pressure to provide airspeed, altitude, and rate of
climb information for the system. Standby flight
instruments receiving pitot static input are the
standby altimeter, standby airspeed indicator, and
the standby VSI

Independent instruments: the independent flight
instrument systems include the radar altimeter, the
standby AI, the standby compass, and the clock/
stopwatch
NOTE: 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.
