Instrument Failures and Unusual Attitudes - Instrument Failure

Terms in this set (12)

Do entire systems or individual instruments fail mal more often?
Entire systems
What is one way to figure out which system/instrument is indicating erroneously?
Make a small pitch change and see which responds correctly
Control inputs when flying partial panel
It is very important to apply gentle, precise control input. Then, hold any new attitude and allow time to see the results. In other words, reduce the rate and extent of control movements as compared to operating on a full panel.
What is your biggest challenge in flying partial panel?
Bank control due to the loss of the heading indicator (for example, you still have your primary pitch instrument, the altimeter)
Primary and supporting heading instrument in level flight
Turn coordinator and compass, respectively
Pitch instrument during partial panel climbs and descents
VSI (don't forget the lag)
Partial panel tirns
Timed turns (note the degrees you want to turn, divide by 3, turn that long at standard rate, and then check on the compass afterwards)
What might cause an unusual attitude?
Being extremely busy and distracted, errors in instrument interpretation, lack of proficiency in aircraft control, turbulence, wake turbulence, a Gyro failure that catches you by surprise, vertigo, and/or simple confusion
If you notice any unusual instrument indication or rate of change not expected in normal Instrument Flying, or excessive she forces or unusual air noise...
Increase your scan rate to determine the actual attitude of the aircraft or if there is an instrument failure
On unusual attitude recovery, if the AI gives confusing indications compared to the other instruments...
Ignore it
If the attitude indicator tumbles during unusual attitude recovery...
You'll have to rely on the turn coordinator to level the wings (the DG can also help). You'll rely on the ASI and altimeter to level off.
What are three good habits to help avoid unusual attitudes?
- keep your scan moving (no fixation or slow cross-check)
- keep the airplane in trim so if you let go of the controls to do something else everything doesn't go out of wack
- keep the cockpit organized
