added complexity in interpretation. It should also be noted that line graphs can
only have a sliding time scale, a fixed time scale option is not available. In this case, the
calculated and displayed value at each minute is a count of all traffic over the specified traffic
count window period. This means that using a ten-minute window setting results in a count of
all traffic from the 5 minutes before the time mark to be plotted, through 5 minutes ahead of the
time mark. Therefore, using a ten-minute window, the plot for 10:10 indicates all traffic counted

from 10:05-10:15, the plot at 10:11 indicates all traffic counted from 10:06-10:16, and so on.
Figure 2-2 illustrates this concept:




                       Figure 2-2. Illustration of Sliding Time Window on a Line Graph


In summary, many factors interact to affect exactly how data appears when plotted on a
loadgraph. By changing the settings of the traffic count window field, the window start time
field, and the graph type, the same traffic count data can produce widely varying plots in
appearance. Understanding the function and interaction of these settings can greatly assist in
loadgraph interpretation.

2.3.28        Internal Departures
Definition – Internal departures are flights that begin at other (satellite or departure) airports
within the Center or TRACON airspace. The Internal Departures window has three main parts:

        1.         A list of Unscheduled Flights
        2.         An area for the Flight Data for a selected flight
        3.         Areas for Scheduled Flights, subdivided by areas for each adapted airport


The flights listed may be sorted and filtered by a variety of criteria. Unscheduled flights may be
sorted by ACID, arrival airport, origin, or ETA. Unscheduled flights can be filtered by the arrival
airport and the center they depart from. Scheduled flights can be sorted on ACID, origin, Type,
MFX, Scheduled Departure, or STA. There are buttons to Schedule a highlighted unscheduled
flight, and to Reschedule or Unschedule a highlighted scheduled flight. The Schedule and
Reschedule buttons invoke the Schedule a Departure dialog box.

A TGUI can be configured, through adaptation and the M&C setup of each TGUI, to allow
scheduling of flights from only the departure airports in the facility that is using that TGUI.

When to Use this Function – Whenever there is the need to view, schedule, unscheduled, or
modify information for Internal Departures.

How to Access – F4 or from the Display menu on the Status and Schedule window.


2.3.29        Local Display
Definition – Controls the displays and shows which displays are active. A Display is defined as
a Timeline or Graph. A Display File is the combination of a Timeline file and a Graph file. The
top of the dialog box has buttons for predefined Display Files. The buttons are populated with
file names. Selecting one invokes that file. The lower half of the dialog box lists the names of the
active files and has buttons to invoke new files. There is also a button that invokes the Save
Display File dialog to (create and) save a new display file.

When to Use this Function – This dialog box is one way to change the (active) Timeline or
Graph file displayed. It is the only way to invoke a new active display file and to create a new
display file.

How to Access – Either F3 or from the Display menu on the Status and Schedule window.


2.3.30     Manual Rescheduling
Definition – The manual rescheduling function allows the user to move an ACID tag from its
present position to an earlier (advance) or later (delay) position on the Timeline. Times at other
fixes/arcs and the runway will be calculated using the delay absorption parameters (e.g.,
AMDT, TRACON buffer). Care must be used in this function because other restrictions (like
AAR) are not checked when the aircraft is manually rescheduled. This function may also
override minimum separation requirements.

When to Use this Function – To override the TMA’s programmed scheduled sequence and to
manually adjust STAs for specific arrivals.

How to Access – Place the pointer on the ACID tag, middle-click, and move the tag up or down
on the timeline.


2.3.31     Manual Scheduling of Internal Departures
Definition – Manual Scheduling of Internal Departures enables the scheduling of internal
departures using simple drag and drop of aircraft tags from departure timelines. The operations
that can be performed are equivalent to operations using the Schedule a Departure dialog.
Specific actions on the dialog can be disabled through adaptation, to restrict the capabilities of a
TGUI at a site, and will have the same effect on the equivalent drag and drop actions. Table 2-10
summarizes the drag and drop operations that can be performed, and their equivalents, when
using the Schedule a Departure dialog.

Drag and drop scheduling’s effect on previously scheduled flights can be controlled through
adaptation. If specified in adaptation, a flight that is dropped at a time will be moved behind
other flights, in order to not add delay to overhead streams. Otherwise the flight is scheduled at
the specified time, delaying other flights. The adapted state of the drag and drop capability is
indicated on the Status and Schedule Window, in the Delay Scheduled Flights for Drag and
Drop label

A TGUI can be configured, through adaptation and the M&C setup of each TGUI, to allow
scheduling of flights from only the departure airports in the facility that is using that TGUI.

When to Use this Function – When there is a need to schedule the departure of flights that
originate within or near the ARTCC boundary (that is, an internal departure) that are currently
being displayed on a departure timeline.

How to Access – Manual scheduling for internal departures is performed by middle mouse
button clicking on an aircraft tag on a departure timeline and then dragging the aircraft tag

while continuing to hold down the middle button. Releasing the middle button then drops the
aircraft tag at the spot on the timeline over which the middle button was released.

The same methods can be used on arrival timelines. In that case, dragging on the estimated side
of the arrival timeline is the same as dragging on the estimated side of a departure timeline, and
dragging from the estimated to scheduled side of an arrival timeline is the same as dragging
from the departure timeline to an arrival timeline.

2.3.32      Map to Primary
When a configuration change occurs at an airport that has satellite airports associated with it,
the configurations at those internal departure airports must also be changed. This is done
quickly by using the Map to Primary function. For each configuration of the primary airport,
there is a corresponding default configuration for each internal departure airport. The Map to
Primary function automatically sets each internal departure airport's configuration to this
corresponding default. The Map to Primary function is on the Configuration Change dialog
and on the Departure Airport Configuration dialog.

