Protections and Stabilities 2

Question 1

In alternate law, and if available, at what speed is low speed stability active?

Answer 1

5-10kt above VSW

Answer 2

Nose up 30 degrees (CONF 0-3) and 25 degrees CONF FULL. Progressively reduced by 5 degrees at low speeds.
Nose down 15 degrees in all cases

Question 3

In direct law, what config is needed for landing and what speed adjustment if any?

Answer 3

CONF 3 and VREF + 10kt for landing unless otherwise specified

Question 4

Answer 4

Speed less than or equal to 100kts

Question 5

What is an easy way to identify if you are in alternate law?

Answer 5

MMO +0.04

Question 7

At what angle of bank do the FDs reappear after overbanking?

Answer 7

40 degrees

Question 8

If ECAM states F/CTL ALTN LAW (PROT LOST), are protections lost?

Answer 8

Load factor protection is retained. High and low speed stabilities may be retained, but ECAM doesnt tell us

Question 9

In alternate law, is high speed stability available?

Answer 9

It might be, depending on the situation

Question 10

Max 40 degrees AOB

If sidestick released, bank angle returns to 0

Question 11

In flight mode, what does the sidestick command?

Answer 11

In pitch, load factor demand, and in roll a roll rate demand

Question 12

With stick neutral, what will speed decay until?

Answer 12

ValphaProt

Question 13

In alternate law, what does the sidestick command?

Answer 13

In pitch it is normal - Load factor demand with auto pitch trim
In roll, it is a direct relationship. Maximum is 30 degrees per second clean or 25 degrees per second with flaps

Question 14

Where on the speed tape is VSW?

Answer 14

Top of the barber pole

Question 15

At what attitude do FDs disappear in normal law? When are they recovered?

Answer 15

25 degrees up, 13 degrees down.

Recovered at 22 degrees up and 10 degrees down

Question 16

What is the high speed protection bank angle limit?

Answer 16

40 degrees

Question 17

What is the maximum bank angle?

Answer 17

67 degrees

Question 18

What is shown at the low speed end of the speed tape in alternate law?

Answer 18

The barbers pole and the amber hockey stick only

Question 19

Answer 19

1. Normal law
2. Alternate law
3. Direct law
4. Mechanical Backup
5. Abnormal attitude

Question 20

In alternate law, is alpha floor available?

Answer 20

No

Question 21

What causes mechanical backup?

Answer 21

Loss of multiple flight control computers or flight control surfaces, or total but temporary electrical loss

Question 22

Answer 22

Pitch - direct
Roll - direct
