    To run, try:

    fgfs --aircraft=beech99-v1-uiuc

    Files and directory structure required in $FG_ROOT/Aircraft/ to fly the
    model:

    beech99-v1-uiuc-set.xml
    beech99/Sounds/uiuc/beech99-sound.xml
    UIUC/beech99-v1/aircraft.dat

    These files above come with the FlightGear base package.

    Files and directory structure required in $FG_ROOT/Aircraft/ to see the
    external 3D model:

    beech99/Models/uiuc/beech99/beech99.ac
    beech99/Models/uiuc/beech99/beech99.air
    beech99/Models/uiuc/beech99/beech99.loc

    These files can be obtained from Wolfram Kuss' website here:

    http://home.t-online.de/home/Wolfram.Kuss/

    The 3D model is here:

    http://home.t-online.de/home/Wolfram.Kuss/FGFS1/FGFS1.htm

    Download the zip file and model files in the directory indicated
    above.  Under linux, the files from zip archive might need to be
    renamed to lower case (if they are not already that way).  Renaming to
    lower case will be necessary if FlightGear crashes when trying to read
    the texture files.

    To use the new aircraft model and not the default Opus glider, edit the
    beech99-v1-uiuc-set.xml file and change the string:

    "Aircraft/UIUC/Models/opus/opus-model.xml"

    to

    "Aircraft/beech99/Models/uiuc/beech99/beech99-model.xml"

    after the model files have been installed.

    Model description and updates:

    5/25/02 - First release: v1

    * "Linear model" meaning that constants are use for stability
      derivatives.  The chief drawback of this type of model is that stall
      is not properly modeled, and as a consequence an unrealistically
      high lift coefficient is produced when the aircraft is at a high
      angle of attack.  As a result the aircraft can fly much more slowly
      than in real life.

    * Model largely built from: "Small twin turboprop commuter airplan"
      data from: Roskam, J., Airplane Flight Dynamics and Automatic Flight
      Controls, Part I, DARcorporation, Lawrence, KS, 1995, pg 508-510.