The TGUI can be configured, through adaptation and the M&C setup of each TGUI, to allow
changes to only the departure airports in the facility that is using that TGUI.

2.3.41      Save File Dialog Box
Definition – Used to save either a Timeline file or a Graph file. If a file of the same name already
exists, an Overwrite Warning dialog box appears. That dialog box allows the overwrite or
cancellation of the operation.

When to Use this Function – This dialog box is called during the Save operation.

How to Access – From the Timeline Setup or Graph Setup dialogs when the Save… button is
selected.


2.3.42      Schedule a Departure Dialog
Definition – Enables scheduling of internal departure flights for arrival at the primary TMA
airport. When accessed for a flight, the dialog initially displays a proposed ART and Desired
STA. The ART defaults to a time based on adaptation settings. The Desired STA is derived from
the ART and the computed time-to-fly. The user can choose to schedule the aircraft to the meter
fix or the runway threshold. They can also choose to change the scheduled route’s meter fix,
departure runway, or arrival runway. After the desired settings are made, the user can select the
Schedule pushbutton to schedule a proposed departure time. TMA calculates the closest
available STA that matches the Desired STA or a later STA if the Desired STA is not possible,
and schedule the aircraft in proposed state. The system then calculates a suggested departure
time and fills this value into the Scheduled Dep field. The user can then:

               Unschedule the flight
               Accept the proposed schedule that assigns the departure time to the aircraft
               Freeze the proposed schedule that assigns the departure time, which treats the
                STA as a manual assignment


In addition, the user can use the Scheduled Dep field to manually enter a desired departure
time, overriding, or in place of, the calculated suggested departure time. If possible, the aircraft
can then be scheduled to depart at the entered time.

A Departure Time Buffer can be entered, if enabled in adaptation, to specify the amount of delay
that should be scheduled to be taken by the flight after departing. This value will have no effect
if a flight does not require any delay.

Specific entry fields, and menu, toggle, and the freeze buttons can be disabled through
adaptation to restrict the capabilities of a TGUI at a site. Restrictions on the dialog will have the
same effect on the equivalent drag and drop or scheduling menu items.


When to Use this Function – When there is a need to schedule the departure of flights that
originate within or near the ARTCC boundary (that is, an internal departure).

How to Access – The Schedule a Departure dialog is displayed when a user selects a flight on
the Internal Departures window and selects the Schedule… pushbutton or double-clicks on a

2.3.46      Single Gate Free Flow (SGFF)
Definition – Allows arrivals at a selected MFX/gate to have priority over other meter
fixes/gates. Depending upon arrival constraints, these aircraft will receive minimal or no delays
while arrivals at other meter fixes/gates receive additional delays.

During a metered rush, a free-flowing feeder gate does not receive meter times. The feeder gate
only delays aircraft for the minimum in-trail spacing and other relevant scheduling constraints.

Delays that are to be assigned to aircraft arriving over the free-flowing corner post will have to
be redistributed equally to aircraft at the remaining gates.

When to Use this Function:

               During heavy rush periods where one MFX/gate has the majority of the arrival
                traffic
               During times of adverse weather conditions (for example, thunderstorms, icing,
                and turbulence) when it may not be acceptable to delay aircraft in or near an
                arrival gate
               When equipment problems limit the sector’s ability to absorb delays


How to Access – From the Status and Schedule window or by clicking the middle mouse key
while dwelling and dragging in the middle of an MFX timeline. In either case, the SGFF dialog
box appears and needs to be completed.


2.3.47      Show Meter Lists
Definition – Enables the sending of Meter Lists from TMA to controller displays.

When to Use this Function – When controllers are required to use the TMA-generated times,
this function must be enabled to display the MFX times on the controller’s workstation.

How to Access – The switch (check button) is near the top of the Status and Schedule window.
Two-way Host connection must be established for this to work.


2.3.48      Special Use Airspace (SUA)
Definition – Provides the capability to control when a Special Use Airspace (SUA) is active,
causing TMA to use adapted routes that pass around the SUA. Dialog is only available if SUAs
are adapted at a site.

When to Use this Function – When the status of an SUA has changed.

How to Access – Control+U or from the Control menu on the Status and Schedule window.

2.3.49     Status and Schedule
Definition – The Status and Schedule window is the center of the TGUI. It presents the status of
many of the control parameters such as AAR, Configurations, TAR, and so on, and offers the
capability of changing most control parameters. For example, to change the AAR, select the
AAR… button. To change the airport configuration, select the Config… button. The airport to
be controlled is selected here. Messages to Host/ERAM are sent from a dialog accessed from
this window. If the user selects Future Scheduling Changes, the Schedule functions permits
future changes of parameters.

When to Use this Function – For all Host/ERAM interfaces, to view or change present Status
parameters, or to view or change future Scheduling parameters.

How to Access – F1


2.3.50     Stream Classes for Time-Based Metering
Definition – Sets MiT separations by individual super streams for all super streams that have a
specified engine type, or by shortcut entries that specify which stream classes to modify. Super
streams can be dynamically created to supplement the adapted combinations of stream classes.
The Time-Based Metering dialog contains a set default button that is only applicable to the
setting of the MiT.

