Q

The blue command arc that appears on the EPR indicator provides a quick indication of the difference between:

A

The current EPR pointer and the EPR command value.

24
Q

The Command Arc that appears momentarily on the EPR indicator only appears during:

A

ATHR operation.

25
Q

A

EPR max limit.

26
Q

An amber REV appears on the EPR indicator when a reverser door is:

A

Not stowed or is unlocked.

27
Q

A flashing amber REV for 9 seconds which then displays steady, occurs when:

A

A reverser door unlocks in flight.

28
Q

The word AVAIL will display in green for 9 seconds on the EPR gauge after a successful:

A

Engine start on the ground. After a successful inflight relight AVAIL will flash for 9 seconds.

Red arc

31
Q

If the Maximum Permissible EGT is exceeded the display:

A

Turns red and the needle pulses red.

32
Q

If the EGT ever exceeds the Maximum Permissible value, a red radial mark appears at the:

A

Highest temperature point. This display remains in view until maintenance action or a subsequent takeoff.

33
Q

The maximum permissible N1 is:

A

100%

34
Q

Q

The maximum permissible N2 is:

A

36
Q

When the aircraft is in flight the thrust limit mode corresponds to the:

A

Detent of the most advanced thrust lever position.

37
Q

For the inflight thrust limit mode determination if a thrust lever is set between two positions the FADEC selects the rating limit corresponding to the:

A

Highest mode.

38
Q

IDLE appears on the EWD when:

A

Both engines are at idle.

39
Q

The last 2 digits of the fuel used display dashes to alert the crew:

A

Of an inaccuracy of the fuel used display (fuel flow data is interrupted for more than one minute).

40
Q

After engine start if the nacelle temperature is excessive —- will display at the bottom of the secondary engine instruments.

A

NAC

41
Q

The ignition is normally controlled by FADEC channel:

A

A, with B operating as a standby.

42
Q

The FADEC ————— igniters for each start attempt.

A

Alternates.

43
Q

When the associated Master switch is moved to ON during Manual starts:

A

Both igniters start to fire.

44
Q

Manual selection of continuous ignition is accomplished by:

A

Selecting IGN/START on the ENG START selector.

Q

If continuous ignition is desired after engine start, the pilot must first:

A

2 igniters.

49
Q

The yellow hydraulic system provides operating power to REV ENG:

A

2

50
Q

The low pressure fuel shut off valve is normally opened or closed by movement of the associated Master switch, however it is commanded closed if the:

A

Fire PB is released.

51
Q

The fuel used resets to zero by selecting the:

A

Master switch to ON.

53
Q

The EGT should increase within — seconds after the introduction of fuel.

A

20.

54
Q

Engine 2 is usually started first because

A

It powers the yellow hydraulic system that pressurises the parking brake

55
Q

In case the electrical power supply is interrupted during the start sequence (indicated by the loss of ECAM DU’s)

A

Abort the start by setting to off the engine master 2 lever then perform a 30 second dry crank.

56

During engine start do not select engine 2 master on before:

A
