In aerobatic planes, it's possible to cage the gyros during maneuvers
to avoid this problem -- that's something we'll want to support
eventually.

Under /instrumentation/attitude-indicator, there is a property call caged.  
Would that be what you are referring to?

Yeah -- we need to link that to something the user can get at (but
again, only for aerobatic planes).

[Flightgear-devel] Properties under /orientations seem to have taken on offsets after extreme attitude

2005-01-10 Thread Ampere K. Hardraade
I was taking the c182 out for some tests last day, and I brought the c182 into 
some extreme attitudes.  Afterward, I notice that the attitude indicator 
seems to have jammed; tilted when the aircraft is in level flight.  Upon 
further testing, I noticed the roll rate of the indicator still corresponds 
to the roll rate of the aircraft.  The similar problem also occurs on the 
c172.  After some investigation, I traced the problem to properties 
under /orientations.

The issue can be reproduced by sending the aircraft into barrel rolls and 
other extreme maneuvers.

This is actually a real feature.  Your extreme manuevers have 
discombobulated your attitude indicator and it takes several minutes for 
the gyro to realign itself with gravity.