This dialog also supports enabling asymmetric freezing for super streams. Normally, aircraft in
a super stream are frozen when a later flight freezes, to ensure that the flight doesn’t lose its slot.
If asymmetric freezing is enabled, flights are only frozen if the later flight is in the same stream
class.

When to Use this Function – To implement Time-Based Metering globally or by gate or flow
pattern between selected Stream Classes when a MiT restriction has been set. To enable
asymmetric freezing for a super stream.

How to Access – From the Status and Schedule window.


2.3.51     Swap
Definition – The Swap function allows the user to switch the STAs of two flights. The STAs for
the reference points (OOAs, O3As, etc.) upstream of the STAs that are swapped will be
recalculated, if enabled in adaptation, in order to have realistic STAs. When departure aircrafts’
STAs are swapped, the scheduled departure times will also be swapped if the flights are
departing from the same airport and departure runway.

When to Use this Function – Use to override TMA’s programmed scheduled sequence and
manually adjust STAs for specific arrivals.

How to Access – Place the pointer on the ACID tag, left-click, and move the tag up or down on
the timeline. Release mouse on aircraft to swap with. Swap function can also be accessed by
right clicking on an aircraft to access the scheduling popup menu.

                         Chapter 3 ― PGUI Functionality


3.1     Introduction
The planview display is a graphical representation of traffic in a specified airspace, Center or
TRACON. A PGUI is much like a controller’s DSR. When the TMA PGUI is initialized, a full
Center airspace radar map appears on the monitor. This is the default map. Other predefined
Center or TRACON airspace radar map views are available using Map View Options and Map
Options. All maps can be moved, zoomed, and customized to display features such as
timelines, sequence lists, range rings, waypoints and meter reference points, and routes.

The primary function of PGUI is to relay aircraft flight plan, track data and weather information
to the user. PGUI consists of dynamic features manipulated by controller inputs from keyboard
entries, quick keys, mouse clicks, and function keys. PGUI sends messages from the controller
inputs to the Communications Manager (CM) for processing and display information.


3.2     Functional Overview
The PGUI displays graphical information on control of air traffic, including such entities as
advisories, timelines, and aircraft data blocks. It responds to controller keyboard or mouse
inputs and sends appropriate messages to the CM.

The PGUI provides a Planview display to the traffic manager. Data tags or Datablocks identify
aircraft on the display. The system displays various calculated aircraft routes and advisories.
The PGUI offers optional timelines similar to those on a TGUI. Each timeline can display traffic
according to gates, runways, ownership, and other details. Typically, PGUI’s timelines indicate
airways, final approach paths, and preferred routes to the targeted destination.

The PGUI uses data blocks to label traffic and uses special colors to provide additional
information when available. It lets the Traffic Management Coordinator (TMC) see all the
aircraft in the entire airspace, similar to monitor mode. It does not support controlling functions
such as capturing waypoints, handing off aircraft, accepting handoffs, and other functions.


3.3     PGUI Map Window
The Map Window can display the ARTCC airspace, the TRACON airspace, or the airspace
associated with any of the feeder gates, which for ZFW/DFW, for example, are Bonham, Cedar
Creek, Bowie, and Glen Rose. The Map Window is resizable using either a pull-down menu
option or a quick key entry, and it can display Timelines and the Sequence List.

At the bottom of the Map Window is a scratch pad message area. The scratch pad consists of
two data input boxes. The left box is not used and the right box is used only in development
simulations for sector handoff data entry. Below the scratch pad is a data line that serves as a

November 2009                                                                  PGUI Functionality


message area. It can be repositioned with the scratch pad but is not removable from the Map
Window.

Map Window parameter characteristics, defaults setup, sequence list options, and timeline
display options are configured by way of a series of Display Option Panels. These panels are
movable, resizable, and are opened and closed using Function Keys. If moved and cleared, they
reopen in the last position to which they were moved.

A complete list of files created using individual panels can also be accessed using the Load
Display Files, F4 panel. The selections are as follows:

               Master File
               Center Zoom File
               Color File
               Datablock File
               Map File
               Sequence File
               Setup File
               Timeline File


Default settings can be used for any or all of these files, and each may be customized by
individual users and saved for future reference/use. They are all accessible from associated
individual panels on the PGUI (F2, F3, F7, F10 and F11) and from the Load Display Files panel,
which is opened/closed with the F4 key. Pressing the OK button also closes the Load Display
Files panel.

The PGUI Map Window has lines indicating airways, final approach paths, and preferred
routes to targeted destinations. It can be configured to show objects such as waypoint fixes,
VHF Omnidirectional Ranges (VORs), intersections, and special use airspace. The default color
for these objects is white. The Map Window labels traffic by means of Datablocks and can be
configured to use color to denote additional information. The Map Window information is
updated by radar returns every 12 seconds for enroute tracks and 5-6 seconds for TRACON
tracks. The map display has a fixed scale bar that shows a measured distance of 25 nautical
miles on the map to assist the user in determining corresponding distances shown.

Each aircraft is shown on the TMA PGUI displays as a diamond, triangle, or pound sign
representing the aircraft’s position in the airspace. The color of each arrival aircraft symbol
represents the aircraft’s assigned meter reference point (MRP) gate. The default color for the
symbol of arrival aircraft is green. Symbol color may be changed and used to denote MRP.
When the mouse cursor dwells over an aircraft symbol, leader line, or Datablock, a light green
circle surrounds the aircraft symbol and the Datablock turns blue.

