Do not allow autopilot keyboard override

[ArcanePython931]

There were two topics about C172 autopilot, in either case, it was not clear what happened at first…

I never use autopilot… in the first topic, it turned out that AP was activated without my knowledge… and I met the issue, at first without knowing what was going on (or to get out !)

The second topic was posted by someone who does like to use AP, but ran into similar issues (instability).

Violent autopilot induced aerobatics. So frustrating [SOLVED]

Hi friends, I really enjoy this game - until I have to engage the [word not allowed] autopilot I fly only small GA planes like the C172 and Carbon Cub. The following happens in those planes: I create the GPS flight plan, verify all is correct. The magenta line appears from departure to destination I verify that GPS is selected as primary nav source I take off and fly manually onto the heading and until the planned altitude (usually 3,500 or 4,500ft). All is wel…

In both cases, it turned out that keys used for aeleron and elevator are active during autopilot. MS/Asobo could disable these keyboard couplings during AP, problem solved. For self helpers: check your keyboard couplings and avoid aeleron/elevator keys during autopilot !
