Flight Control Laws

Front 1

What protection do you have in Normal Law?

Back 1

- Load Factor Limitation (+2.5/-1)

- Pitch Attitude (30 degrees UP/15 degrees DN)

- Bank Angle (67 degrees)

- High Speed

- High AOA (AOA Alpha Protection)

Front 2

How does the High Speed Protection operate?

Back 2

If Vmo/Mmo plus a predetermined factor is exceeded, the system induces a pitch-up input to limit aircraft speed

Front 3

Can the pilot override the auto pitch-up associated with High Speed Protection in Normal Law?

Back 3

No

Front 4

What is Alpha Max?

Back 4

The maximum AOA allowed in Normal Law, indicated by the top of the red strip on the airspeed scale

Front 5

How does High AOA Protection operate?

Back 5

When the angle of attack exceeds alpha prot, pitch trim ceases and AOA is now proportional to sidestick deflection, not to exceed alpha max even with full aft sidestick deflection.

Front 6

What protection do you have in Alternate Law?

Back 6

- Load Factor Stability

- High speed stability (Nose up command)

- Low speed stability (Nose down command)

Front 7

Can you override the high or low stabilities in Alternate Law?

Back 7

Yes

Front 8

What protections do you have in Direct Law?

Back 8

None

Front 9

If you are in Pitch Alternate Law, what law would Roll be?

Back 9

Direct Law

Front 10

When the landing gear is extended, what happens to Pitch Alternate Law?

Back 10

Degrades to Pitch Direct Law

Front 11

When is there a direct relationship between sidestick and flight control surface deflection?

Back 11

- When in Normal Law Ground Mode

- When in Direct Law

- When below 50' in Flare Mode (Pitch Only)

Front 12

How would you get into Abnormal Attitude Law?

Back 12

By exceeding approximately double the Normal Law limits

Front 13

Can you stall the aircraft in Normal Law?

Back 13

Not in Normal Law, but the aircraft CAN be stalled in other laws

Front 14

What is the purpose of Abnormal Attitude Law?

Back 14

Allows the aircraft to be recovered from an unusual attitude

Front 15

After recovery from an unusual attitude, what law will you be in?

Back 15

Abnormal Attitude Law

Front 16

Will Abnormal Law revert to Direct Law on landing gear extension?

Back 16

No

Front 17

What PFD indications indicate Normal Law?

Back 17

- Green "=": for pitch, bank, and overspeed limits

- Amber/Black (alpha prot) airspeed tape

Front 18

What is indicated if the PFD pitch and bank limits are amber Xs?

Back 18

You are not in Normal Law

Front 19

How is Direct Law indicated on the PFD?

Back 19

Amber "XX"

"USE MAN PITCH TRIM" on top of PFD

Front 20

What would cause you to revert to another law?

Back 20

Multiple failures of redundant systems

Front 21

What law are you in when you perform the flight control check on the ground?

Back 21

Normal Law, Ground Mode

Front 22

Can the aircraft be flown with a loss of all flight control computers?

Back 22

Yes, in Mechanical Backup

Front 23

How is Mechanical Backup indicated on the PFD?

Back 23

"MAN PITCH TRIM ONLY" on top of PFD

Front 24

How is the airplane controlled in Mechanical Backup?

Back 24

- PITCH: Trim Wheel (horizontal stabilizer)

- YAW: Rudder Pedals (Rudder)

- SPEED: Thrust Levers

Front 25

When operating in Normal Law in Flight Mode, what does the side stick command for pitch and roll?

Back 25

Pitch: G Load

Roll; Roll Rate

Front 26

In Normal Law, when descending through 50 feet on landing, the aircraft pitch is memorized. What happens when descending through 30 feet?

Back 26

"Flare Mode"

Aircraft pitches down to make pilot flare.
