Q

When will the auto flap retraction happen?

A

At 210kts. Will retract to Conf 1 which in the air is slats only. So if you take-off with 1+F will retract just flaps. If you select Conf 2 in air then accelerate it will retract to Slats only at 210kts.

Will stop automatically.
26
Who has priority if both pilots press take-over button?
Last one to press.
27
How long should you press take-over button for?
40sec, to deactivate other stick so inputs are not added together when released. To activate again one wee press on take-over button.
28

When other pilot releases stick.
29

31
What is Pitch attitude protection?
Small green dashes on PFD from 20-30deg depending on configuration. Nose down at 15deg
32
What does the AoA protection do?
Prevents stalling, optimum performance in extreme manoeuvres such as windshear or EGPWS
33
What is V alpha prot speed?
Top of the amber and black line in normal mode. Speed that the Alpha protection kicks in and side stick defection is now proportional to AoA instead of Load Factor.
34
What is V alpha max?
Max AoA available in normal mode.
35
What calculates VLS?
FAC
36
What is VLS?
1. 13Vs on take-off 1. 23 after 1st flap retraction 1. 28 after clean
37
What is the Low Energy Warning?
Speed x3 Computed by FAC Normal Law 100-2000ft RA in conf 2/3/full not in TOGA.
38
What happens to AP at V alpha prot?
Dissengages
39
If no side stick input at Alpha Prot what will the FCC do?
Maintain V alpha prot by pitching down.
40
How do you override alpha prot?
Pull back side stick, if release it will go back to V alpha prot.
41
When is Alpha floor available?
From lift-off to 100ft RA
42
When will Alpha Floor kick in?
Between alpha prot and alpha max. Depending on configuration.
43
What shows you when high speed protection will be activated?
Green dashes on speed scale.
44
When will you get Overspeed ECAM warning?
Above Vmo+4 | Mmo + 0.006.
45
What happens to AP at overspeed protection.
Dissengages at Vmo +15 Mm0 +0.04
46
What happens to side stick authority at overspeed protection?
Reduces pitch down authority Then apply pitch up to slow you down As soon as below Vmo/Mmo it reverts back to normal.
47
How far above Vmo/Mmo when side stick pitch down is removed?
Vmo +16 Mmo +0.04 May accelerate above this speed though.
48
What happens to Bank angle when in overspeed?
Reduces to 0deg if no sidestick input. (instead of 33) | Limit reduced from 67deg to 40deg
49
Bank angel protection, what happens at 33deg?
Auto trim stops. Need to apply back pressure
50
What is the maximum angle of bank normally?
67deg 45deg if AoA protection 40deg if High Speed Protection
51
What angle of bank will autopilot disengage/FD disapear?
45deg
52
When will the FD bars return after bank >45deg?
Return below 40deg
53
What sets the Beta Target?
FAC
54
What are the three levels of reconfiguration?
Alternate with or without reduced protection Direct Mech backup
55
When does ground mode become active on landing?
5sec after touchdown
56
What is the Alternate Law pitch control in flight mode?
Similar to Normal law, G, but with reduced protections
57
What is the flare mode in alternate law?
Direct Law when you lower the gear.
58
What is the Alternate Law roll control?
Direct Law
59
What is the alternate Law Yaw control
Yaw damping only up to 5deg of deflection.
60
What is the alternate law reduced load factor protection?

61
What is the alternate law reduced pitch attitude protection?
None, will see amber XX next to where green bars would normally be
62
What is the low speed stability in alternate law?
Will still have VLS but black and red bar now to show Vsw Gentle nose down signal around 5-10kts above Vsw Can be overridden Injects a bank angle protection to maintain angle of attack STALL +crickets sound No Alpha Floor Same in all configurations
63
What is the high speed stability in alternate law?
introduces nose up demand above Vmo/Mmo No Green Dashes Still get Overspeed Warning AP out at Vmo/Mmo
64
What is the bank angle protection in alternate law?
None Green dashes replaced by amber xx AP out at 45deg
65
What is alternate law without reduced protections?
No high or low speed protections, only load factor.
66
How will you know in Alternate Law?
FCTL ALTN LAW ECAM | Protections are replaced by stabilities.

Mech backup
69
How will you know if you're in Mech backup mode?
Man pitch trim only red message on PFD.

How do you control lateral in Mech Backup?
Rudder pedals provided at least one hyd system powered.
72
What do the ELACs control?

77
What are Active and Damping mode?
Either hyd actuator 1 or 2 is in active mode and the other in in damping mode. One Hyd actuator controlled by one FCC
78
