Engines

Question 1

What does the START/STOP selector knob in the STOP position do?

Answer 1

Commands the FADEC to shut down the engine

Question 2

What does the WML icon indicate

Answer 2

Windmilling indication

Question 3

What does the OFF position on the IGNITION SELECTOR KNOB accomplish

Answer 3

Deactivates the ignition. Fuel flow is inhibited on the ground. FADEC disregards the OFF position in flight.

Question 4

What does AUTO position on the IGNITION SELECTOR KNOB accomplish?

Answer 4

FADEC continuously activates both igniters while the engine is running

Question 5

On the IGNITION SELECTOR KNOB, if placed in the OFF position in the air, what happens to the igniters?

Answer 5

They continue to work as FADEC disregards this switch position in the air

Question 6

On the IGNITION SELECTOR KNOB, if placed in the OFF position on the ground, what system logic is there?

Answer 6

On the ground, fuel flow is inhibited

Question 7

When is the N1 wing anti-ice cyan line displayed?

Answer 7

Only in icing conditions below 1200 AGL with the landing gear down or flaps extended.

Question 8

What type of start malfunctions are there?

Answer 8

Hot Start
Hung Start
No Light Off
START VLV OPEN
No Oil Pressure

Question 9

Describe the flow of fuel

Answer 9

Fuel leaves the fuel tanks and flows through the low pressure fuel pump and then divides into two paths. One flows through the high pressure fuel pump and returns to the tank as motive flow. The second flows through the fuel / oil heat exchanger to the fuel filter, the FMU, then through the high pressure fuel pump before returning to the FMU.

Question 10

How is the SCV - Starter Control Valve opened?

Answer 10

By the FADEC. The FADEC opens and closes the SCV

Question 11

How many igniters are energized during engine starts?

Answer 11

One for engine starts on the ground

Both for inflight engine starts

Question 12

What does the OVRD position of the IGNITION knob accomplish?

Answer 12

Both igniters on each engine are energized

Question 13

When should the start be manually aborted?

Answer 13

When there is no light off within 30 seconds

No Oil Pressure

Question 14

Is there start protection logic for inflight engine starts?

Answer 14

NO
There is no protection during inflight engine starts for 
Hot Starts
Hung Starts
Failure to light off

Question 15

The ATTCS automatically commands Reserve Thrust when?

Answer 15

When it is engaged
Thrust Levers are in TOGA and one of the following:
N1 split of 15%
Engine failure on takeoff
engine failure during go around
Wind shear detection

Question 16

When does the FADEC automatically command an engine shut down?

Answer 16

When N2 reaches 102%

Question 17

Will the FADEC attempt to relight an engine automatically in the event of an overspeed?

Answer 17

In the event of 3 consecutive overspeed detection events within 30 seconds, the FADEC will not relight the engine

Question 18

On a hot start, the FADEC shuts off the engine how?

Answer 18

Simply by shutting off fuel to the engine. The SCV - Starter Control Valve is not automatically shut, hence the reason for the memory item and QRH
