Engines Flashcards
For takeoff, pilots will smoothly advance the Power Levers to the _____ position.
Rating Detent
T/F: The aircraft has auto-throttle capabilities.
FALSE, there are no auto-throttle capabilities
What is the shaft horsepower of each engine under normal takeoff conditions?
4580 SHP
What does the shaft horsepower increase to on the operating engine in the event of an engine failure after takeoff?

T/F: Propeller rotation is accomplished by turning of power turbines.
TRUE, but the power turbines are connected to a propeller reduction gearbox and the gearbox transmits the power to the propeller
Where is the accessory gearbox mounted on the engine?
Located at the top center of the engine and is driven by the high pressure compressor (NH)
T/F: The low pressure (axial) compressors are driven by their associated low pressure turbine.
TRUE
Which of the following represents the speed of the low pressure axial compressor?
NL
Which of the following represents the speed of the high pressure centrifugal compressor?
NH
What powers the power turbines?
Exhaust gas energy
When on the ground and the propellers are in the ground range of beta, it is indicated by:
Illumination of PROPELLER GROUND RANGE light on the far left side of the Captain’s glareshield
T/F: The propeller has a beta range used for reverse thrust on the ground.
TRUE
What is the purpose of the engine intake bypass doors?
Prevents solid contaminates from entering the engine
When should the engine intake bypass doors be selected open?
Icing conditions
Operation on contaminated runways
When should the engine intake bypass doors be open on the ground?
On contaminated runways
T/F: The auxiliary fuel pump is powered by the accessory gearbox.
FALSE, it is not powered by the accessory gearbox
T/F: The engine driven fuel pump is attached to the accessory gearbox.
TRUE
T/F: The oil pump is attached to the accessory gearbox.
TRUE
T/F: The DC starter generator is attached to the accessory gearbox.
TRUE
T/F: The permanent magnet alternator is attached to the accessory gearbox.
TRUE
T/F: The FADEC is the primary computer for engine control.
TRUE
What powers the FADEC once the engine is running?
An independent permanent magnet alternator (PMA)
What provides an alternate power source for the FADEC during engine starting or if a PMA failure occurs?
Essential buss provides alternate power
When the condition levers are set to the 1020 RPM detent, what do they command the FADEC to set power to?
Normal Takeoff Power (NTOP)
Or
Maximum Takeoff Power (MTOP) if the MTOP switch light
When the condition levers are set to the 900 RPM detent, what do they command the FADEC to set power to?
Maximum Climb Power (MCL)

Maximum Cruise Power (MCR)
What prop speed is automatically set when in the over-travel range?
1020 RPM
What must pilots do to enter the ground beta range?
Raise gate release triggers to move aft of FLIGHT IDLE and into BETA range
T/F: When in the MAX REV, propeller RPM is limited.
TRUE (950 RPM)
T/F: In order for uptrim to be armed, the power levers must be high and torque on both engines must be at least 50%.
TRUE
When is uptrim triggered?
Torque falls below 25% on failed engine
OR
Power turbine speed (Np) falls below 80%
