Engines And APU Flashcards
The EEC when operating in the Alternate mode: [8.70.10]
- Provides no Thrust Limit (overboost) protection.
- Provides N1 and N2 overspeed protection.
In flight, the EEC selects approach idle if: [8.70.10]
- Flaps are 25 or greater.
- Landing gear is selected down.
The autostart system monitors
- Oil pressure
- Hot or hung starts
A low oil quantity condition will be annunciated on EICAS by: [8.70.10]
Reverse highlighting (black numbers on a white background) the oil quantity display.
The reverse thrust levers can be raised only when: [8.70.10]
On the ground with the forward thrust levers in the idle position.
The APU is operating in the attended mode when: [8.70.30]
- Either engine is starting or running.
- The airplane is in flight.
The engine autostart system will make a maximum of three start attempts before
aborting the engine start sequence when in flight. [8.70.10]
True or False?
False.
When the thrust levers are positioned to the full forward position, the ___ provides
N1 and N2 overspeed protection. [8.70.10]
EEC
On the ground, the engine autostart system will not attempt a second start after which of the following malfunctions? [8.70.10]
Loss of both starter/generators.
Manual engine starts are accomplished: [8.70.10]
Manual starts are not available.
Regardless of the EEC switch position, thrust is set using: [8.70.10]
N1 as the controlling parameter.
While operating in the UNATTENDED mode, the APU will shut down for: [8.70.30]
A. An overspeed.
B. High EGT.
C. Speed droop.
D. All the above.
With the FUEL CONTROL switch in the CUTOFF position, the associated fire switch: [8.70.20]
Is automatically unlocked.
The GEnX 1B76 engines on the 787-9 are rated at: [8.70.10]
76,100 pounds T/O thrust.
If an engine indication reaches a redline value, the indicator digital readout, pointer, dial change to a red color. The indicator color change can be reset to white (if the exceeded parameter has returned to normal) by: [8.70.10]
Pushing the Cancel / Recall switch.
If AUTORELIGHT is displayed above N2: [8.70.10]
- Both igniters are running in the continuous condition.
- The fuel control switch is in RUN and engine speed has decayed to below idle.
The thrust ramping feature compensates for high stress loads due to crosswinds or low groundspeeds. What effect does this have on engine operation? [8.70.10]
Maximum T/O thrust may not be reached until 65 KIAS.
Which statement is correct regarding APU operation? [8.70.30]
Electrical power is available when at or below 43,100 ft.
When the reverse thrust levers are moved aft to the interlock position, the autothrottles disengage and the auto speed brakes, if armed, deploy. [8.70.10]
True or False?
True.
Regarding the Engine Oil System: [8.70.10]
A. There is no minimum oil quantity limit for operating the engine in flight.
B. Oil is pressurized by an engine-driven oil pump.
C. Minimum oil quantity prior to start is 18 quarts.
D. All the above.
When the APU LIMIT EICAS message is displayed: [8.70.50]
An APU limit has been exceeded.
With the EECs operating in the normal mode, what action will provide maximum available thrust? [8.70.10]
Manually positioning the thrust levers to the full forward position.
Which statement is TRUE concerning the hard alternate EEC mode? [8.70.10]
In the hard alternate mode, the EEC uses N1 as the controlling parameter.
Thrust control malfunction accommodation (TCMA) can automatically shut down an engine to protect against idle thrust asymmetry conditions while on the ground. [8.70.10]
True or False?
True.
