Instrument Failures
MOTIVATION
An aircraft's instrument systems are subjected to an exceptionally harsh environment of
g loading and extremes of temperature, pressure, and humidity. It is a tribute to the
efforts of manufactures and maintenance personnel that we so rarely experience an
instrument failure in flight. Although rare, instrument failures do happen, so it is crucial
that you be prepared to handle one safely.
If you have a good scan, losing an instrument should mean little more than adapting
your scan to substitute another instrument for the one that you have lost.
