2) Abnormally slow acceleration
3) RPM stabilizes below ground idle

34
Q

What characterizes a FALSE START?

A

EGT rises with no RPM rise

35
Q

What characterizes a HOT START?

A

1) EGT exceeds 725 C

2) Fuel flow >680 PPH

36
Q

What characterizes a NO START?

A

EGT does not rise

37
Q

What characterizes a SUB IDLE START STALL?

A

1) N2 rolls back
2) EGT rises,
3) Fuel flow is NOT an indicator

38
Q

What should you do if the starter light fails to go out within 10 seconds and N2 is above 45%?

A

Place Throttles to CUTOUT and Bleed Air Valve to CLOSE

39
Q

What should you do if you have an IDG failure light?

A

Shut Down affected engine

40
Q

What happens if you shut the hydraulic pressure and auxillary pumps off prior to N2 reaching 0%?

A

The hydraulic reservoirs will overflow

41
Q

What happens if you shut off the fuel boost pumps prior to N2 reaching 0%?

A

the N2 core will cavitate

42
Q

Engine Danger areas at Idle thrust?

A

25 feet forward of engine inlet
5 feet to either side of engine inlet
180 feet aft of engine exhaust

43
Q

Engine Danger areas at TRT thrust?

A

50 feet forward of engine inlet
6 feet on either side of engine inlet
900 feet of engine exhaust

44
Q

Firefighting chemicals should not be directed into the engine air inlet or tailpipe unless

A

fire is restricted to those areas and is of serious proporitions

45
Q

What should you do before pulling the fire switch and why?

A

Always place throttles to CUT-OFF. Pulling fire switch first could damage the engine fuel pump

46
Q

Outboard engine run above idle, the corresponding engine on the opposite wing at a thrust setting

A

that approximates within 5% N1 rpm

47
Q

When running an inboard engine above 40% N1 rpm, maintain balanced thrust by operating the corresponding engine on the opposite wing at a thrust setting

A

that approximates within 5% N1 rpm

48
Q

During icing conditions, prior to exceeding 70% N1 if engine has operated at idle for more than 10 minutes, accelerate engine to

A

35% N1 to shed initial ice and check for unusual vibration or noise then accelerate slowly to 70%N1 and hold for 15 seconds to shed remainder of ice

49
Q

Do not re-engage pneumatic starter above what?

A

25% N2. Re-engagement above this speed may result in starter damage

50
Q

A stall is indicate by

A

abornmal engine noises, loud reports accompanied by flame from the engine exhaust and possible from engine inlet, fluctuating performance parameters, sluggish or no throttle response.

51
Q

How long can you use the ignition system?

A

designed for unlimited use.

52

10 seconds (normal combustion 2-3 seconds)

53
Q

Pneumatic starter initiates automatic cutout between ___ and ___ N2 and takes ___ to ___ seconds to complete cutout sequence

A

43% and 45%

3 to 9 seconds

54
Q

How much oil pressure before placing throttle lever to IDLE

A

11 psi

58
Q

Max EGT for continuous power and below is

A

870 C

59
Q

Why do you place the GEN BREAKER switches to CLOSE and then TRIP?

A

To prevent the generators from automatically coming on line after engine start

60
