23/07/08 1.3 Initial Published version
Cix VFR Club members Maurice Murphy and Richard Sinclair carried out all
the research into the thorny subject of Gliding within Flight Simulator. This
document is the result of their work. It is but a small reflection of the hours
of research and testing which was necessary to introduce powered pilots to
this silent Flightsim World. The Club owes them a big vote of thanks.
This manual is presented in five major parts
1) Background Information
2) Setting up FS2004 for Basic Gliding
3) Setting up FSX for basic Gliding
4) First Flight
5) Advanced Gliding Tools:
For the first Club gliding event, members need only read and follow the
section for setting up their version of Flight Simulator (Sections 2 & 3) and
section 4 for a basic gliding cross country flight. The remainder of section 1
is useful background information.
1.1 Forces To Defy Gravity
The Holy Grail of man‟s timeless quest for flight was to find forces which
would defy gravity and allow an object, specifically a person, to stay up in
the air and not fall. A number of such forces have been discovered:
To name four, and there may be others. The two we are interested in are
upward wind and aerodynamic lift.
1.2 Falling Through Rising Air
Think of a leaf in the wind. In windy conditions, some of the wind is blowing
upwards, and the leaf rises. The leaf is still falling through the air, but the
upward speed of the air is greater than the downward speed of the leaf so it
1.3 Aerodynamic Lift
Some plants have evolved seeds with wings – the sycamore for example.
These leaves don‟t rely on rising wind to stay airborne, but on aerodynamic
lift, the dynamic part of the word implying, correctly, that movement of the
wing through the air is responsible for generating the lift.
A kite flies because it is tethered. In a wind it stays still, in a horizontal
sense, but the wind does not, blowing over its “wings” and giving it lift.
July 2008 Page 1 of 32
Release the string and the kite flies off at the same speed as the wind. There
is no longer any airflow over its wings and it crashes to the ground.
We all know that airflow over an aircraft‟s wings generates the lift. We also
know, as computer pilots or real pilots, that to keep an aircraft flying with
no power source other than the wind is quite easy. Simply point it down a
bit. Under the force of gravity, it will move through the air and the resultant
airflow over the wings generates lift. Unfortunately it will only fly
To make a glider fly without tethering it to the ground, or always going
downwards, both of which are a bit pointless, the forces we need are those
which will keep it airborne as long as possible. To continue on our leafy
theme - the leaf falls more slowly when it has wings, because nature‟s
intention is that it should, in this longer time span before hitting the
ground, travel further away from its parent.
So if the wind blows upwards, then the aircraft could still fly downwards,
relative to the wind, but relative to the earth it would fly level or even go up,
thus staying aloft longer.
The creator of the universe thought of that one, and provided us with two
sources of upward wind: -
a) Hills: - with their sloping surfaces facing towards the wind deflecting it upwards. It
gliding, this is called “Ridge Lift”.
b) Warm Air – air heated by the sun reflecting off the ground and hotter therefore than
the surrounding air, will rise. (Why it does so is not part of this document). In
gliding, these columns of warm air are called “Thermals”.
With upward flowing air, the problem becomes not one of how a glider flies,
but for how long – how big are these bodies of upward flowing air? Big
enough for gliding to be realistically achievable over long distances is
sufficient answer here I think.
1.5 I Wouldn’t Start From Here
You know the old joke – “If wanted to get where you‟re going, I wouldn‟t start
from here.” You can‟t just start gliding from the ground. You need
something to get the glider into the rising air in the first place. To get it off
the ground, it needs airflow over the wings until it can find the rising air.
We can push our glider off the top of a hill, and that is how the first gliders
were launched, but without a convenient hill of sufficient height and
sufficient steepness of slope, in the place we want it to be, we are stuck. We
could stand in front of the glider with a huge fan, but the moment it moves,
it loses that airflow, and running in front of it with the fan isn‟t practical
either. (Believe me the pioneers of flight didn‟t discount ANYTHING in their
search for the Holy Grail!).
July 2008 Page 2 of 32
To get a glider airborne initially, it has to be “launched” by either catapulting
it skywards or towing it there with a powered aircraft. Both methods always
seem to me like cheating, but it is a fact of gliding life.
1.6 Requirements For Flight Simulator
We are going to simulate gliding on a computer and that has the same
fundamental requirement as real gliders. Upward air flow. Microsoft have
blown a bit hot and cold over upward air flow over the years. It was
available in certain defined areas in the second version of the programme,
FS4, in 1991, but until FSX had been ignored. Unfortunately, the FSX
thermals are unrealistically powerful and extend to heights far above that
which pertains in the real world. So we have to use other tools.
Unfortunately, the research carried out by Richard and Maurice showed that
a quick flit to sample the difference between gliding and powered flight isn‟t
so easy. So it was agreed that this Manual should be as comprehensive a
guide for gliding in Flight Simulator as possible, but should be able to be
used equally satisfactorily for a simple one-off gliding event or for members
who want to take virtual gliding seriously. The Manual includes
instructions on how to create the correct computer environment for both
basic and advanced gliding.
There is quite a lot of information and software available for gliding, and it
would be prudent to keep it all in a separate dedicated „Gliding‟ folder on
your FS machine. We have researched a number of programmes and the
ones described in this document are the ones recommended by the Club.
2 BASIC GLIDING IN FS2004
This section of the Manual deals with a simple gliding installation for
FS2004. Using the recommended aircraft and lift generation software, you
can enjoy winch launches, flying circuits, and quite lengthy cross country
flights. The main difference from powered flight is, rather like musical
chairs, to ensure you can reach the next thermal for lift, or an aerodrome to
land. It can be quite exciting when either is not readily available!
2.1 The Download List for FS2004
Below is the list of the applications available for start gliding in Flight
Simulator 2004. They are all freeware, although a shareware version of
FSUIPC is also available which has many more features. The ones we will
be using in the Club are identified in bold red type in the paragraphs below.
