Partial Panel

Instruments fail. I’ve had instruments with slight or major failures at least once a month in my flying career. It is not a big problem when you consider the redundancy of instruments that is available to the pilot.

Flying with failed or inoperative instruments requires you to learn partial panel flying techniques. This may require you, for example, to use the magnetic compass for turns in the event of gyroscopic failure. Or it may require the pilot to use a combination of attitude indicator to replace a failed vertical speed indicator or altimeter. No replacement is ever perfect, but it will help you to complete your flight safely.

During your instrument flight training, your instructor will cover selected instruments in the aircraft, or fail them in the simulator or flight training device. It is important that you learn how to scan selectively in the event of failures.
