ORAL SAMPLE QUESTIONS Flashcards
How do you set the parking brakes on a “COLD” airplane? (What creates pressure for the power brakes)
Press tow pedals, pull parking brake handle with battery connected / batt-on DC motor-driven HYDRO pump pressurizes brake accumulator, mechanically by depressing toe brakes
What does each position of the BATT Switch do?
BATT: (BATT RELAY) CLOSES / (EMERG RELAY) DENERGIZED
OFF: (BATT RELAY) OPEN /
(EMERG RELAY) DENERGIZED
EMER: (BATT RELAY) OPEN / (EMERG RELAY) Hot Batt Bus
What does each position of the GEN switch do?
GEN: ALLOWS GCU TO CLOSE POWER RELAY (connects GEN to feed its BUS)
OFF: OPENS THE POWER RELAY (no load to feed bus)
RESET: CLOSES GEN FIELD RELAY IF OPENED and NO FAULTS EXISTS
Why does reducing power cause illuminated BLD AIR O’HEAT Annunciator to extinguish?
Reduced heat of Bleed Air From HI STAGE COMPRESSOR
Why would moving the throttles to idle cause an illuminated ENGINE FIRE light extinguish?
Reduces Bleed Air leaks (heat) sensed by fire loop