3.7     TRACON Configuration Status
The configuration status of all TRACON data feeds is displayed on the PGUI TRACON
Connection Status (F8) panel. The panel pops up when there is a change in any of the TRACON
connections if the Popup Window on Status Change checkbox is selected. The TRACON
connection status message displays TRACON Data Available if any of the ARTS or STARS
interfaces are connected, and displays TRACON Data Unavailable if none are connected.

Update Failure dialog and/or red “X” informs the user that the PGUI has lost radar track
updates that could lead to misleading or incorrect information.

If the radar updates are lost from all data sources for more than a site adaptable value, a red “X”
will also appear across the PGUI window in conjunction with the Update Failure dialog (see
Figure 3-1). The red “X” will be displayed unless it is specifically disabled in adaptation.

Delayed Data dialog and the yellow “X” inform the user that the PGUI is receiving delayed
track data. The amount of delay is determined by the difference between the time the PGUI
receives a track and track source time. If the track updates are delayed for more than a site
adaptable value, a yellow “X” will appear across the PGUI window in conjunction with the
Delayed Data dialog (see Figure 3-2). The yellow “X” will be displayed unless it is specifically
disabled in adaptation.

            Chapter 4 ― Monitor and Control (M&C) Functionality

4.1     TMA M&C Functional Overview
The TMA Monitor and Control (M&C) Subsystem is the central administrative component of
the TMA system architecture and functions to manage and regulate the resources of, and
components distributed with, the TMA operational software. The TMA M&C software manages
an automatic system with built-in failure recovery using Simple Network Management Protocol
(SNMP). The dedicated computer resources for TMA M&C isolate its interface and its central
control functions from the TMA operational applications. This arrangement ensures these
functions impact the TMA operational application as little as possible.

When TMA is running, the TMA M&C subsystem serves as an automated monitoring and
failure recovery system. The subsystem provides failure alerting and diagnostic records. The
TMA M&C also enables the operator to carry out the following functions:

               Properly configure and start the TMA M&C and all TMA component hardware
                and software
               Start Multi-Metering Gateway (MMG) and ARTS Data Interface (ADIF) data
                feeds to TMA
               Monitor, diagnose, and resolve system problems through visual and auditory
                alarm messages
               Obtain assistance and maintenance, as needed, for the TMA system
               Properly stop and start TMA and selectively reboot/shutdown TMA boxes
               Select and control system data recording levels
               Set the current level of TMA data flow through to the Host
               Perform various ancillary tasks, such as screen captures, core finds, and so forth
The TMA M&C Operator’s Manual contains more detailed information on the M&C’s role with
regard to TMA System Monitoring, Alarm and System Diagnostics and System Configuration.


4.1.1       The M&C’s Role in the TMA Fault-Tolerant Architecture
The TMA system’s fault-tolerant design has been developed to ensure high levels of
availability. To accomplish this, the M&C receives system-wide operational status data by way
of the SNMP, which is the most widely-used management protocol in use today in data
networks.

The TMA M&C subsystem utilizes the SNAP-driven system status messages to manage all of
the resources of the TMA system. The TMA M&C provides system configuration control for the
overall TMA system, ADIF, and MMG, and is responsible for monitoring the operational health
and status of all configured components (see Figure 4-1, Typical Site Diagram updated to
include the En Route Departure Capability (EDC) GUIs installed at the EDC deployed sites).

The fault-tolerant architecture of the TMA system includes redundant components and
communications paths, and is functionally divided into two distinctly separate strings ― an
operations string and a support string. On the operations string, the TMA M&C software on the
primary computer monitors the TMA processing software, hardware, the LAN, and all internal
and external connections. A secondary TMA M&C monitors the primary computer’s health and
status, and takes over as the primary in the event of failure.

The support string also includes a TMA M&C computer and is designed to enable the testing of
adaptations, upgrades, and patches. The support string also provides the capability to replay
previously recorded data from the operations string, which is an invaluable resource in the
diagnosis and troubleshooting of system problems.

November 2009                                                   Monitor and Control (M&C) Functionality


4.2     The M&C Software
The M&C application software combines Commercial Off-the-Shelf (COTS) products with
custom-developed software modules written specifically for TMA. The M&C centralizes the
tracking of all workstation health regarding error messages, network congestion and system up
time. The M&C's GUI provides general connection health and system loading information, and
displays a graphic representation of the TMA network topology, incorporating icons that
represent workstations, routers, and various network equipment. A multilevel diagram is
displayed on the M&C main map indicating those devices and network segments that are
healthy and those areas requiring attention.

Color coding of icons representing the system components confirm their operational state.
When events from the failure or degradation of a device or process are detected, the source of
the problem is immediately identified and reported.


4.3     TMA M&C System Configuration Capability
The TMA M&C system enables the operator to configure the TMA for specific applications, and
to subsequently store and retrieve these user-specified parameters as unique configuration files.
This capability includes the retention of process allocation and command line arguments, and
enables M&C operators to accommodate individual preferences for the look and feel of the
desktop display of system information. These profiles are then named like any standard file
name and can be loaded from a file browser.

The Manual Configuration module enables M&C operators to configure the TMA system by
way of a simple drag-and-drop method of allocating processes to devices.

Note: If running in EDC mode additional information is provided for Manual Configuration in
the M&C Operator’s Manual.


4.4     TMA System Performance Monitoring
The M&C application software constantly polls all configured devices and active TMA
processes in order to assess, log, and report the operational health and status of the TMA
system.

HP OpenView (OV) is the COTS product at the core of the M&C's functionality. OV determines
all the generic elements of the network (that is, workstations, routers, network topology,
printers, and so forth) and monitors these elements continuously.