They have been selected on the basis of ease of installation, ease of use and
good results. You can experiment with the others as you wish, but for our
events, it is preferable to use the same as everyone else.

Each of these is described in detail in sections 2.2 to 2.7 below.
Warning: Do not install any of this software until you have read Section 4 of
2.2 The Schleicher ASW28
There is one glider available, the Schleicher ASW28, that suits our
requirements for both FS2004 and FSX. It has the Cambridge Instruments
Glider Gauges (CAI-Set) gauges and winch launch facilities. Originally made
for FS2004 it works perfectly well in FSX including the winch launch facility.
You will find it at www.virtualsoaring.org
When you have opened the site main page, from the menu on the left select
DOWNLOADS then select AIRCRAFT then select FS2K4. Scroll down the
right hand page and you will see Schleicher ASW28 for FS2004. Click on
that phrase to download the glider.
The supplied zip fie can be safely placed in your main FS2004 folder and
unzipped. All the files will be extracted to the correct folder without any
further user action.
Note: This zip file will not install the aircraft correctly in FSX. See Section
3.2 for FSX installation.
Some people like to install files manually so they know exactly where each
file has been placed on their PC. If you prefer this option, unzip the archive
into a temporary folder and place the files as instructed in the included
2.3 FSUIPC3 for FS2004
This remarkable programme has been at the heart of Flight Simulator
activities for a very long time. It is highly unlikely that any active Cix VFR
Club member is unaware of it or has not got it installed. The freeware
version is capable of interfacing with all the general multiplayer software.
The shareware version is only necessary if you wish to use the additional
features such as key and joystick button mapping, creating individual
July 2008 Page 4 of 32
aircraft mapping profiles and logbook functions. It is really included here
Warning: The CCS2004 automatic install routine overwrites your
FSUIPC.DLL and FSUIPL.INI files if they exist on your system. It is probable
that the version of FSUIPC you have is newer than the one included in the
install, so it is essential that you make backup copies of these two files
before installing CCS2004.
2.4 Ridge lift for FS2004
We have not yet come across any tools for creating ridge lift in FS2004.
Ridge flying is possibly not of great interest to the Club as it involves flying
up and down the same piece of the country, and with a number of aircraft
all doing the same, could even be rather tricky. Perhaps that is its
challenge! However, the Club is not pursuing ridge lift capabilities at the
ASW28 at 9000 feet over Staffordshire
July 2008 Page 5 of 32
2.5 Thermals for FS2004
There are several applications for generating thermal lift, the simplest of
which are the two “blanket coverage” files available from AVSIM. They work
reliably and are a good introduction to gliding, but using them makes gliding
too easy, so for Club events, these will not be used.
Go to the AVSIM website and select the file library. Enter uktherm04.zip in
the Quick Search dialogue box and it should show an entry “UK and Ireland
Thermals” by Alejandro Villa. Download the file to your Gliding folder
Go back to the quick search and now enter England. zip and it should
show an entry “Whole England Soaring Scenery V1” by Francisco Augusto
Vargas Carneiro. Download the file to your Gliding folder.
These 2 sets of thermals if used together will give you almost continuous lift,
a utopian state for glider pilots, except when they want to land for a comfort
break, so beware.
UKTherm04 on its own provides good thermals, so that you can stay aloft
for a long time. They are not continuous, but are powerful. They start at
900 feet above ground level and extend to 15,000 feet. To land, just descend
to below 900 feet once close to the landing ground.
The England set will give you fewer thermals but used together with
UKThermal04 will give you plenty to think about. Possibly an excellent
starting position while you learn how to fly the aircraft, but then you too
might need a comfort break!
To install these files, just copy and paste the contents of each into its own
folder beneath your FS2004/Addon Scenery/Scenery folder. Don‟t forget
that the files must be in a sub-sub folder called Scenery within your
dedicated Sub-folder , e.g.
FS2004/Addon Scenery/UKthermals/Scenery and
FS2004/Addon Scenery/England thermals/Scenery.
Activate the scenery in the normal way, and then restart FS2004 in order to
recompile the scenery library index.
2.6 Cumulus 316
Cumulus 316 was created by the same writer as Cumulus X (see below)
which is a much more sophisticated application. Cumulus 316 creates a
“scenery file” e.g.thermal.bgl using a script file (e.g. thermal.cms,) which
contains the necessary parameters such as distance apart, centre of the
area in which the thermals will be generated, cloudbase altitude etc.
Cumulus 316 has to be run in a DOS window, and is best activated by
means of a “Batch” file. Batch files are executable text files with the .BAT
extension, which are used at Command line level to enter DOS commands.
July 2008 Page 6 of 32
At one time, batch files were used a great deal to automate the entering of
multiple command line instructions, but they are little used in the Windows
The process is cumbersome, so the Club is not planning to use Cumulus
316. That is not to stop others creating their own lift BGLs, but it avoids the
need for non-technically minded members to struggle with the instructions.
When a lift BGL has been installed (again, like UKThermals, in a folder
within the FS2004 Addon Scenery folder) then, unlike UKThermals,
Cumulus 316 adds a number of small cumulus clouds to your sky, which, if
you can position your glider under them, provide thermal lift. The thermal
is quite small, realistically so, so you need to be able to fly round in tight
circles to stay within it.
Thermals are only generated if the Flight Simulator clock is set to between
12:00 noon and 18:00, although the thermals at 18:00 are too weak to be of
practical use, and 17:00 is a more realistic end time.
