I've done a little more work on YASim initial velocities, and the --vc and --mach options should now work more-or-less correctly (except that --vc doesn't take compressibility effects into consideration). That means that you can start YASim models in the air the same way as you start JSBSim and UIUC models:
fgfs --aircraft=747 --mach=0.7 --altitude=30000 fgfs --aircraft=dc3 --vc=130 --altitude=12000 fgfs --aircraft=j3cub --vc=60 --altitude=500 --offset-distance=1 The main difference is that YASim does not yet have a trimming routine, so you need to get right on the controls (things are not too bad if you choose a normal cruising speed and the controls start near neutral).