4.5     Failure Recovery and System Alarms

4.5.1      Failure Recovery
A key element of the M&C's functional mission is to provide fault detection, isolation, and
automatic failure recovery of both hardware devices and critical Traffic Flow Management
(TFM) processes. The M&C detects computer hardware failures by polling of the Internet

                                               4-3
TMA Reference Manual                                                                   CSC/TMA-09/0104
November 2009                                                     Monitor and Control (M&C) Functionality


Control Message Protocol (ICMP) daemon in each configured computer. The ICMP daemon
responds to IP-Ping requests sent from the M&C and responds accordingly. Upon detection of a
computer degradation or failure, the M&C uses a configuration table to implement the
appropriate action(s) given the applications resident on the failed device.

The TMA M&C immediately invokes casualty recovery procedures for TMA upon the detection
of failures. Processes connect to the M&C locally on their workstations, and are launched
locally. If a process fails locally, it is automatically detected by the M&C which then takes action
to correct the problem and reconnect it to the desired data source.

There are three types of failures:

        1. Node Failure – detected by polling that occurs at the central SMC (Hardware)

        2. Process Failure – detected locally on the workstation by the M&C and passed on to
           the centralized M&C

        3. Connection Failures – reported on by either the client or process server

The M&C's capability to recover selected software and hardware from failures is accomplished
by the use of redundant levels of hardware components and software processes. The M&C
regulates three primary types of system failures:

               Connection failures
               Process failures
               Workstation failures


In each case, these failures are reported to the M&C and are logged accordingly.


4.5.2       System Alarms
The TMA M&C’s main hardware and software maps are designed to provide a high-level
graphical depiction of system status. The alarm browser provides the TMA M&C operator with
an effective tool for quickly isolating and resolving system-related problems.

The alarm browser overlays the TMA M&C main map and displays a variety of system-
generated status messages categorized by type and color-coded by severity. The following list
provides a high-level description of the basic functionality of the TMA M&C alarm browser and
a listing of the mapped messages, events, and significance of reported error conditions:

               Error Alarms: Error alarms include a variety of esoteric message types that do
                not fit into other categories.
               Threshold Alarms: Threshold alarms are messages sent when some aspect of
                system operation, such as the amount of remaining hard drive space on a
                computer, falls below a set limit.

               Status Alarms: Status alarms are sent when a device on the network changes
                status (for example, from on to off).
               Configuration Alerts: Configuration alerts are sent when a device configuration
                is changed. For example, when the network interface card of a computer is
                replaced, the hardware address of the computer changes.
               TMA Alerts: TMA alerts are messages programmed into the TMA software to
                determine the status of TMA systems and services (for example, subsystems
                started normally).
               MMG Alerts: MMG messages relate to changes in MMG operation. Careful
                attention should be paid to these messages because the MMG data stream is vital
                to the functioning of the TMA system.
               Warning Alarms: Warning alarms are sent when events occur that may or may
                not be significant. These are typically adaptation-related.
               Uninterrupted Power Supply (UPS) Alarms: UPS messages involve problems
                with connected UPS units, such as low battery or low voltage.
               All Alarms: All alarms contains all of the previously described message
                categories.

                       Chapter 5 ― Online Help Functionality


5.1     Introduction
This section discusses the three types of online help functions available on the TGUI system and
the online help function available on the PGUI system.

5.2     TGUI Online Help
The TGUI has an Online Help function; see Figure 5-1. If running in EDC mode, see Figure 5-2.
The Online Help function is accessed using the Help key. The initial screen presents a list of
Quick Action Keys, with their Display and Key (to invoke). The software version and
adaptation version that are currently in use by the TGUI are displayed at the bottom of the
Online Help display. The Online Help dialog also indicates whether TMA is interfacing to the
Host or ERAM, and if interfacing with ERAM, a version number for the CMS interface is
shown.

There is a button, Help Index…, which is the gateway to the rest of the Online Help function.


5.2.1      Help Index and Search
The Help Index part, the top half of the dialog box, provides an alphabetic list of 12 topics, from
Delay Reporting to Traffic Count (see Figure 5-3). The list is scrollable. Each topic is
expandable into more detailed subtopics. A topic can be chosen from this list by category and
expanded into a detailed help text.

                                  Figure 5-3. Help Index and Search


The bottom half of the dialog box is a Search area (see Figure 5-4). Before search criteria are
entered, a scrollable alphabetic list of topics appears. (This is a complete list of topics covered by
Help.) Each of these topics is expandable. There are two ways to perform the Search: Search
List or Full Text Search. The former searches to see if the criteria are in the topic headings in the
list; the latter if it appears in the topic discussion. The Search yields a list of topics.

           Appendix A ― En Route Departure Capability (EDC)


A.1     Scope and Purpose of EDC
The En Route Departure Capability (EDC) is an enhancement of Traffic Management Advisor
(TMA). TMA is primarily an ARTCC tool that supports arrival operations into one or more
primary airports located within an ARTCC. EDC is an enhancement of TMA that extends its
basic technology to 1) manage en route traffic flows exiting an ARTCC to an adjacent ARTCC
and 2) provide metering points further out from the meter fixes at the TRACON boundary.
EDC replaces the older Host En Route Sequencing Program (ESP) functionality; because it is
based on more advanced TMA technology, EDC provides additional functionality, better
displays, and more accurate traffic flow predictions than ESP.

EDC replaces ESP in the En Route Automation Modernization (ERAM) environment. Sites that
previously used ESP can use EDC in its place. However, EDC is separate from ERAM, i.e., it is
distinct hardware and software that is not part of the ERAM program. Consequently EDC can
be deployed at an ARTCC and the ARTCC can use it operationally before ERAM is deployed
there.