2.7 Cross Country Soaring 2004
Cross Country Soaring 2004 by Eric Cardin for use in FS2004 is a lot more
sophisticated than Cumulus 316. It is available from
This is the application which the Club will use for FS2004 gliding. When it
is started, a parameter table is displayed which allows thermal conditions to
be customised. The settings are remembered by the programme for repeated
CCS2004 dynamically and randomly creates thermals throughout a flight
anywhere on Earth. It does not create BGL thermal files, but uses a
superior technique which creates thermals which lean automatically with
the wind, vary in strength and size, smoothly "expire", and smoothly taper
off in strength at their tops. They are surrounded by sink, and the thermal
vertical velocity profile is a smooth, sinusoidal one, making thermal entry
and exit more realistic than the abrupt jolts caused in BGL thermals. The
program allows you to customize thermal strength, size, and height by
setting out the parameters in a form as shown below.
You can create thermals in one of three ways
Create a Cumulus 316 cms file and then convert that to a BGL using Cumulus316
The comprehensive Manual which is included explains fully how to create
thermals using each method. One advantage of the scripted method is that
July 2008 Page 7 of 32
script files can be shared between members, and each member runs
CCS2004 and it behaves for each in the same way.
The CCS2004 Control Panel
The programme writes the settings in the table above to a file - ccs.ini. For
simplicity, this ccs.ini file will be issued to members for the first event,
which will be run in “Unscripted” mode.
When you Start FS2004, you need to start CCS2004 separately. To make
this task easy, create a desktop shortcut to the programme file which you
should find in c:\Program Files\CCS2004 as ccs.exe.
When you start the programme the Control Panel is displayed. Click on the
Button labelled “Exit and Launch Cross-Country Soaring. A message is
then momentarily displayed in FS2004 in the familiar red text on a green
banner just below the top of the screen.
Cross-Country Soaring - version 4.0. Initialisation complete.
After a few seconds, this disappears and so does the Control Panel. It is
now running in the background There is no evidence in Task Manager that
July 2008 Page 8 of 32
it is working, so t prove that it is working, simply press the “Cheat Keys”
<Tab>-W or <Tab> E which will give you a distance and bearing to nearby
thermals. The program stops only when you exit FS2004.
3 BASIC GLIDING IN FSX
3.1 The Download List for FSX
Below is the list of the applications available for start gliding in Flight
Simulator X. They are all freeware, although a shareware version of
FSUIPC4 is also available which has many more features. Initially, only
Cumulus X will be used for generating thermals, but Sim_Probe is too good
a programme to ignore and will be incorporated at a later date.

3.2 The Schleicher ASW28
The Schleicher ASW28, as mentioned in 2.2 above, suits our requirements
for both FS2004 and FSX. It has the Cambridge Instruments Glider Gauges
(CAI-Set) gauges and winch launch facilities. Originally made for FS2004 it
works perfectly well in FSX including the winch launch facility. You will find
it at www.virtualsoaring.org
When you have opened the site main page, from the menu on the left select
DOWNLOADS then select AIRCRAFT then select FS2K4. Scroll down the
right hand page and you will see Schleicher ASW28 for FS2004. Click on
that phrase to download the glider.
The supplied zip fie will not place files correctly in FSX. The Club has built
an FSX version, ASW28 Install FSX.ZIP which does install all the files in the
correct place, and this is available on the Club‟s web site in the Aircraft
section. Place this zip in your main FSX folder and double click the file
name. All the files will be extracted to the correct folder without any further
user action. Some people like to install files manually so they no exactly
where each file has been sent on their PC. If you prefer this option, unzip
July 2008 Page 9 of 32
the archive into a temporary folder and place the files as instructed in the
included Readme.txt file.
Some people like to install files manually so they know exactly where each
file has been placed on their PC. If you prefer this option, unzip the archive
into a temporary folder and place the files as instructed in the included
ASW28 and The Long Mynd GliderStation in the Horizon Photo-Scenery
3.3 FSUIPC4 for FSX
FSUIPC4 was created especially for FSX, and the basic version, freeware in
older versions, is built into FSX. A shareware version of FSUIPC4 is
available and is included in the download list in case you wish to purchase
it. Again, it is only necessary if you wish to use the additional features such
as key and joystick button mapping, creating individual aircraft mapping
profiles and logbook functions.
3.4 Ridge lift for FSX
This is described in Section 5, „Advanced Gliding‟.
July 2008 Page 10 of 32
3.5 Thermals for FSX
The Ukthermals04 files for FS2004 are supposed to work in FSX but we
were unable to get them to do so. The author has indicated to us that it is
possible that they won‟t work on every system.
CumulusX creates thermal lift in association with appropriate clouds either
randomly, with a wide variety of characteristics, or based on custom-tailored
lists of thermals. Both methods allow flying online, with the same
conditions for all participants. It adapts automatically and continuously to
the FSX internal weather conditions even in real-weather mode.
With the help of an additional slope database (not included), it produces also
widely varying ridge-lift conditions in large areas of the world. It tries also to
place thermals in mountain areas according to slope conditions and sun
irradiation. It also supports Sim_Probe.
The user can choose the difficulty level according to his/her personal skills
from very easy to realistic and difficult.
It works equally well with Windows XP and Windows Vista, but does require
Flight Simulator X SP2 to be installed.
Cumulus X is downloadable from http://www.luerkens.homepage.t-
Full web based instructions can be found at
These instructions are VERY comprehensive and you may find them a little
daunting. It is full of technical information, but Cumulus X is a lot easier to
run than the impression these instructions may give.
To install CumulusX, follow the installation instructions below
1. Make a safe copy of the file AirObjectVisuals.xml in FSX main
2. Rename ThermalDescriptions.xml file in the FSX main folder to
3. Extract the contents of CumulusX.zip to a folder in your Gliding
Folder named CumulusX
4. Copy the AirObjectVisuals file from the Gliding\CumulusX folder
to the FSX main folder, accepting the "overwrite" action.
5. Change Directory to Addon Scenery and create a new folder
July 2008 Page 11 of 32
6. Change Directory to "CumulusX".
7. From your Gliding\CumulusX Folder, copy the Scenery and
Texture folders to your new Addon Scenery\CumulusX folder.
8. Change Directory to \FSX\Modules - if this folder does not exist,
9. From the Gliding\CumulusX folder, copy the 2 folders from within
its Modules Folder to the \FSX\Modules Folder.
