Summary:
The independent flight instrument systems include the
radar altimeter, the standby AI, the standby compass,
and the clock/stopwatch.
The standby AI and standby compass are used primarily
as backups in the event that the main flight instruments/
systems (ADI, HSI, HUD displays) have failed.
The radar altimeter is used primarily during low-level
flight and landing operations. The clock/stopwatch is
used as a timepiece and to identify elapsed mission time.
