Q

What should you do after placing the throttle to IDLE for a fire warning if the FIRE light goes out?

A

Check the bulbs. If one or both bulbs of the affected fire light does not illuminate, it indicates a possible burn-through of one or both fire sensors. In this case, shut the engine down.

Q

What should you check after shutting down an engine for a FIRE warning?

A

Verify engine shutdown by checking fuel flow and RPM. If the engine cannot be shutoff with the throttle, or if RPM/FF check bad, FUEL SHUTOFF (affected engine) shall be closed

Q

Checklist items for oil system malfunction if 5-55 PSI pressure cannot be maintained or if engine seizure appears imminent

A

Shut down that engine

20
Q

What are the indications of a sheared oil pump shaft?

A

Simultaneous failure of the engine RPM indications and oil pump (RPM and oil pressure indicate zero)

21
Q

Can you restart an engine that was shut down for oil system malfunction?

A

Yes. If the operating engine requires shutdown, the engine previously shut down for oil system malfunction may be restarted.

22
Q

If you restart an engine with a sheared oil pump shaft, at a minimum, what will be different about engine operations?

A

You will not get full operation due to the T5 system not receiving power from the tachometer generator

23
Q

If you are about to shut down the right engine, what should you do?

A

Check crossover

If it is not good, consider slowing down and lowering 60% flaps and trimming for final approach speed

If it is good, leave the gen switch off

24
Q

With a nozzle stuck closed, what might happen on landing roll? What should you do if this happens?

A

You might get an overtemperature on landing roll

If this happens, shut the engine down

25
Q

What is a consideration for approach and landing with either stuck nozzle condition?

A

Consider landing with single engine procedures.

26
Q

What should you do with a nozzle stuck closed (0%)? What should you do if EGT increases above acceptable limits?

A

Consider landing with single engine procedures.

Shut the engine down.

27
Q

WIth nozzle position fluctuating greater than +-3% in flight, crosscheck ___ to avoid misinterpreting a fluctuating nozzle as a _____ .

A

Fuel control problem

28
Q

General checklist flow for nozzle stuck closed

A
  1. Thottle - Retard to keep EGT within limits
  2. Land as soon as practical
29
Q

General checklist flow for nozzle stuck open

A
  1. Abort the mission
  2. Land as soon as practical
30
Q

General checklist flow for fluctuating nozzle

A
  1. Throttle - Retard until nozzle stabilizes
  2. Land as soon as practical
31
Q

Fluctuating nozzle could possible be attributed to ___ failure.

32
Q

_____ may be an indication of engine damage, even with normal engine indications displayed on EED.

A

Any abnormal engine noise

33
Q

It is possible for the oil pressure gauge to indicate 0 PSI at airspeeds up to ____ KCAS when the motor is windmilling.

34
Q

General checklist flow for engine failure / shutdown during flight

A
  1. Safe single engine airspeed - Attain
  2. Throttle gate - Disengage
  3. Throttle - OFF
  4. Crossfeed - As necesary
  5. Land as soon as possible
35
Q

General checklist flow for engine failure / shutdown during flight: with less than 250 lbs in either system

A
  1. Left and right boostpumps - ON
  2. Crossfeed - ON
  3. Land as soon as possibe
36
Q

General checklist flow for engine restart during flight

A
  1. Throttle gate - disengage
  2. Throttle - off (10s minimum)
  3. Below FL250
  4. Greater than 12% RPM (18-20 is the heart)
  5. Bat, Breakers, Boost Bumps - On
  6. Start button - press
  7. Throttle - Idle
37
Q

For an engine restart during flight leave the throttle in idle for ___ seconds before aborting a start

38
Q

General checklist flow for engine restart during flight if restart attempt fails

A
  1. Throttle (affected engine) - Off (for approximately 10s)
  2. Crossfeed switch - On
  3. Attempt another restart
39
Q

The RPM may hang up during restart after combustion occurs at low airspeeds. This may be eliminated by…

A

increasing airspeed

40
Q

If both engines fail during flight at low altitude and with sufficient airspeed, the aircraft should be zoomed (approximately ___ degree nose up attitude) to exchange airspeed for altitude

41
Q

Can you attempt multiple alternate airstarts or just one? If so, how?

A

Yes.

Wait 30 seconds for the ignition cycle to end. Retard the throttles out of the max range. Then slam them bad boys back to MAX AB

42
Q

Low altitude and high airspeed compressor stall indications

A

Pop, bang, or buzz; rapid RPM drop or high EGT

43
Q

High altitude and low airspeed compressor stall indications

A

Audible chug or pop, decreasing RPM and decreasing EGT

44
Q

General checklist flow for a compressor stall

A
  1. Throttle idle
  2. Start button - press
  3. Increase/decrease airspeed as necesary
  4. EGT/RPM monitor
45
Q

General checklist flow for a compressor stall if engine will not restart or recover

A
  1. Throttle gate - disengage
  2. Throttle - off
