Q

Name all 6 Normal Law Protections

A
Load factor limitation
Pitch attitude protection
Angle of Attach protection
High speed protection
Bank angle protection
Low energy warning
2
Q

When does Normal Law begin?

End

A

When Ground mode ends after takeoff.
the flight mode is progressively blended in

Stops at 100ft going into Flare Mode.
The reverse process occurs after touchdown.

3
Q

Define Maneuver Load Alleviation (MLA)

A

Redistribute the lift over wing to relieve structural loads on the outer wings
(bending moment)

4
Q

MLA use what flight controls

A

Spoilers 4, 5, 6, and the Ailerons

5
Q

When is MLA active?

A

Aircraft speed above 250
Flaps lever is in the 0 position
Normal or Alternate Law flight mode

6
Q

With sidestick Neutral and wings level

how many Gs does the airplane have

A

With the sidestick neutral and wings level the system maintains a load factor of 1 G

7
Q

When is Pitch Trim Frozen?

A
  1. Manual trim order
    Radio Altitude below 100 ft for flare
    Load Factor is lower that .5g
    High Speed protection
8
Q

In a turn up to 33 degrees, must you hold back pressure on the sidestick

A

NO

Once the turn is established, the sidestick can be released to neutral.

9
Q

What happens in Flare Mode?

A

The flight mode changes to flare mode at landing when passing 100 ft. Flare mode is a direct stick-to-elevator relationship, with some damping provided by load factor and pitch rate feedbacks.

10
Q

What happens at 50 feet in the flare?

A

At 50 feet a slight pitch down elevator order is applied so that the pilot has to move the sidestick rearwards to maintain a constant path, so as to reproduce conventional aircraft aerodynamic characteristics.

11
Q

What happens to the trim on touchdown?

A

Following touchdown, as pitch attitude becomes less than 2.5 ° for more than 5 sec, pitch trim is automatically reset to 4 ° nose up

12
Q

What are Load Factor limitation?

A

Normal load
Slats Retracted +2.5 to -1 g
Slats Extended +2.0 to 0 g

13
Q

When is load Factor displayed?

and Where is it displayed?

A

Load factor is momentarily displayed on the lower ECAM whenever the G load is above 1.4 G, or below 0.7 G

14
Q

What are Pitch Attitude Limitation?

A

Pitch attitude is limited to 30 ° nose up, progressively reduced to 25 ° at low speed, and is limited to 15 ° nose down.
If flying at the nose up limitation, pulling back on the sidestick has no effect. However, full nose down demands are still available.At the nose down limitation, the reverse is true. Pushing further on the sidestick would have no effect, but full nose up authority is still available

15
Q

When are Pitch attitude limits displayed on the PFD as small green horizontal bars

A

When pitch attitude exceeds 25 ° nose up or 13 ° nose down, all PFD displays except attitude, speed, speed trend, heading, altitude and vertical speed disappear.

16
Q

When does the PFD return to normal?

A

when the pitch angle returns to the region between 22 ° up and 10 ° down

17
Q

What Happens Under Normal Law, when the Angle of Attack defined as Alpha Protection or Alpha Prot is reached,

A

the system switches the elevator control from Normal mode to a protection mode in which the Angle of Attack is proportional to the sidestick deflection

18
Q

What happens at Alpha Prot and Alpha Max?

A

In the range between Alpha Prot and Alpha Max, the sidestick commands alpha directly. The autopilot will disconnect if this protection is active

19
Q

What activates
Alpha Prot,
Alpha Max
and A. FLOOR

A

The conditions vary according to weight and configuration.
Alpha Prot and Alpha Max are computed by the PRIM.
A FLOOR logic is provided by the PRIM and is activated through the autothrust system.

20
Q

How is A. Floor activated?

And what will it command?

A

At a critical Angle of Attack, A. FLOOR is activated through the autothrust system. Autothrust will command TOGA thrust regardless of thrust lever position

21
Q

What must be done To leave

Angle of Attack Protection?

A

The sidestick must be pushed more than 8 ° forward,
must be pushed more than 0 ° forward for at least 1 sec (when alpha is less than Alpha Max), must be at neutral or pushed forward (when alpha is less than Alpha Prot)

22
Q

What will you see on the FMA

When the aircraft exits A. FLOOR conditions

A

TOGO LK

23
Q

How do you Cancel the TOGA LOCK

A

the pilot sets the thrust levers to the thrust required and then presses the A/THR instinctive disconnect pb

24
Q

On the PFD airspeed scale what color is
Vls
Alpha Prot
Alpha Max

A

Vls is the top of the Yellow hook.
Alpha Prot is represented by the top end of the black and amber strip,
Alpha Max is represented by the top of the red strip.

25
Q

What happens when High Speed is

activated?

A

the autopilot disconnects, pitch trim is frozen and positive spiral static stability is introduced so that with the sidestick released, the aircraft will always return to wings level
the bank angle limit is reduced from 67 ° to 45° The sidestick nose down authority is progressively reduced and a permanent nose up order is applied to aid recovery

26
Q

Between what altitude is the

Low Energy Warning activated

A

100 ft and 2,000 ft in CONFIG 2, 3 and FULL, a low energy aural warning “SPEED SPEED SPEED” indicates to the pilot that thrust must be increased.

27
Q

In Flight what is the roll rate of the rudder

A

the roll rate requested by the pilot is proportional to the sidestick deflection up to a maximum of 15 °/sec.

28
Q

What 2 protections limit the bank angle to 45 degrees

A

If Angle of Attack Protection or High Speed Protection is active.

Autotrim is inoperative and the system maintains positive spiral static stability so that with the sidestick released, the aircraft returns to wings level

29
Q

In Alternate Law

Is High Angle of Attack protection is lost?

A

YES

30
Q

Is Bank Angle protection lost in ALT 2 Law

A

YES

No Autopilot
No Yawing damping
No Turn Coordination
