Buznee Posted January 17, 2009 Posted January 17, 2009 Anyone having issues with the Standby Attitude Indicator losing calibration? I'm not sure exactly but I think it might be linked to when the schval screen reboots randomly in flight.
RvETito Posted January 17, 2009 Posted January 17, 2009 It's still under investigation. Sometimes it drifts, sometimes in the same conditions it works normal. Better wait some time after powering it from it's switch before uncage it. "See, to me that's a stupid instrument. It tells what your angle of attack is.

ZaltysZ Posted January 17, 2009 Posted January 17, 2009 It is sensitive to hard maneuvering. Some attitude indicators can only tolerate a specific range of bank angles. If the aircraft rolls too steeply, while performing aerobatics, the attitude indicator can "tumble" and become temporarily unusable. For this reason, some attitude indicators are fitted with a "cage" or "zero-ing" switch to reset it. In WWII this sensitivity to maneuvering tended to induce mistakes of some novice pilots: they tried to use ADI for orientation after they have entered cloud in the heat of dogfight and of course ADI showed nonsense.

When you 'reset' do you mean re-cage?

Buznee Posted January 18, 2009 Author Posted January 18, 2009 Yeah I just tried it, you hold right click on the knob next to the SAI and scroll until it locks. Then wait a little while until it centers, then scoll on it again until it uncages and then you can adjust for pitch.