10. Change Directory to FSX\SimObjects\Airplanes\DG808S\Panel.
11. Copy the 3 files from the temporary CumulusX folder
CumulusX\SimObjects\Airplanes\DG808S\Panel to the
12. Close all open windows
13. Start FSX.
14. Add the "CumulusX" Scenery to the Scenery Library in the usual
July 2008 Page 12 of 32
CumulusX Settings Menu (Left) Operating Menu (Right) and
Thermal Generated Clouds
When you Start FSX, you need to start CumulusX separately. It is therefore
useful to create a short cut to CumulusX.exe on your desk top. Locate
CumulusX.exe in your <FSX>\Modules\CumulusX! folder; right click on its
file name and choose “Send To…” and then “Desktop (Create Shortcut)”.
Once CumulusX is running, changes can be made from within FSX via the
CumulusX Addons Menu
4 FIRST FLIGHT
The control of the aircraft is no different in FS2004 or FSX, and is little
different from any light aircraft. It‟s just quieter. The predominant sound is
the gentle sighing of the wind – very relaxing.
The preparations for flight are different, as is the software used to generate
lift, so follow the appropriate instructions below for your version of FS.
4.1 Preparation in FS2004
4.1.1 Install Cross-Country Soaring 2004
Before installing CCS2004, make a safe copy of your FSUIPC.DLL and
FSUIPC.INI which you will find in your FS2004 modules folder.
Install CCS2004. Copy the ccs.ini file provided by the Club to your CCS
programme folder C:\Programs Files\CCS 2004.
Delete the FSUIPC DLL and FSUIPC.INI files installed by CCS2004 and
replace them with your own safe copies.
4.1.2 Install the Aircraft
If you have not already done so, install the Schleicher ASW28 to your Flight
Simulator 9\Aircraft folder.
July 2008 Page 13 of 32
4.1.3 Suppressing Error Messages
Load Flight Simulator as usual. FS2004 will display two error messages
when loading: -
You can safely click “Yes” to each of these messages.
This happens because some gliders include non-standard gauges (including
the CAI-set Gauges in the ASW29 we have chosen as the starting aircraft).
You can suppress these messages by entering the following in your
FS2004.CFG config.file. This file can be found in:
C:\Documents and Settings\<Your Username> \Application Data\Microsoft\FS9
In Windows XP
C:\Users\<Your Username>\AppData \Roaming\Microsoft\FSX
In Windows Vista
You may wish to save a copy of the unedited fs9.cfg file first. A simple way
to do this is to copy it into the same folder. The new file will be
automatically named by windows Copy of FS9.cfg
Now open FS9.cfg with Notepad and add, at the bottom of the file, the
following lines: -
July 2008 Page 14 of 32
Save the file with the changes.
These lines prevent the warnings from being displayed, but do not stop the
aircraft‟s gauges from working, nor do they affect any other aspect of
FS2004, so you can safely leave them there even if you no longer wish to do
any gliding.. However, the instruction to add these lines is included in most
other glider installation instructions, so should be left in, should you decide
to pursue gliding further.
4.2 Preparation in FSX
4.2.1 Install CumulusX
If you haven‟t done so already, install Cumulus!X.
4.2.2 Install the Aircraft
If you have not already done so, install the Schleicher ASW28 to your
Flightsimultaor X\SimObjects/Airplanes folder.
4.2.3 Error Messages
The error messages generated by FS2004, caused by two modules contained
in the ASW28 glider package, do not occur in FSX. That is one problem less
that you have to worry about.
4.3 Introducing the ASW28
Lined up on Lasham’s 09
July 2008 Page 15 of 32
Start Flight Simulator and create a new flight, selecting any one of the three
Schleicher ASW28 models you have already installed. In FSX it will show as
a “grey” „plane with a question mark over it in the Aircraft Selection menu
page, as there is no thumbnail image included in the package. You can
always add one later if you wish, as follows. Create a screenshot of the
glider in flight, save it in jpg format as thumbnail.jpg, resize it to 838 pixels
wide by 419 pixels high and place it in the texture folder of the aircraft.
Select a known gliding airfield, such as Lasham or Shobdon and click “Fly
now” You should find yourself on the active runway in the 2D cockpit view.
Cycle the views to see the different options and return to the 2D cockpit view
for now. In flight, the 3D cockpit view will probably be preferred.
Note: If you are going to connect to VATSIM, you will have to carry out the
following procedure before connecting.
1. From your position on the active runway, slew sideways to position your glider
on the grass at a reasonable distance from the runway.
2. If there is an alternate parallel grass runway you can use as there often is at
Glider aerodromes, use that.
3. Connect to VATSIM
4. Check for other traffic. If there is none in your vicinity, slew back onto the
runway and carry out the winch launch described in 4.4 below.
5. If there is other traffic, wait until it is clear before carrying out 3. above.
6. If there is active ATC on the aerodrome, advise them of your intentions and
request that they allocate you a 3 minute “slot” in the traffic pattern to launch.
(Slewing back into position when fully ready and triggering the winch launch
takes less than 1 minute.)
7. If there is no active ATC, advise the other aircraft by text message that you are
about to commence a glider launch and advise that you will carry out your
launch immediately after they are airborne and before their next landing.
4.3.1 The Navigation Instruments
We need to work round the instrument panel now, so that you know what
everything does. Most obvious are the two LCD screen instruments in the
centre of the panel. These are complex navigation instruments designed for
competitive gliding coupled with a GPS and a glideslope indicator which tells
you whether you are high enough or too low to reach your next waypoint.
This will be fully described in section 5 of this manual.
The standard Garmin GPS is available in the ASW28 glider and may be used
for navigation in the usual way. It is selected and deselected by pressing
Shift-5 on the keyboard
July 2008 Page 16 of 32
For the moment, however, we are going to completely ignore these
instruments except to switch on the lower one by clicking on its ON button.
