Engines / APU Flashcards
What is required for selection of Reverse thrust?
The related forward thrust lever must be at IDLE.
What fuel valve(s) close when an engine Start Lever is moved to CUTOFF?
Spar Fuel Shutoff Valve and Engine Fuel Shutoff Valve close.
What component controls and monitors engine parameters?
EEC
The Electronic Engine Control (EEC) provides exceedance protection for which parameter(s) in normal mode?
N1 and N2 redline overspeed protection.
In Normal Mode, what does the Electronic Engine Control (EEC) use to calculate N1 thrust ratings?
Sensed flight conditions and bleed air demand.
What are the possible EEC modes with the Engine EEC switch showing both the ON (white) and ALTN (amber) displays illuminated?
Soft or Hard Alternate Control Mode.
Compare thrust in EEC HARD ALTERNATE Mode to normal mode for a given thrust lever position.
Thrust is the same or greater.
What does an ENGINE CONTROL (amber) light mean?
EEC detects faults in the Engine Control System that are not dispatchable.
What mode is active with the Thrust Mode Display indicating R-TO (green)?
Reduced Takeoff.
What causes the ENG FAIL Alert (amber) on the EGT indicator?
Respective engine is operating at a condition below sustainable idle (50% N2) and the Engine Start Lever is in the IDLE position.
What removes an ENG FAIL Alert (amber)?
Engine recovers, start lever is moved to cutoff, or the fire switch is pulled.
On the ground, after engine shutdown, what does a red box on the EGT Readout indicate?
In flight engine exceedance occurred.
What does “reverse video” displayed on the Engine Vibration readout indicate?
When vibrational scalar units exceed 4.0.
What should the ENG VALVE CLOSED lights (blue) and SPAR VALVE CLOSED lights (blue) indicate during a normal preflight, power ON, Engines not running?
Dim Blue.
What does an illuminated FILTER BYPASS light (amber) indicate?
Indicates an impending fuel filter bypass due to a contaminated filter.
What is the indication if the engine oil pressure drops below redline during takeoff roll (>80 kts)?
Low Oil Pressure steady amber annunciation.
What does the Ignition Select Switch in the IGN R position select?
Selects the right igniter on both engines.
In flight, what does the Engine Start Switch in CONT provide with the Engine Start Lever in IDLE?
Operation of the selected igniter continuously.
In flight, what does the Engine Start Switch in FLT provide with the Engine Start Lever in IDLE?
Operation of both igniters continuously.
What does a steady START VALVE OPEN (amber) light indicate?
Start valve is open so bleed air can be supplied to the starter.
What does an amber REV indicate?
Reverser sleeve in transit.
What does a green REV indicate?
Thrust sleeve in deployed position.
What does a REVERSER (amber) light on the Aft Overhead Panel indicate?
Illuminates when the reverser is being stowed or a malfunction occurred after 12 seconds.
Which APU lights will accompany an automatic APU shutdown.
LOW OIL PRESSURE, OVER SPEED, or FAULT light.