Like TMA, EDC provides automation and displays to help ARTCC traffic management. It
provides traffic managers better, timelier situation awareness of the overhead traffic flows. EDC
provides functionality to de-conflict and schedule aircraft exiting an ARTCC’s airspace into
another adjacent ARTCC and provide additional de-confliction at arrival metering points
further out than the arrival TMA meter fixes. It assists ARTCC traffic managers in scheduling
and releasing departures from internal airports1 into overhead streams. EDC provides tools to
better manage mile-in-trail restrictions, and provides the functionality to time-based meter en
route (i.e., non-arrival) traffic flows.

EDC is adaptable to each ARTCC’s airspace and operations. Each ARTCC can specify up to 25
meter points, which for en route metering will normally be positioned at ARTCC boundaries
where major air routes exit the ARTCC’s airspace to an adjacent ARTCC, and for arrival
metering will be positioned where there was previously an arrival TMA outer arc. EDC
schedules and deconflicts aircraft crossing each meter point.

EDC is based on existing TMA technology, utilizes the years of TMA development and
refinement through operational use. In particular, TMA incorporates accurate models of the
flight characteristics of hundreds of aircraft, including accurate ascent and descent profiles, as
well as incorporating accurate models of weather conditions (wind, temperature, etc.) within
ARTCC airspace. TMA and EDC are able to generate estimated times of arrival (ETA) for
aircraft crossing defined meter points in an ARTCC’s airspace that are typically accurate to
within a minute. Traffic managers can utilize EDC’s predictions of traffic flows and traffic load

1An internal airport is an airport located within an ARTCC’s airspace. An external airport is located in
another (not necessarily adjacent) ARTCC. For EDC purposes, flights are scheduled from internal airports
to external destination airports.

at meter points, as well as EDC’s predicted departure release times from internal airports, to
make better traffic management decisions.


A.1.1       EDC Architecture and TMA
EDC is an enhancement to TMA deployed at ARTCCs where en route departure and metering
functionality is required. TMA can also be deployed without it at ARTCCs where it is not
required. Architecturally, TMA consists of hardware and software components organized in
three main collections of components: a Core Group, which provides basic services needed by
other TMA components; a TRACON Group, which deconflicts and schedules aircraft arriving at
one or more airports in the ARTCC; and a Meter Point Group, which implements EDC-specific
functionality for aircraft crossing specified points in en route airspace, typically at exit points
from an ARTCC’s airspace or at points further out in the arrival streams.

TMA installations include one Core Group and at least one TRACON Group. At ARTCCs
where the EDC capability is desired, TMA will also include a Meter Point Group.

TRACON Groups and the Meter Point Group can be started and stopped independently. This
means that, for example, an ARTCC’s TRACON Groups can go off-line for maintenance or due
to an equipment failure while still leaving the Meter Point Group operational.

EDC equipment is installed on both the TMA Operational and Support Strings.


A.2     Overview

A.2.1       EDC Function
The overall list of EDC functionality in TMA is as follows:

           Schedule departure aircraft at meter point (MP) arcs
           Deconflicts all of the EDC metering points in a center
           Deconflicts each aircraft over one MP in its route
           Provides independent scheduling of Super Stream Classes
           TMC may modify flow parameters for one region that do not affect flows elsewhere
           Combining and separating stream classes on TGUI governs which EDC airports are
              deconflicted together
           Allows current and two future flow change requirements
           Aircraft not crossing MP arc not scheduled
           Aircraft must be destined to an EDC airport
           Adapted crossing restrictions supported
           Departure airports must have adapted configurations for correct modeling


                                                A-2
TMA Reference Manual                                                                CSC/TMA-09/0104
November 2009                                                                            Appendix A


           Only jet aircraft will be adapted in EDC
           Configuration changes are not supported
           Multiple Meter Points (MMPs) enhancement provides:

                - Extended metering horizon for both arrival and En Route traffic

                - Up to 3 independently deconflicted Meter Points (MPs) to be employed with
                              EDC or Arrival TMA

           EDC Supports:

                - 128 destination airports

                - 25 MP arcs

                - 3 MP per aircraft

A.2.2       Displays

A.2.2.1       PGUI and TGUI Displays
EDC displays consist of a Timeline GUI (TGUI) and Planview GUI (PGUI), together referred to
as a dual GUI. An EDC display may also be configured in a single GUI configuration. These
GUIs are similar to the standard TMA GUIs.

EDC displays are installed and used in the ARTCC TMU. The specific quantity and location of
displays may vary from ARTCC to ARTCC, and will be determined by the Program Office in
accordance with site needs. Typically an EDC dual GUI will be used by traffic managers in the
TMU en route sequencing position. At ARTCCs with more than one en route sequencing
position, each position may require an EDC dual GUI.

EDC may also be used by the severe weather position to assist in rerouting flights and making
related traffic management decisions during severe weather conditions.

EDC displays will not be installed in the TRACON or ATCT.


