26
>ENG CONTROLS
3-4 EEC systems opérate in degraded mode. Systems don’t have full redundancy.
27
ENG IGNITION
CONT IGN SYS Has failed
28
ENG 1,2,3,4 FAIL
An eng fail Or Flameout
29
ENG 1,2,3,4 Control
EEC sys fault occurs

>AUTOSTART OFF
N919CA AND N952CA onlyEngine Autostart switch is off
31
APU FUEL
Low pump pressure is detected when activated OrAPU fuel valve NIPS
32
What does a magenta oil quantity mean?
Low oil
33
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?
There is none, however a magenta vibration notes the high vibBB- broadband (vibration over whole engine)
34
ENG 1,2,3,4 OIL PRESS
Low oil press Engine damage or failure possible
35
ENG 1,2,3,4 OIL TEMP
High oil tempPossible engine damage may occur
36
ENG 1,2,3,4 FUEL VLV
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
What does the light mean in the start switch?
Start valve open
38
When does the start valve open on start?
When fuel control switch is in run.
39
What does the red limit line on EGT signify during start?
Max start temp
40
What 3 things does Autostart not monitor?
N1Oil temp Oil pressAbort or shutdown if no N1 or oil press by Idle N2
41
What does Autostart do if it does not detect EGT rise?
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
If the Autostart detects an EGT rise but detects a hot or hung start what does it do?
it cuts fuel, adjust fuel schedule and reapplies for another attempt.
43
In a manual start when to add fuel?
When it reaches the fuel on indicator on n2
44
When will autostart terminaré start attempts for an inflight start?
When the engine starts or the pilots selects fuel cutoff
45
If the auto igniter is in single what does it do each flight?
Alternates between 1&2 every other flight
46
When does auto ignition activate?
Start with less than 50% N2Flaps out of upNAC ONFLAMEOUT (both)
47
What does selecting stby ignition to 1 or 2 do?
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
STARTER CUTOUT 1,2,3,4
Start valve does not close (at 50% N2 after start finished)(Light in start switch doesn’t go out)
49
ENG 1,2,3,4 AUTOSTART
Autostart ON, engine failed to start.Fault detected in Autostart systemStart parameters exceededManual start EGT parameters rapidly reaching limitManual start RUN selected too early.
50
What does raising the reverse thrust levers to idle do?
Disc auto throttle Raises auto speed brakes if not armed before landing (Does the same on a rejected takeoff)
51
>ENG 1, 2,3,4 REVERSER
Fault detected in the reverser system
52
ENG 1,2,3,4 FUEL FILT
Fuel contamination can cause fuel to bypass the engine fuel filter
53
ENG 1,2,3,4 LOW IDLE
ENGINE IDLE not in approach setting when commandedAdvance thrust til extinguished
54
ENG 1,2,3,4 OIL FILT
Oil Filter contamination can cause oil to bypass the oil filter
55

40%N22 min
58
What is the cool down time fir the Pratt’s and GE’s after landing?
Pratt’s 5 minGE 3 min
