Dear Dan,
I have a small problem regarding the christmas release of the DGIV. Whenever I enable the Hold Speed Autopilot (PRO 400 SPEC nn), I can't control the glider anymore. Pressing NumPad 4, 6, 8 or 2 gives an error ("Command disabled by safety during this autopilot"). Control with a joystick still works.
I don't think that this is intented, because it usually results in a crash landing (if you are not using a joystick).
Regards,
Georg
