Normal Law

Question 1

What are the Normal Law protections

Answer 1

Load Factor
Pitch Attitude
Bank Angle
High Speed
Low Speed

Question 2

What is Load Factor protection

Answer 2

“G” Load is limited:
1. Clean: -1G to +2.5G
2. Dirty: 0G to +2G

Question 3

When is the “G” Load displayed

Answer 3

When above 1.4G and below 0.7G

Question 4

What is the Pitch Attitude protection

Answer 4

1. Pitch up limited to 30* nose up, progressively reduced to 25* nose up at low speed
2. Pitch down limited to 15* nose down

Question 5

What is the Bank Angle protection

Answer 5

1. Up to 33* bank angle is maintained with side stick neutral and Auto Pitch Trim is working
2. Above 33* side stick inputs are needed to maintain bank angle and altitude. If side stick is released, bank angle returns to 33* automatically
3. Bank angle limited to 67*

Question 6

What is High Speed protection

Answer 6

1. Master Warning activates at VMO + 4kts or MMO + 0.006
2. HSP activates at VMO + 6kts
3. Pitch Down authority is reduced to zero
4. AP disconnects at VMO +15kts or MMO + 0.04
5. THS limited between the setting at entry and 11* Nose Up
6. Bank angle limited to 40*
7. Bank angle reduces to zero when side stick released
8. Permanent nose up order is applied

Question 7

What is Low Speed protection

Answer 7

1. Ensures that the aircraft can not be stalled in Normal Law
2. 4 stages
3. VLS is is the lowest selectable speed
4. Alpha Prot, top of amber/black, speed will be maintained if side stick is released
5. If side stick is pulled aft in Alpha Prot, Alpha Floor is activated commanding TOGA regardless of thrust lever position
6. Alpha Max, solid amber, is the speed with the maximum angle of attack allowable

Question 8

What happens when Alpha Prot is activated

Answer 8

1. Autopilot disconnects
2. Side stick directly commands the Angle of Attack with out exceeding Alpha Max
3. Speed brakes if deployed retract automatically
4. Bank is limited to 45*

Question 9

What happens when Alpha Floor is activated

Answer 9

1. Automatically commands TOGA thrust regardless of thrust lever position
2. When the aircraft leaves Alpha Floor conditions, TOGA thrust is locked - TOGA LCK
3. TOGA thrust is maintained until pilot disconnects A/THR and exits TOGA LCK
4. Ball on Stick, Click, A/THR ON, THR LVR into CLB detent