Make sure the mouse pointer hand has a „+‟ sign against it when you do
The ASW28 panel – ready to launch
4.3.2 The Magnetic Compass
The top left instrument is a magnetic compass. If you aren‟t used to flying
by means of a compass (as opposed to a gyroscopic direction Indicator) you
are in for a bit of fun, for the compass seems to have a mind of its own.
Fundamentally it only points in the right direction when you are straight
and level and at a steady speed. These are conditions not often experienced
in gliding! To have any hope of pointing in the direction you want to go,
remember one simple rule.
Roll out of turns BEFORE the heading that you want to fly appears in the
compass window when turning from west to north or east to north, and roll
out AFTER the heading you want when turning from west to south or east to
south. When turning towards east or west, you can roll out on the heading
July 2008 Page 17 of 32
indicated. In aviation, this behaviour is given a mnemonic, as everything
else in aviation seems to be.
UNOS which stands for Understeer North; Oversteer South
There is a full tutorial on using a magnetic compass on the Club web site.
The link is at the bottom of the Downloads/Miscellaneous page. The tutorial
describes a different type of compass to that fitted to the glider, but the
behaviour is the same.
4.3.3 The Variometer
This is probably the most important instrument in a glider. It is similar to
the Vertical Speed indicator in most powered aircraft. Fundamentally,
Needle pointing up - Good; Needle pointing down - Bad!
Unsurprisingly gliders glide well. So when you aren‟t getting thermal lift,
and if you are flying more or less level at cruising speed, the variometer
needle only points down a little. In the ASW28 as in many gliders, it is
calibrated in knots rather than feet per minute. A typical “good” glide value
is 2 knots, which is about 200 feet per minute. You can watch the altimeter
creeping down so very much more slowly than in a powered aircraft when
you close the throttle. So if you can get yourself up to about 2000 feet you
can fly for about 10 minutes before the ground starts to look very close.
In a good thermal, you can get lift rates of 5 or 6 knots in Flight Simulator,
so you can soon reach respectable altitudes and fly considerable distances.
The musical chairs analogy returns, because your plan is to fly from one
thermal to another until you reach your destination or have had enough
flying for one session.
4.3.4 Air Speed Indicator
This needs little explanation. There is a small yellow pointer at 42 knots
which is the minimum safe speed. This aircraft stalls very suddenly at
about 35 knots. The audible stall warner goes almost simultaneously with
the sudden pitch down, so the yellow pointer is important.
The altimeter is a 3-needle type, not often seen in modern powered aircraft.
It indicates up to 20,000 feet. The Kohlsman subscale is in hectopascals
(the same as millibars), but unfortunately isn‟t easily readable.
4.3.6 Attitude Indicator
This has a quirk which is probably realistic – I‟d need a real world glider
pilot to tell me, but if you don‟t set wings level before starting the launch,
then the AI will not indicate properly, but appears to topple in level flight.
To ensure wings level before start, press the slew key („Y‟) twice slowly.
July 2008 Page 18 of 32
4.3.7 Turn and Slip
Do you know the old adage “You can tell a Cessna pilot because he doesn‟t
use his feet” ? Small Cessnas have “washout” in their wing profile, which
eliminates much of the adverse yaw which occurs when an aircraft banks
into a turn – it tries to keep going straight on. Gliders do not have washout,
and because of their very long wingspan, have significant inertia in yaw. In
gliding, you MUST keep the slip ball in the middle – the aircraft in balance,
or you will be in trouble. A spin is never far away in a glider. Unfortunately,
from my limited tests, the ASW£29 in FS doesn‟t want to even hint at
spinning if you force the aircraft out of balance.
My first reaction to this instrument was “why have I got a fuel gauge”? This
indicates the state of a tank of water, which is filled for launch, but can be
jettisoned as required in flight. It is similar to the sandbags traditionally
dropped by balloonists, and the idea is simply to lighten the aircraft to
prolong the flight. The way ballast is managed in gliding will require a real
world glider pilot‟s input here. For now we can ignore ballast. It is amusing
though to click on the tap and listen to the ballast tank empty. To fill the
ballast tank click near the „F‟ on the scale.
There is a COM radio for use on Vatsim if required. It is accessed by keying
Shift-4. It replaces the ballast gauge. Shift-4 again hides the radio. The top
knob is an On/Off switch, the left hand switch cycles through 4 preset
channels. The right hand knob changes the frequency of the currently
selected channel. Click near the knob to change the decimal values and
further away from it to change the whole digits.
4.3.10 Air Brakes
The blue handle on the left sidewall of the cockpit controls the air brakes.
You can drag the lever with the mouse, set it as a control lever instead of the
throttle, if you wish, or press „/‟ to activate and de-activate. The former two
methods allow gradual deployment, the later is “all or nothing”. When
coming in to land, using air brakes is essential if you do not wish to float on
for ever 2 feet above the runway. Approach the landing area very much
more steeply than in a powered aircraft and deploy the air brakes as you
dive for the runway. The air brakes will control your speed very well. As
you flare, lift and speed decay very rapidly, so be sure not to flare too high!
4.4 The Winch Launch Device
In FSX, an aerotow feature has been included for launching gliders, but
prior to FSX there was no glider launching procedure other than slewing to
altitude and then starting off. Now some clever software writers have
created a realistic winch launch system for both FS2004 and FSX, which
July 2008 Page 19 of 32
improves the realism of gliding at least 100%. It is actually (Shhh!) an
invisible jet engine.
On the glider panel you will see a green lamp, with a switch on its left. This
is a cunning winch launch device – I would hardly really call it a gauge. To
open the device for use, press [Shift-2] on your keyboard. This opens a
small window in which you can select the winch launch height. It is preset
to 1500ft above the aerodrome level, but by clicking on the up or down
arrows you can alter this in 33.33ft steps from a minimum of 1000ft to a
maximum of 2000ft.
