A
20-60 PSI
24
Q
If no Oil Pressure is observed within __ seconds of engine start, call “Stop Start” and terminate start.
A
30 seconds
25
When the start selector is released at 35%, with No rise in Duct Pressure and Valve Open indicator is illuminated call ___ and complete what steps?
Call "No Cutout", and set throttles to CUTOFF, Close Wing Isolation Valves, and Shut off starter Air Source
26
___ occurs when EGT does not increase within 20 seconds after the throttle is moved to Idle.
Wet Start:
- Below 35% N2: set throttle to cutoff, hold starter switch to GND Start for 15 seconds to clear unburned fuel
27
Sustained Fuel Flow at light off above 1400 PPH indicates ___?
Impending Hot Start
- Below 35% N2: set throttle to cutoff, hold starter switch to GND Start for 15 seconds to clear unburned fuel
- Above 35%: Throttles to cutoff, allow the engine to stop rotating and determine the cause before attempt another start
28
EGT rapidly increasing or above 405 degrees C, indicates ___?
Impending Hot Start
- Below 35% N2: set throttle to cutoff, hold starter switch to GND Start for 15 seconds to clear unburned fuel
- Above 35%: Throttles to cutoff, allow the engine to stop rotating and determine the cause before attempting another start
29
N1/N2 not increasing or increasing slowly, while EGT is rapidly increasing, indicates ___
Hung Start
- Set throttles to cutoff and hold start selector switch to GND Start for 15 seconds to clear fuel.
- Do Not attempt to restart until N2 RPM decreases to ZERO and cause has been determined
30
N2 RPM below 54% two minutes after fuel on
Throttles Advanced
- Throttles to cutoff
31
If start selector switch is released from GND Start below 35% N2
Set throttle to Cutoff, allow engine to stop rotation, motor for 15 seconds
32
If ____ has tripped, do not reset until throttle is in Cutoff and start selector switch is in OFF position.
Start Control and Ignition CB (tailpipe fire or torching can result if CB is not reset first
33
No drop in duct pressure or Valve Open indicator failed to illuminate when start selector switch set to GND Start
Failure to Start
34
N2 and Oil Pressure do not increase
Failure to Start: Release the start switch immediately to prevent additional damage to starter due to sheared starter shaft
35
If the ground crew reports tailpipe fire
Proceed as Wet/Hot Start and motor engine for 15 seconds
36
Fuel Enrichment may be used when below __ degrees F and must be used when below __ degrees F.
maybe used: below 32F
will be used: below 0F
37
Nacelle Anti-Ice will be used when ___
OAT is 10C or below and visible moisture present
38
If Nose Cowl Anti-Icing Valve does not open within 1 second at Idle thrust, increase thrust to ____ N1
37-40%
DO NOT EXCEED 40%
-Failure to open within 1 sec indicates valve sticking due to corrosion
-Failure to open at 1.2 EPR, the valve failed
39
If Low RPM light fails to go out during engine start, make how many attempts to close the generator breaker?
One attempt
40
If Generator Breaker does not close, what actions do you take?
Shutdown that engine and have maintenance visually check the integrity of the IDG to verify if the IDG was disconnected
41
If Low RPM light stays illuminated after restart, ___ and resume operation with generator ___.
disconnect IDG / inop
42
If Generator Breaker closes, line comes on, and Low RPM light remains illuminated, the cause is ___.
Faulty speed sensing circuit
43
If APU shuts down during power transfer or for no apparent cause have condition of ______ checked prior to any restart attempt
APU accessory drive shaft checked
44
if any generator outside of limits (400 +/-8 Hz) with normal indications (No Low RPM light/Oil temp norm) what actions are required?
Shutdown Generator, ensure Fuel Flow is normal then disconnect IDG. Do Not Disconnect with abnormal FF
45
LOW caution light illuminates when total fuel on board is below
9000 lbs
46
Close tank refuel valves ____ below desired level to allow for valve closing
300 lbs
