A

N919CA AND N952CA onlyEngine Autostart switch is off

31
Q

APU FUEL

A

Low pump pressure is detected when activated OrAPU fuel valve NIPS

32
Q

What does a magenta oil quantity mean?

A

Low oil

33
Q

What is the certified vibration limit?If the vibration monitoring system cannot detect if N1 or N2 are the culprits what does the indicating system show?

A

There is none, however a magenta vibration notes the high vibBB- broadband (vibration over whole engine)

34
Q

ENG 1,2,3,4 OIL PRESS

A

Low oil press Engine damage or failure possible

35

A

One or more of these:Engine fuel valve NIPSSpar valve NIPSIf during start, engine won’t start.In shutdown, engine continues to run until remaining fuel is burned.

37
Q

What does the light mean in the start switch?

A

Start valve open

38
Q

When does the start valve open on start?

A

When fuel control switch is in run.

39
Q

What does the red limit line on EGT signify during start?

A

Max start temp

40
Q

What 3 things does Autostart not monitor?

A

N1Oil temp Oil pressAbort or shutdown if no N1 or oil press by Idle N2

41
Q

What does Autostart do if it does not detect EGT rise?

A

Cuts fuel and ignition, motors for 30 secs.Then applied ignition to both igniters and fuel . Three attempts before aborting Autostart Motors for 30 secs before start and bleed air valves close.

42
Q

If the Autostart detects an EGT rise but detects a hot or hung start what does it do?

A

it cuts fuel, adjust fuel schedule and reapplies for another attempt.

43
Q

In a manual start when to add fuel?

A

When it reaches the fuel on indicator on n2

44
Q

When will autostart terminaré start attempts for an inflight start?

A

When the engine starts or the pilots selects fuel cutoff

45
Q

If the auto igniter is in single what does it do each flight?

A

Alternates between 1&2 every other flight

46
Q

When does auto ignition activate?

A

Start with less than 50% N2Flaps out of upNAC ONFLAMEOUT (both)

47
Q

What does selecting stby ignition to 1 or 2 do?

A

Applies stby power as the power to that igniter continuouslyIn norm, it is powered by AC pwr. However if the AC power is not powered igniter 1 is powered by stby power continuously.

48
Q

STARTER CUTOUT 1,2,3,4

A

Start valve does not close (at 50% N2 after start finished)(Light in start switch doesn’t go out)

50
Q

What does raising the reverse thrust levers to idle do?

A

Disc auto throttle Raises auto speed brakes if not armed before landing (Does the same on a rejected takeoff)

> ENG 1, 2,3,4 REVERSER

A

Fault detected in the reverser system

52