4.5 Off You Go
4.5.1 Set the Season and the Weather
Set the time of day between 1200 and 18:00 BST in Summer.
Ensure that "Weather Settings" in FS has a "wind component" [e.g. 8
Knots (Light Winds) from the west or southwest].
Select "Fair Weather" from the Weather Tab [this ensures the 8 Knot
component is added to the Weather].
In FSX (only), ensure that Thermal Visualisations is set to "Natural"
within the Weather tab of Options\Display.
4.5.2 Find a Thermal and Keep It
Start at Henstridge [EGHS], Runway 25 at 1.00p.m. on a summer‟s
afternoon to give yourself the optimum conditions for gliding to make it a
little easier to learn this discipline.
Using the Winch Launch device, set the launch to 2000 feet and launch.
Slow the Aircraft to about 60 knots and fly a rectangular circuit as you
would in a powered aircraft, watching and listening to the variometer. The
variometer should indicate a 2 knot down glidepath when you are not in a
thermal. This is the best glide performance. The variometer will start to
“twitch” when you are close to a thermal, and the needle will start to rise.
As it passes the zero point you will hear the (familiar to real world glider
pilots) "bip bip bip" song that we are after which indicates rising air.
Immediately after you pass the "variometer maximum up" point, turn
sharply left - it may be quite a steep "angle of bank" – usually at least 45o. It
can be helpful to watch the lower wing tip frequently to try and stay in the
right place relative to some ground feature. With practice you can centre
yourself in the thermal, drifting downwind with the cloud and gain at least a
thousand feet in height in just one thermal, although you might end up a bit
giddy from going round and round in a steep turn for several minutes.
Thermals are [simplistically] "holed doughnut" in shape, where the centre
[the hole] is where the "sink" exists, so stay away from there.
July 2008 Page 20 of 32
When you lose the lift, look upwind with respect to your "start" position and
"do it all again". Our researcher and retired glider pilot, Maurice managed
to find a "good looking" cloud which gave him "8 up" for several minutes, but
he was banked over to about 60 degrees because the lift zone was narrow -
it gets wider but less powerful as you go up. There was enough lift in one
cloud to give him a shade over 3000 feet above his start height before he lost
You need to fly more quickly "between thermals" and "as slow as you can go"
when in a thermal. The yellow arrow marker on the Airspeed Indicator is a
safe minimum speed. (Stall speed is considerably lower). The typical glide
ratio has been estimated from observation in both FS2004 and FSX at 100
feet per mile, but don‟t rely on this.
4.5.3 How Far Can I Go
For your first few flights, stay close to your launch airfield, so that you can
land back. Abandon any attempts to find thermals below 1000 feet above
ground level. At 2 knots sink rate (200 feet/minute almost exactly) you have
just 5 minutes to touchdown from 1000 feet without spoilers. At 60 knots
airspeed this is 5 miles. Thus your glide ratio calculates (in ideal conditions)
as 200 feet per mile. Within the range 40 to 60 knots airspeed, the rate of
descent doesn‟t vary much in the FS ASW28, so you have some leeway in
the distance you can safely be from the landing point when you are just
1000 feet above the ground.
It is undignified to “land out” requiring the recovery team to come and
dismantle the glider to take it back to the airfield. It could cost you a lot in
drinks at the bar! So to make sure you land back on the airfield, stay close
until you have gained experience.
Flare very late, and remember, if you have retracted the mainwheel, to lower
it again please. GRP fuselages don‟t like being scraped along the ground.
Remember too, that without an engine, the energy equation is very simple.
You can convert height into airspeed and vice versa almost at will within the
glideslope envelope. This can work against you when landing, so you have
to get the energy equation just right. If you are too high on approach and
increase your rate of descent by lowering the nose, you WILL go faster.
Raise the nose to slow down and you WILL climb. The only tool you have to
change this is the spoilers. Get too low on approach and you have a minute
or so to contemplate the cost at the bar! Exactly as in a powered aircraft, no
attempt to stretch the glide will ever succeed (unless of course you were
approaching too fast and can convert some of that excess kinetic energy into
Use the "spoilers" (Press „/‟ to deploy and retract them] to slow down and
reduce the wings remarkable efficiency for landing, other wise you will float
for ever. The spoilers are very powerful and your descent path will be very

steep with them deployed, so deploy them only when on final and very close.
Like flaps on a powered aircraft they should not be retracted after
deployment until you are safely on the ground.
5 ADVANCED GLIDING
For the initial gliding event being held by the Club, you need go no further.
The foregoing is all you need. If you want to more into more advanced
gliding then read on
There is a whole world of Flight Simulator gliding activity out there. The
tools described in this section allow for complex flight planning, use of
sophisticated gliding instruments and flight logging.

5.2 The Cambridge Instruments Gauges
This set of sailplane gauges for FS is based on the set of Cambridge
Instruments gauges used in many real sailplanes
This section describes how to use these Gauges known in the FS Gliding
world as the CAI-Set gauges. These are specialised instruments which are
fitted in the Schleicher ASW28 Glider and others and provide navigation
information for cross-country and competition gliding. They are models of
the real world instruments made by Cambridge Instruments Ltd., which
carry out the same functions. These FS gauges are a joint venture between
Roland Stuck (a real world glider pilot) and Max Roodveldt.
The real GPS-NAV is a navigation computer as well as a flight recorder. In
this FS version, only the navigator function has been reproduced which
allows the glider pilot to navigate to any of the 250 waypoints held in the
internal database. Like the original instrument, the virtual GPS-NAV works
with a database in the Cambridge „.dat‟ format. (Such files are available on
July 2008 Page 22 of 32
the internet on several real-world gliding sites, and are used for
competitions etc., but we don‟t need to pursue that).
In FS, the GPS-NAV is used to fly a route comprising a series of turning
points (called a task in real gliding). Tasks can be composed using the
original Cambridge Instruments computer program. (Details later).
