Powerplant Flashcards
What model of engine do we use on our aircraft?
AE3007A1P. AOM 2-10-05 page 1.
How many pounds of thrust can the engine produce?
The A1P engine has a maximum takeoff thrust of 8,169 lbs, flat-rated to ISA+19 C. AOM 2-10-05 page 1
How many FADECs control each engine?
2 (1 at a time). AOM 2-10-40 page 1.
Which FADEC channel normally provides engine control?
The active FADEC is alternated at each engine ground start. AOM 2-10-40 page 2.
Where is the active FADEC channel indicated?
On the EICAS. AOM 2-10-60 page 6
How can you manually change FADEC channels?
By selecting ALTN with the FADEC Selector Knob on the overhead panel.
AOM 2-10-40 page 2.
Which accessories are located on the accessory gearbox?
- The Fuel Pump and Metering Unit (FPMU),
- Permanent Magnet Alternator (PMA),
- oil pump,
- hydraulic pump,
- generators (2),
- air turbine starter.
AOM 2-10-05 page 3.
What is the maximum oil quantity of the oil tank?
12 quarts. 2-10-15 page 1.
Where is an indication of oil level provided?
On the T/O page on the MFD.
AOM 2-10-60 page 10
What does the PMA provide power to?
The ignition system and FADEC.
AOM 2-10-25 page 1.
What provides power for the FADECs prior to the PMA doing so?
The DC system. AOM 2-10-25 page 1.
What is the sole source of power for the igniters?
The PMA. AOM 2-10-25 page 1.
How do you perform an engine dry motor?
Place the Ignition Selector Knob in the OFF position and select START on the engine START/STOP knobs. AOM 1-03-45 page 4.
While airborne, FADEC will attempt a flameout relight until the engine speed reduces to what speed?
53% N 2 . AOM 2-10-40 page 8.
During in-flight restarts, which ignition systems are used?
Both. AOM 2-10-40 page 8
If ALT T/O-1 mode is selected for takeoff and an engine failure occurs, which mode is triggered by the ATTCS?
T/O-1. AOM 2-10-50 page 3.
In flight, when is T/O thrust mode selected automatically?
In flight, below or descending through 15,000 ft, when the landing gear is down and locked. AOM 2-10-50 page 4.
Which takeoff thrust mode is triggered by advancing one or both TLAs above the THRUST SET position?
T/O RSV. AOM 2-10-50 page 5
During a ground start, when does the FADEC activate the ignition system?
Approximately 14% N 2 . AOM 2-10-50 page 16.
After any aborted start, an engine dry motor must be performed for at least how many seconds?
30 seconds. AOM 2-10-50 page 17.
How many locking systems do the thrust reversers have?
- AOM 2-10-70 page 1.
During normal operation with the thrust reversers in the stowed position, which lock(s) are active?
The primary only. If the primary lock fails, the secondary lock activates, followed by the tertiary lock if the secondary lock also fails. AOM 2-10-70 page 1.
In order for FADEC to command reverse thrust, what conditions must be met?
Airplane on the ground, indicated from both main landing gear and main gear wheel speed above 25 kts, or the airplane on the ground indicated from both main landing gear and the nose landing gear. AOM 2-10-70 page 2.
What are the memory items for engine fire, severe damage or separation?
Associated Thrust Lever…IDLE, Associated Start/Stop Selector…STOP, Associated Fire Extinguishing Handle…PULL (DO NOT ROTATE). AOM 1-03-11 page 1.
What are memory items for an Abnormal Engine Start?
To abort start: Associated Thrust Lever…IDLE, Start/Stop Selector…STOP. AOM 1-03-45 page 3.
