They are not now expected to be in any particular order, nor are they given specific names. The layout is somewhat free form. A questions is, how do you set up the gear model to support animation when you may want to model things as varied as a 747, a C-172, a P-51D, a Harrier, etc.?
Maybe we should do the same as we did for the braking group, define a left (most), right (most) and nose gear compression and let the animation derive any values from that?
Thinking about it again I think the solutions (for JSBSim) is quite simple, use the name of the entry (in lower letters) to define the gear:
AC_GEAR NOSE -6.8 .0 -20.0 1800 600 .5 .8 .02 STEERABLE NONE 10 FIXED
AC_GEAR L_MAIN 58.2 -43.0 -17.9 5400 1600 .5 .8 .02 CASTERED LEFT 0 FIXED
AC_GEAR R_MAIN 58.2 43.0 -17.9 5400 1600 .5 .8 .02 CASTERED RIGHT 0 FIXED
AC_GEAR TAIL_SKID 188.0 .0 8.0 20000 1000 .2 .2 .2 FIXED NONE 0 FIXED
AC_GEAR LEFT_TIP 43.2 -214.8 59.4 10000 2000 .2 .2 .2 FIXED NONE 0 FIXED
AC_GEAR RIGHT_TIP 43.2 214.8 59.4 10000 2000 .2 .2 .2 FIXED NONE 0 FIXED
/gear/nose /gear/l_main /gear/r_main /gear/tail_skid /gear/left_top /gear/right_tip
The only change might be that YASim should allow for defining named gear locations.