The L-NAV is a glide computer which calculates the optimal speed to fly
between two thermals as a function of glider performance (known as the
„Speed Polar‟ of the glider) and the expected lift (The so called MacCready
setting). It also calculates the altitude required to reach any point which is
in the GPS-NAV database (both instruments are coupled) as a function of
glider performance, wind component and MacCready setting.
The Compensated Electrical Variometer (CAF) is controlled by the settings of
the L-NAV. It can either be displayed as a 80 mm or a 60mm diameter
gauge on the panel – depending on the space available in the glider panel
The ASW28 Panel with CAI-Set gauges
July 2008 Page 23 of 32
Because the real instruments are rather complicated - especially the L-NAV,
only those functions that are useful within FS are implemented.
The GPS-NAV Instrument The L-NAV Instrument
5.2.4 How to use the GPS-NAV
The Cai-set GPS-NAV has to be programmed with a flight in the same way
as a standard real world GPS. The FS GPS is programmed atomatically
when you create an FS Flight Plan. Programming the Cambridge
Instruments GPS-NAV is somewhat complex and is described fully in
Section 5.7 below. For the moment, we will assume that the unit is
programmed with a flight starting and ending at Long Mynd (Midland
Gliding Club glider station).
In the cockpit, switch on both the L-NAV and the GPS-NAV. The GPS has 6
buttons. There are 2 at the top, ON and GO, 4 at the bottom, each with an
arrow, LEFT, RIGHT, UP and DOWN, referred to in the instructions below
simply as (e.g.) „Click RIGHT‟ meaning click the RIGHT arrow.
NOTE: Do not switch the GPS-NAV off when in flight otherwise the
flight will not be recorded in full.
Flying a Task from Long Mynd
When you first switch on the GPS-NAV, it will display Arrival Mynd.
Click on the RIGHT button until you get to Task Selection.
Then click GO.
It will then display Task Selection A
RIGHT click till you see Turnpoint A0 CVN Crvnarms
You will see Task A Declare NO
NO turns to YES
July 2008 Page 24 of 32
It will display Start A Task NO

Click GO to Here
You will then see ON Task TP CVN Crvnarms
You will now see an arrow pointing to the right, the direction you have to
turn after launch.
The bearing is 162o
TRK is as yet NIL
Distance is 9.2nm
You can now launch and follow the directions as given in the GPS-NAV.
When you get to 2 nautical miles from the CVN turn point you will get the
message Close To
Note: in FSX this may not be until you get to 1 nautical mile from your turn
When you get to the turn point you will get the message Arrival
When you arrive at the turn point click RIGHT on the GPS until you see
Task TP A1 SPT Shipton displayed
It will display ON Task TP 1 SPT Shipton
Follow the directions indicated by the GPS-NAV.
Repeat this procedure for the other turn points until you get back to Long
Land and get some help to tow your glider back to the hanger.
For the Flight Recorder programme, members only need to know how to
retrieve the data from the GPS-NAV and NOT how to programme it. That
can come later if necessary.
Note: This instrument is designed for more advanced gliding and will not be
used in the Club‟s initial gliding event.
The L-NAV will give you the following information.
July 2008 Page 25 of 32
At the bottom you will see either TW or HW these stand for Tail Wind and
The most important bit is the Glide Slope indicator.
It is on the right and is represented by an aircraft floating above, below or on
a horizontal bar.
If the aircraft is above the line then you have sufficient height to reach your
turn point or your destination.
If it is below the line then you are too low and you need to look for a thermal
or 2, but don‟t worry too much because if you are using both sets of
thermals in FS2004, as described in Section 2.5, it won‟t be long before you
5.3 TP Select
TP select is a tool for searching for and selecting British Gliding Association
official turning points. (TP stands for Turn Points if you hadn‟t guessed.)
TPSelect may be downloaded from
To install TPSelectJust double-click on the self-installing image you
downloaded and follow the instructions to install the program.
To remove the program from your computer, go to Add/Remove Programs in
Control Panel and click on the TpSelect entry
5.4 Flight Viewer [Recorder]
Go to www.fsglider.de from the left hand menu until you find “Tips and
Tricks English”. Select this option to show a series of questions and
answers. (As an aside, these are all worth reading.)
One of the questions is
FS shuts down when I switch on the GPS Unit
The solution it gives is to download Max Roodveldt‟s FSXwever Viewer
Program which records your flight. Because the original site has gone down,
we have made these three files available on the Club website. Look in the
Downloads/Software page in the Gliding area for
Flight_Viewer manual.zip, and
CAI-sets Instruments manual.zip
To install Flight_Viewer, Extract the zip file to its own folder in your Glider
The following files are included in the zip file.
July 2008 Page 26 of 32
SOARRec.dll - a module to record the flight
mr-caiset.gau – The Cambridge Instruments Gauges set
FSZweverview 2.exe - The programme (with an odd icon!)
LNAV_Polarlist.dat - a polar list [don‟t worry about this]
LNAV_Polar.dat - the result of a test flight
All the above files except FSZweverview 2.exe should already have been
installed as part of the ASW28 Glider installation.
Put the FSZweverview 2.exe file in your main FS2004/X folder.
Note: If you are going to use both FS2004 and FSX then the flight viewer
MUST go into both sims. You will then have to programme each sim with its
appropriate viewer. You cannot send data to FSX with the viewer that is
installed in FS2004 and vice versa.
5.4.1 Flight Data Handling
The GPS-NAV,- Flight Recorder and TPSelect work together to plan, fly and
record a flight. This is particularly valuable in competitive gliding.
5.5.1 Installing Sim_Probe
Sim_Probe, maps the terrain mesh in FS and diverts the wind accordingly.
It is built into CumulusX, and is selectable on or off from the main menu.
Sim_Probe is downloadable from
Sim_Probe creates ridge lift in FSX by detecting the underlying terrain in FS.
