Type Rating 2 - Power Plant, Comms, HYD 1 Flashcards
Which engines supplys power to the aircraft and how many FADECs installed per engine?
Both engines and the APU. 1 FADEC per engine, with 2 channels.
One channel is active and one is standby. If one fails, the other automatically takes control. They are channel A and channel B
When the engine is running, what causes the igniters to operate automatically?
EIU failure
Flame out
Ignition delay during start
What does FADEC do following an automatic start abort (hot, hung, stall, no light off)?
Gives an ECAM fault message, and runs an abort sequence if on the ground. This sequence is: Close HP valve Close start valve Turn off ignition Crank engine (clears fuel vapours) Controls any additional start attempts
During a normal (auto) start, what happens at 16%, 22% and 50% N2?
16% - Ignition starts
22% - HP fuel valve opens
50% - Ignition stops
Which is the only malfunction which will cause an auto-abort of an engine MAN Start?
On ground if EGT limit exceeded before reaching 50% N2, in which case FADEC aborts the start
Man start: When should the master be selected on?
When N2 reaches 22% or the maximum motoring speed (20% minumum)
Man start: What happens when the master switch is selected on?
Opens HP shutoff valve and operates both ignitors
Man start: what closes the start valve, and when?
FADEC closes the start valve and cuts off the ignition when N2 reaches 50%
What causes the fault light to illuminate on the engine panel?
Position of HP fuel shutoff valve abnormal, or automatic start sequence of the associated engine aborts, or malfunction of the thrust control, or start valve fault
What do MAN START pushbuttons control?
Controls the start valve
What is at one end of the transient N1 and what is at the other?
Commanded N1 and current N1 when A/THR active
On the EGT, what does the amber index indicate?
Max EGT. 725c during engine start and 915c in other cases
What does REV in amber/green indicate?
REV GREEN - on ground thrust reverser is fully deployed
REV AMBER - Thrust reverser system is unlocked
How can you tell that the start sequence has finished?
Grey shade around N2 disappears and then ECAM ENG SD page disappears
When does IDLE flash (between the N1 gauges)?
When both engines are at idle when in flight. Pulses for 10 seconds then remains steady
