36
Q

FADEC controls ignition and starting system according to position of

ENG START SEL, ENG MASTER sw, ENG MAN START pb, ENG ANTI ICE pb

37
Q

All functions except _____________ remain available if the signal from EIU is lost

A

manual start and wet crank

38
Q

A start valve and ____________comprise the Engine Starting System

A

an air turbine starter

39
Q

In case of N1 rotor locked, how many more automatic start attempts after cracking does FADEC initiate?

A

0

40
Q

In terms of N3, the start valve closure valve is above

A

50%

41
Q

With ENG START SEL in CRANK position and MAN START pb selected ON,

A

Start valve opens

42
Q

With ENG START SEL set to NORM and ENG ANTI ICE ON,

A

Continuous ignition via FADEC channels A and B is also automatically selected

43
Q

With ENG START SELE set to NORM, in the event of an engine flame-out detected by FADEC

A

Continuous ignition is automatically activated for 10 seconds

44
Q

With ENG START SEL in IGN START position,

A

During an automatic start, ignition occurs on ground when N3 is at least 25%

45
Q

With ENG MASTER sw OFF, a signal is sent to

A

HP an LP fuel valves to close, which resets both FADEC channels

46
Q

With ENG FADEC GND PWR pb is selected ON, FADEC receives power from the aircraft network for five minutes except if the

A

ENG FIRE pb is out or the FADEC generator is available.

47
Q

The upper ECAM screen displays the primary parameters and the lower ECAM screen displays the secondary parameters when selected

A

manually or automatically

48
Q

The engine Primary parameters can be displayed on each Navigation Display using the selector on the EFIS Control Panel if

A

a Display Management Computer ECAM channel failure occurs.

49
Q

EPR commanded by FADEC is displayed via a green needle and a green triangle next to the needle indicates the direction of EPR tendency. The symbols are shown when

A

the Autothrust is active.

50
Q

Transient EPR is the difference between Actual EPR and EPR command. It is shown only when

A

the autothrust is active

51
Q

EPR MAX is a line displayed in

A

solid amber

52
Q

When the reverse thrust blocker doors are fully deployed and reverse thrust mode is selected,

A

the thrust reverse indication changes to green and is over-illuminated.

53
Q

When at or above idle, to indicate a successful engine relight in flight the

A

AVAIL indication pulses in green

54
Q

EGT indication becomes solid red if the EGT exceeds

55
Q

EGT MAX is not available when Takeoff Thrust is applied,

A

Red and a red cross appears beside it, which disappears after a new start on the ground

58
Q

A

4 quarts, numbers pulse.

59
Q

If vibration of N1 is greater than 3.3 units, N2 more than 2.6 units, or N3 in excess of 4 units,

A

the indication pulses

60
Q

FADEC detects

A

Hot, hung, no light up, surge, locked N1 rotor, FAULT ECAM starts

61
Q

After second engine started, ECAM ENGINE page is replaced by WHEEL page

A

15 seconds after start, if ENG START sw is not returned to NORM

62
Q

Rotating ENG START SEL to the ignition (IGN) position causes the pack valves to

A

Close and the ECAM ENGINE page to appear

63
Q

If after START sel is moved to the ignition IGN position the ENG MASTER sw is not moved to ON within

A

30 seconds, the pack valves reopen

64
Q

If START sel is not rotated back to NORM, the ECAM WHEEL page automatically

A

Replaces the ENG page 15 seconds after starting ENG 2

65
Q

Before raising the guard on any guarded switch or control, what is required?

A

Confirmation with the other crew member that the current switch or control is selected

66
Q

ECAM procedures require that any Master warning or master caution is

A

Cancelled first, then the title of the abnormal is read out to the Pilot Flying

67
Q

If an engine is damaged the N2 or N3 rotors may be seized or a red spike marker on the EGT gauge may show an exceedance; After confirmation with PF, the Inner tank split switches are turned off for a short period; after confirmation with PF, the

A

FIRE pb is pushed and after 10 seconds the FIRE pb is pushed, if the indication of fire is still on, the Agent 1 DISCH pb is pushed

68
Q

If FADEC fails , what references are there for normal engine operation?

A

Other indications such as hydraulic, electrical, AC or bleed pages must be used to confirm engine status

69
