Flight Controls

Question 1

Name all 6 Normal Law Protections

Answer 1

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

Question 2

When does Normal Law begin?

End

Answer 2

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.

Question 3

Define Maneuver Load Alleviation (MLA)

Answer 3

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

Question 4

MLA use what flight controls

Answer 4

Spoilers 4, 5, 6, and the Ailerons

Question 5

When is MLA active?

Answer 5

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

Question 6

With sidestick Neutral and wings level

how many Gs does the airplane have

Answer 6

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

Question 7

When is Pitch Trim Frozen?

Answer 7

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

Question 8

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

Answer 8

NO

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

Question 9

What happens in Flare Mode?

Answer 9

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.

Question 10

What happens at 50 feet in the flare?

Answer 10

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.

Question 11

What happens to the trim on touchdown?

Answer 11

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

Question 12

What are Load Factor limitation?

Answer 12

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

Question 13

When is load Factor displayed?

and Where is it displayed?

Answer 13

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

Question 14

What are Pitch Attitude Limitation?

Answer 14

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

Question 15

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

Answer 15

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.

Question 16

When does the PFD return to normal?

Answer 16

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

Question 17

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

Answer 17

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

Question 18

What happens at Alpha Prot and Alpha Max?

Answer 18

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

Question 19

What activates
Alpha Prot,
Alpha Max
and A. FLOOR

Answer 19

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.

Question 20

How is A. Floor activated?

And what will it command?

Answer 20

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

Question 21

What must be done To leave

Angle of Attack Protection?

Answer 21

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)

Question 22

What will you see on the FMA

When the aircraft exits A. FLOOR conditions

Answer 22

TOGO LK

Question 23

How do you Cancel the TOGA LOCK

Answer 23

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

Question 24

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

Answer 24

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.

Question 25

What happens when High Speed is

activated?

Answer 25

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

Question 26

Between what altitude is the

Low Energy Warning activated

Answer 26

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.

Question 27

In Flight what is the roll rate of the rudder

Answer 27

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

Question 28

What 2 protections limit the bank angle to 45 degrees

Answer 28

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

Question 29

In Alternate Law

Is High Angle of Attack protection is lost?

Answer 29

YES

Question 30

Is Bank Angle protection lost in ALT 2 Law

Answer 30

YES

Question 31

5 things you Don’t have in
DIRECT Law

2 things you do have

Answer 31

No Protections.
No Autopilot
No Yawing damping
No Turn Coordination
No AutoTrim

1. Aural Overspeed Warning
2. Aural Stall Warning