A.2.3       TGUI Changes

A.2.3.1       EDC TGUI
In addition to the arrival metering provided in TMA, EDC provides support for metering at
facility boundaries. The major change in EDC is the reference points for which ETAs and STAs
are shown. In EDC aircraft are scheduled at Meter Points, similar to the Meter Fix Arc
scheduling in arrival TMA. Additional ETAs and STAs are generated for levels of Outer Points,
as is done for Arcs in arrival TMA. All scheduling parameters are for the Meter Points.
Scheduling is not done to airports, so arrival runway data and labels are not shown and no


                                               A-3
TMA Reference Manual                                                             CSC/TMA-09/0104
November 2009                                                                         Appendix A


scheduling parameters exist for the TRACONs, airports, or runways. Airports are still used in
EDC, to define streams of aircraft and allow for filtering of flights. Due to the large number of
airports in EDC, TGUI displays which show lists of airports provide for adapted grouping of
airports that can be used where the individual airports do not need to be referenced separately.

The airports list can be adapted to order the airports by row or column, and to alphabetize the
lists.

Dialogs that contain a TGUI Identifier in their frame and the TGUI Help panel will indicate
when the TGUI is in EDC mode. EDC dialogs that are different than the arrival TMA are
described in the following paragraphs. Arrival TMA dialogs that are not identified in this
section as being deleted for EDC will still be used in EDC. Information on the dialogs that are
not changed is in the arrival TMA sections of this document.


The following dialogs are removed in EDC mode because they involve scheduling parameters
for airports or TRACONs, and EDC is scheduling to points at the facility boundaries:

        1.      Blocked Runways
        2.      Configuration and Runway Settings
        3.      Configuration Search
        4.      Airport Acceptance Rate
        5.      Separation Matrix
        6.      TRACON Buffer
        7.      TRACON Acceptance Rate
        8.      Configuration Change
        9.      Configuration Change Status
        10.     Quickset


The following dialogs are removed in EDC mode because the functionality was not required to
provide metering to the facility boundary:

        1.      Single Gate Free Flow and the Free Flow Parameter
        2.      AutoSwap
        3.      Traffic Count
        4.      Delay Reporting


If current and future versions of the removed dialogs exist, both are removed in EDC mode.
When a dialog is removed for EDC, all methods of accessing the dialog (e.g., buttons on other
dialogs, function keys) have been removed.

November 2009                                                                      Appendix A


The independent scheduling by airport capability is not available in EDC mode. Dialogs will
not have the option to display airport toggles to specify which airport’s aircraft should be
rescheduled due to scheduling parameter changes.

The following TGUI CHI areas are modified in EDC. In addition to the general changes above
(e.g., meter points replace meter fixes), specific changes are identified.


A.2.3.2       Timeline Window
On the timeline, creating Blocked Slots is removed from the Create Slot or Blocked Intervals
Popup Menu. Flow change tags for airports, runways, and TRACONs will not be displayed
since the scheduling parameters cannot be set. The scheduling popup menu will be modified to
add items for rescheduling by stream class.

The following elements of the Scheduling Popup Menu are removed in EDC mode: Runway,
Allocate Runway, Proposed MFX, AutoSwap. The independent scheduling by airport capability
to reschedule and broadcast by sets of airports is not available in EDC mode.

On the Timeline Setup Window Dialog (Figure A-1), toggle buttons that provide a shortcut to
“Show runways at selected airports” will be removed. The Timeline Setup dialog toggles for an
engine type are disabled if the engine type is not adapted at the site.

A.2.3.3       Airport Configuration Summary Window
In EDC, the Airport Configuration Summary Data at the top of the timeline (see Figure A-2,
EDC Airport Configuration Summary Data) and the EDC Airport Configuration Summary
window (Figure A-3) only show EDCT data, as the other data shown in arrival TMA is for
scheduling parameters at the airport. Due to the increased number of airports in EDC, all/none
buttons will be added to the Airport Configuration Summary Window to simplify the selection
of airports to be displayed. If all airports are using EDCT, “All Airports” will be displayed on
the Airport Configuration Summary Data on the timeline instead of the list of all airport names

A.2.3.4       Graphs
In EDC, options for Load Limit lines for AAR are removed from the Graph Setup since there is
no airport arrival rate (see Figure A-4, EDC Graph Setup Window Dialog). The Plot Controls
dialog toggles for an engine type is disabled if the engine type is not adapted at the site (see
Figure A-5, EDC for Plot Controls Graph Window).

In the table that shows the filtering selections for each plot in the Graph Setup, if all airports are
selected then “All Airports” will be displayed instead of the list of all airport names.

A.2.3.5       Internal Departure Dialog
Filtering of unscheduled flights on the EDC Internal Departure Dialog (Figure A-6) will be by
meter points in addition to airports. Drop down frames will be displayed for the lists of airports
or meter points to filter by, if the list exceeds eight. The sort option for the list of unscheduled
flights has “Meter Point” added, to provide sorting by meter point.

The drop down frames for scheduled flights are per gate, instead of per arrival airport. The sort
option for the list of scheduled flights has “Arr” replacing “MFX”, to provide sorting by arrival
airport.

A.2.3.6       Schedule a Departure Dialog
The Schedule a Departure dialog’s “Arrival RWY” button and its label in the View/Change
Scheduled Route frame are removed since EDC is scheduling just to the meter point (see
Figure A-7, EDC Schedule a Departure Dialog).

A.2.3.7       Departure Airport Configurations
The “Map to Primary” button is removed, as there is no primary arrival airport in EDC (see
Figure A-8, EDC Departure Airport Configurations Dialog).




                       Figure A-8. EDC Departure Airport Configurations Dialog



A.2.3.8       Status and Schedule Window
The Airport Parameters and TRACON parameters sections (current and future) are removed in
EDC because scheduling is only done to the meter points (see Figure A-9, EDC Status and
Schedule Window). Meter List and EDCT control are moved to separate dialogs due to the
larger number of airports. A button on the Status and Schedule Window and a quick key is
added to access the new dialogs. Summary info is displayed. If all airports are using EDCT, “All
Airports” is displayed instead of the list of all airport names. SGFF data and buttons are
removed since SGFF is not required in EDC.

