Q

What does WML mean on the engine indication?

A

Windmilling engine

The FADEC has detected a flameout and the auto relight system is actuating to restart the engine

24
Q

What does WML mean on the engine indication?

A

Windmilling engine

The FADEC has detected a flameout and the auto relight system is actuating to restart the engine

25
Q

What is ATTCS?

A

Automatic Takeoff Thrust Control System

26
Q

What does ATTCS provide?

A

Provides maximum thrust reserve (RSV) according to the current rate previously selected via the MCDU on the TO DATASET page

27
Q

What will trigger an ATTCS event?

A

N1 difference >15%
Engine failure during a go around
Engine failure during takeoff
Windshear

28
Q

What is ATTCS controlled by?

A

FADEC

29
Q

When is ATTCS available?

A

Takeoff and go around

30
Q

How can the pilot manually command RSV power?

A

By moving the thrust levers to MAX when the ATTCS is armed

31
Q

What do the ATTCS buttons on the EICAS represent?

A

ATTCS labeled in white- system is armed

ATTCS labeled in green- system is engaged

32
Q

When does the ATTCS system engage?

A

When the thrust levers reach the TOGA position

33
Q

When is thrust reverse available?

A

Weight on wheels

34
Q

When is the thrust reverser displayed on EICAS?

A

Whenever the thrust reverser is not stowed

35
Q

Thrust reverser must be stowed below what speed?

A

60 knots

36
Q

What does the green REV on EICAS mean?

A

Thrust reverser is fully deployed

37
Q

What does an amber REV on EICAS mean?

A

Reverser in transition

38
Q

What does a red REV indication on EICAS mean?

A

Discrepancy between selected and actual reverser position

39
Q

What happens if a thrust reverser inadvertently deploys in flight?

A

FADEC limits respective engine thrust to IDLE

40
Q

What position must the thrust levers be in to enable the thrust reverser trigger?

A

IDLE

41
Q

If the thrust lever is placed in the MAX REV position and then released, what does it do?

A

It is spring loaded back to the MIN REV position

42
Q

Can you deploy the thrust reverser on an engine that has failed on the landing roll?

A

Yes, up to 30 seconds following the failure, otherwise it is locked out

43
Q

What is a Flex Thrust Takeoff?

A

Reduced thrust takeoff based on assumed temperature

44
Q

What is the maximum flex allowed?

A

25% reduction

45
Q

If you input a flex of 34, then change it to 39, how will it affect your N1 target?

A

It will lower the N1 target

46
Q

Does the use of wet runway analysis numbers consider the increased stopping distance that occurs on wet runways?

A

Yes

47
Q

If the thrust levers are not set to TOGA detent by 60 knots, which EICAS message will display?

A

TLA NOT TOGA

48
Q

What is the memory item for ENGINE ABNORMAL START?

A

___ START/STOP………….STOP

49
Q

What is the memory item for ENGINE ABNORMAL START?

A

___ START/STOP………….STOP

2

52
Q

What do red EICAS Engine Limit Display Markings mean?

A

Maximum and minimum limitations

53
Q

What do amber EICAS Engine Limit Display Markings mean?

A

Caution range

54
Q

What do green EICAS Engine Limit Display Markings mean?

A

Normal operating range

55
Q

When are flex takeoffs prohibited?

A

Runway is contaminated with standing water, slush, snow or ice
Windshear is present or suspected
Or performance mandates NO FLEX

56
Q

When is single engine taxi not authorized?

A

Braking action less than good
