31
Q

How many flap positions?

A
  1. These include 0, 1, 2, 3, FULL
32
Q

Alpha lock does what?

A

Prevents slats from retracting above a specific speed and AoA limit

33

Where is VLS in direct law?

A

Top of red and black blocks

Top of amber line

34
Q

Priority right take over button gives what indications?

Press and hold for 40secs does what?

A

Red arrow pointing right on CPT side, FO in green on the FOs side and an aural warning.

Locks the other pilot out

35
Q

If you lose all flight computers, what law are you in?

In this law, what control surfaces do you have remaining?

A

Mechanical law

You only have THS and rudder mechanically operating hydraulic valves

36

A

Slat and Flap Control Computer

2 SFCCs

37

41
Q

How many FADECs are there?

A

2 - channel A and B

42
Q

Can the FADEC still operate in the event of a power failure?

A

Yes. The engines have an alternator which powers the FADEC

43
Q

How many igniters are used to start the engine in normal conditions?

After 1 engine start attempt, how many igniters are used to start the engine?

After each start attempt, what is the fuel required to start reduced by as a %?

How many starts will the FADEC attempt in a start sequence?

A

1

2

7%

4

44
Q

Engine start process?

A

LP fuel valve opens
Airflow (engine start valve opens)

50% started and igniters cut off

45
Q

What are the 3 idle engine modes?

A

Modulated, approach, reverse

46
Q

What is modulated idle?

A

In flight when flaps are retracted and on the ground without reverse thrust selected.

It is regulated according to bleed system demand and ambient conditions

47
Q

Approach idle is?

A

Regulated according to aircraft altitude regardless of bleed system demand. Selected in flight when the flaps are extended. It revs slightly higher allowing lower spool up times

48
Q

What is reverse idle?

A

Is selected on the ground. Increases thrust slightly when reverse idle is selected

What’s the time limit for 1 engine TOGA?

A

5 mins

10 mins

Oil burn?

A

0.5 quartz per hour

53
Q

How do the FADEC channels work?

A

1 active channel and another channel standby

54
Q

What is in the HMU?

A

Fuel flow control, fuel hydraulic actuators and over speed protectors

55
Q

FADEC protections?

A

Hot start
Hung start
Wet start (failure to light up)
Surge (stall)

56
Q

Where does thrust come from?

A

N1 (70%)

Turbine (30%)

57
Q

What does the FADEC us to calculate thrust?

A

N1 (fan speed)

58
Q

If you turn off the engine master switch in flight, how does the engine physically shut down?

A

By closing the hi and low pressure fuel

59
Q

Does engine master need confirmation to shut down?

A

Yes

60
Q

Where do you see N1 and N2?

A

E/WD engine warning display

61
Q

What does FADEC mean?

A

Full Authority Dual Engine Control

62
Q

What is the red temp on the engine EGT gauge?

A

950 degrees C

63
Q

Max EGT for MCT?

A

915 degrees C

64
Q

Does MCT have a time limit?

A

No

65
Q

EGT limit when operating MCT? And time limit

A

915 degrees C with no time limit

66
Q

What is the minimum oil temp before takeoff?