For meter point acceptance rates, an airport pull down list has been added to specify the airport
for which rates are shown since there are no airport radio button toggles on the dialog. A list of
future acceptance rate changes for all airports can be accessed by selecting the View Schedule
button. This brings up the Schedule for Gate and Meter Point Rates dialog.

A.2.3.9       Stream Classes for Time Based Metering
The shortcut buttons to set values by an engine type are disabled if the engine type is not
adapted at the site (see Figure A-10, EDC Stream Classes for Time Based Metering).
Restrictions can be set across super streams to provide an additional level of miles-in-trail
restrictions, using Multiple Super Stream De-confliction (MSSD). MSSD groups can be adapted
or created dynamically. The groups can initially be enabled or disabled, and later
enabled/disabled as needed. To create an MSSD group, select Create on the Stream Classes for
Time Based Metering dialog. The Create Super Stream Groups dialog allows the user to
dynamically group super streams and specify restrictions for the combined super streams.

The View Super Stream Groups dialog allows the user to see all of the current MSSD groupings
and see which have been enabled. The dialog is accessed by selecting View on the Stream
Classes for Time Based Metering dialog. This dialog also allows the user to modify a miles in
trail restriction, enable/disable an MSSD group, and access Create Super Stream Groups to
view/modify a group.

If multiple metering points functionality has been adapted, the meter points combined in an
MSSD grouping must be at the same level (i.e., not upstream/downstream of each other). An
error dialog will be displayed if the user attempts to group upstream/downstream meter
points. Without this restriction it would be possible to group multiple stream classes for the
same flight, which would result in problems with scheduling that flight.


A.2.3.10      Freeze Horizons
The capability for enabling/disabling freeze horizons by destination airport is not available in
EDC.

A.2.3.12      Meter Point Acceptance Rates
For meter point acceptance rates, a list of airports is provided so that the user can change the
airport for which information is being displayed.



A.2.3.13      Multiple Meter Points
If multiple metering points capability has been adapted, a flight may have up to three meter
points that it will be scheduled to. The following changes will be observed for those flights:
     The Aircraft Data Window will display data for all of the meter points
     On the timeline, timesharing of meter point data with the aircraft tag will display the
        meter point name applicable to the time of that tag
     Changing the meter point for an aircraft with multiple meter points will be disabled
        until all upstream meter points have been crossed and only one meter point remains. For
        a departure aircraft, this means that the meter point cannot be changed while the flight
        is not active, since it will still have multiple meter points to cross.
     Departures can only be scheduled to the first meter point that a flight will cross.
     Timeline Count functionality will count each displayed tag for a flight as a separate
        aircraft.
     The scheduling popup menu for a flight will contain a submenu for certain selections, to
        allow the user to specify which meter point or super stream for the flight should have
        the action taken. The following menu items are affected: Reschedule, Suspend/Resume,
        Freeze, Priority/No Priority, and Find Slot.

The functionality for creating super streams and multiple super stream de-confliction groups
cannot support the grouping of meter points that are upstream and downstream of each other
in flights’ paths. That type of grouping would cause problems in the scheduling algorithms, as
the same flight would be in multiple places when scheduling the streams of aircraft. Error
dialogs will be displayed if the user attempts to group upstream/downstream meter points.


A.2.4       PGUI Changes
The PGUI changes included in EDC disabled functionality related to assigned runway, engine
type (EDC currently handles Jets only) and TRACON items. Additional panel changes have
been made and are indicated in Section A.2.4.2 PGUI Function Panel Changes.


A.2.4.1       Global PGUI Changes
The global changes for EDC mode are as follows:

               Non-arrival aircraft FDBs displayed and colored properly
               Sequence List order based off of Display Point STA
               Removal of Sequence List title by assigned runway
               PGUI timelines will not filter by assigned runway or meter fix but by meter point

               Meter Fix Arc, Outer Meter Arc, Outer Outer Meter Arc, Outer-Three Arc and
                Outer-Four Arc have been renamed to Meter Point, Outer Point, and Outer Outer
                Point, Outer-Three Point and Outer-Four Point.
               New – Multiple Meter Points (MMP) support up to 3 MPs assigned to an aircraft.
               New - Aircraft having more than one assigned meter point, the settings for FDB
                type, color and direction will only apply to the most downstream assigned meter
                point.
               New – Aircraft having more than one assigned meter point and the “x” key is
                depressed while dwelling on an aircraft will bring up the “Suspend/Resume
                <AID> panel (see Figure A-11. Suspend/Resume <AID> Panel). The
                “Suspend/Resume <AID> panel display for each meter point assigned to a
                flight: a toggle button, meter point name, a “Suspend” label if the flight is
                currently being scheduled for that meter point, and a “Resume” label if the flight
                is currently suspended from scheduling from that meter point.
               New – Sequence list has been updated to show an aircraft at each assigned meter
                point. An aircraft may appear up to 3 times on the sequence list if all meter
                points are displayed.
               New – Aircraft having more than one meter point assigned and “Remove
                Aircraft” is set to “After Outside Radar Coverage” the aircraft will be removed
                from the upstream meter point entries in the sequence list after the meter points
                are crossed.
               New – As part of MMP, Outer Fix reference point has become obsolete. All Outer
                Fix references have been removed from displays and adaptation.