It is not needed for the first Club gliding event. Included in Sim Probe is the
Microsoft 2008 C++ Runtime Library vcredist_x86. We recommend that
you DO NOT use the one provided, but if the program does not run properly
go to the Microsoft site and search for, download and install the latest

can drag this bar lower down the page if you prefer.
6. Sim_Probe creates a log file in a standard International Gliding
Commission (IGC) format. The IGC log files are saved as <tail
number>_<date>_<time>.igc in the folder of your choice. The file is
saved at he completion of any of the following events:
when you complete a mission (succeed or fail)
when you land
when you exit a free flight
when you click the "add-ons".."sim_probe".."save IGC file"
5.5.2 Locations of exe.xml in Windows XP and Windows Vista

5.5.3 Ridge Flying with Sim_Probe
Trials of Sim_Probe have not yet been carried out. Therefore this section will
be completed at a later date.
5.6 Creating A Gliding Task
In gliding, building a flight plan into the GPS-NAV (note; NOT the standard
FS Garmin 285 unit) is a little complex. However if you take the following
section one step at a time, it is no more daunting than creating a flight plan
in FS itself. It is just that there are a few more steps.
5.6.1 British Gliding Association Turn Points
These need to be downloaded so that we can select those we need for our
flights. They are available in a number of formats. The Club has selected
two of the options.
The Excel File
The BGA has defined a large number of turning points (waypoints) for
various purposes including competitions Pilot Qualification routes, etc.
These can be used in the GPS_Nav gauge described above.
We need to know where all these British Gliding Association official turning
Click on this link www.spsys.demon.co.uk/waypoints/2008.xls and it
should bring up an Excel spread sheet with all the turning points. Save this
to your gliding folder.
There are, I think some 43 pages so you may NOT want to print it out but
just refer to it.
If you do not have Excel there is a free download of an Excel Viewer available
from the Microsoft download page http://office.microsoft.com/en-
us/downloads You may have to type „viewers‟ into the search tab.
There is also another way to find the turning points and that is by using
Google Earth. Needless to say you must have Google Earth installed.
Google Earth Method
Go to www.spsys.demon.co.uk/turningpoints.htm
From the left hand menu. select „Files for Downloading to Flight Recorders‟.
In the box at the bottom of the page, select “All of England,Wales and
This will take you to a page entitled “Worldwide Soaring Turnpoint Exchange
Unofficial Coordinates for the BGA Control Points”.
Scroll down to the bottom of the page and you will see a series of Icons.
July 2008 Page 29 of 32
Third line down and 4th icon from the left and you will see the Google Earth
Click on this icon and you will get the run or save option for bga2008a.zip.
Save it to your glider folder. Open the zip and extract the single „.KML‟ file.
Double click this to open it and Google Earth will start and display a long
list of turn points.
I suggest you save these in the way Google Earth advises.
5.6.2 Building the ‘Task’ with TPSelect
It is recommended that you create desktop shortcuts for both TPSelect and
the Flight Viewer application FSZweverview 2.exe, which is referred to in the
following instructions as just „Flight Viewer‟.
Remember that in gliding a „Task‟ is a course to fly comprising a number of
turn points. We need now to create our Long Mynd Task. For the initial
Club gliding event, this will be done for you, but it is described here so that
you understand what is going on.
Using whichever method you prefer select a start point.
For this exercise I am going to start at Long Mynd which is listed just as
You will see that there is lot of information given in the Excel spread sheet
which you can peruse at your leisure. It isn‟t essential for our initial flights.
Click on the browse button and you will see a list of all the BGA turn points.
Scroll down the list to find MYN and press Enter. You will also be able to
see the co ordinates of MYN.
Set The Range
You can enter whatever range you wish but bear in mind that the bigger the
range the more turn points will be selected.
For this exercise enter 20 and you will see that there are 29 turn points
within this range.
Review And Save
Select review and a list of all the turn points within the range we have set
will be displayed.
All the gliders use the CAMBRIDGE instruments so select Cambridge from
July 2008 Page 30 of 32
Click Save Turn Points. Save them in your glider folder along with
everything else. Name the file to something obvious and relevant, e.g.
Select the Turn Points From the Range
NOW open Flight Viewer (from your desktop shortcut if you have one), and
from the top menu select Load and then Any *.DAT File. Navigate to where
you saved your TPSelect file (LongMyndTrial.dat in our example), click on it
then select Open.
A screen is displayed showing 29 numbered circles and a list of the turn
points on the right which we selected in TPSelect.
Now from the menu select Task and then New.
In the top left hand corner of the screen you will see a list in red, headed
From the list in the right hand menu double click on No. 5 Craven Arms
and it should then appear as task selection No. 0, which is your first turn
point after leaving Long Mynd. Also, circle number 5 will turn red.
Now double click in turn numbers 5, 18, 4 and again 13 from the list in the
right hand menu. In the task selection list you will see that each leg now
has a distance with a total at the bottom. If the distance is in shown in
kilometres (Km) then click the Union Flag Icon and the distances will be
displayed in nautical miles (nm).
So our planned flight (Task) will be Long Mynd – Craven Arms – Shipton –
Condover and back to Long Mynd; a total distance of 27.3nm.
Send the Task to the Glider’s GPS-NAV
In Flight Viewer, from the top menu, select Send and then GPS-NAV.
You will see a message asking if you want to use this file: Click OK.
The course will now be installed in the GPS-NAV of your glider.
Your Recorded Flight
After you have landed and are safe then open up the Flight Viewer.
Go to LOAD in the top menu and select From GPS-NAV and a screen will
appear with your flight details.
To zoom in and out, turn off NUM-LOCK on your keyboard and use the
numeric keypad – [minus] and + [plus] keys.
Please note that the GPS-NAV , LNAV Polar and LNAV polar list files are
placed by the unzip process in the main FS2004 of FSX folder.
If you already have these installed then make a back up of the existing files
before installing these.
