      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:
               Hot air,
               Upward wind
               Aerodynamic lift
               Reactive thrust
      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
      stays up.

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

1.4   Gliding
      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.

      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.

      CCS2004 for FS2004    

      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
      this manual.

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
      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
      Readme.txt file.

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
      for completeness.
      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 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
               Unscripted
               Scripted
               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

      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.


3.1   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

      correct place, and this is available on the Club‟s web site in the Aircraft

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

3.4   Ridge lift for FSX
      This is described in Section 5, „Advanced Gliding‟.

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.

3.5.1 CumulusX.
      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 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
                 named "CumulusX".

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,
                  create it.

            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
                  FSX\SimObjects\Airplanes\DG808S\Panel Folder.

            12.   Close all open windows

      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
      Addons Menu.

      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
      Or in
      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.

4.3.5 Altimeter
      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.

4.3.8 Ballast
      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.

4.3.9 Radio
      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.

4.5.4 Landing
      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
      potential energy.
      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

July 2008                                                               Page 21 of 32

      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.

      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.

5.2.1 GPS-NAV
      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).

5.2.2 L-NAV
      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.

5.2.3 CAF
      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

      Because the real instruments are rather complicated - especially the L-NAV,
      only those functions that are useful within FS are implemented.

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
            Click GO
            You will see Task A Declare NO
            Click DOWN
            NO turns to YES

July 2008                                                           Page 24 of 32

              Click GO
              It will display Start A Task NO
              Click DOWN
              NO turns to YES
              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
              Click GO
              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.

5.2.5 L-NAV
      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
      Head Wind.
      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
      hit one.

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 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, and
      CAI-sets Instruments
      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   Sim_Probe

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
            1. Unzip the file to a “Sim_Probe” folder in your
               Gliding folder.
            2. Copy the Contents of the gliding\Sim_Probe\Modules folder to your
               FSX Modules folder. You should end up with “Microsoft Flight
               Simulator X\Modules\sim_probe\sim_probe.exe"
            3. Copy the Contents of the gliding\Sim_Probe\SimObjects folder to
               your FSX Simobjects folder. You should end up with “Microsoft
               Flight Simulator X\SimObjects\Misc\SimProbe "

July 2008                                                                Page 27 of 32

            4. Add sim_probe.exe to your FSX autostart file exe.xml. The "exe.xml"
               file can be found at the locations shown at the end of this list of
            5. Start FSX, and you should see a new item – Sim_probe in your "Add-
               ons" menu. The sim_probe "show status text" will display the ridge
               lift sim-probe is calculating in a green bar at the top of the page. You
               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"
                        menu item

5.5.2 Locations of exe.xml in Windows XP and Windows Vista

              "<Drive>:\Documents and Settings\<username>\Application
      Windows Data\Microsoft\FS2004\exe.xml"
      Vista           <Drive>:\Users\<username>\AppData\Roaming\Microsoft\FS2
      Note that the "Application Data" or "AppData" folder is 'hidden' by default in
      Windows and you might have to go your"<Drive>:\Documents and
      Settings\<username>" folder and select Folder Options-> "Show hidden files
      and folders" to be able to access it.
      The text to add at the bottom of exe.xml is
                 <CommandLine>log="C:\\Documents and
      Settings\\<Username>\\My Documents\\ Flight Simulator
      Open exe.xml in Notepad and copy and paste this fragment from here. Don‟t
      forget to change <username> to your actual user name.

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
      points are.
      Click on this link 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
      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
      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

      Icon             .
      Click on this icon and you will get the run or save option for
      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.
      Open TPSelect.
      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.
      File Format
      All the gliders use the CAMBRIDGE instruments so select Cambridge from
      the list.

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
      Task Selection
      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.
