72 // David Megginson made a few (mostly minor) mods to the LaRCsim files, and
73 // it's now possible to choose the LaRCsim model at runtime, as in
75 // fgfs --aircraft=c172
79 // fgfs --aircraft=uiuc --aircraft-dir=Aircraft-uiuc/Boeing747
81 // I did this so that I could play with the UIUC stuff without losing
82 // Tony's C172 with its flaps, etc. I did my best to respect the design
83 // of the LaRCsim code by staying in C, making only minimal changes, and
84 // not introducing any dependencies on the rest of FlightGear. The
85 // modified files are attached.

100 // Removed some printf()'s.
101 // Fixed the autopilot integration so it should be able to update it's control
102 // positions every time the internal flight model loop is run, and not just
103 // once per rendered frame.
104 // Added a routine to do the necessary stuff to force an arbitrary altitude
106 // Gave the Navion engine just a tad more power.

117 // Lots of little tweaks to fix various consistency problems discovered by
118 // Solaris' CC. Fixed a bug in fg_debug.c with how the fgPrintf() wrapper
119 // passed arguments along to the real printf(). Also incorporated HUD changes
120 // by Michele America.
