T-45C TS, ADV & IUT ENG-20
Flight Instruments Malfunctions
a. During taxi: turn needle does not deflect in direction of turn,
or slip indicator fails to move opposite turn
b. Airborne: turn needle does not deflect with turn, or slip indicator
does not respond to rudder movement
c.
Power failure flag appears
2. Verifications
a. Perform a timed standard rate turn to see if you get proper turn
needle deflection
b. Apply rudder pressure to confirm slip indicator failure
3. Effects on flight safety: Standby turn and slip indicator is an
essential instrument during out-of-control flight recovery
C. Standby attitude indicator (Standby AI) failure
1. Indications
a. Indicator frozen, not erect, or unreliable
b. Red/orange flag appears
c.
OFF flag may appear
2. Verifications
a. Cross-check ADI display
b. Cross-check Standby AI or ADI indications in other cockpit
c.
Cross-check outside references
3. Effect on flight safety: loss of attitude reference backup
D. Standby compass failure
1. Indication/verification/effects on flight safety: The standby wet
compass rarely fails unless physically damaged
E. Clock/stopwatch failure
1. Indication/verification/effects on flight safety: The clock/stopwatch
rarely fails unless physically damaged. If the clock/stopwatch fails,
back-up is GPS time readout on the HUD or MFD GPS page
