Aircraft Systems Knowldge (Flight Instruments)

Question 1

In Normal Law what occurs as the aircraft slows to Alpha Prot?

(5 things A ASAP)

Answer 1

1. AOA protection
2. AP disconnects
3. Speed Brakes retract
4. A sidestick behavior changes from load factor demand to AOA proportional to sidestick deflection
5. Pitch trim (nose up) inhibited

Question 2

What protection occurs at a predetermined AOA between Alpha Prot and Alpha Max?

Answer 2

A. Floor protection engages. A/THR provides TOGA thrust regardless of thrust lever position… provided A/THR is available/ operable.

Although A. Floor can engage at any airspeed, it will certainly engage beween Alpha Prot and Alpha Max.

Question 3

What does Alpha Max represent?

Answer 3

The speed corresponding to the maximum AOA that the aircraft can obtain in Normal Law.

Question 4

If the Sidestick is held full aft, will Alpha Max be exceeded?

Answer 4

No, Alpha Max cannot be exceeded even if the side stick is pulled and held fully back

Question 5

If the sidestick is held full aft, will the aircraft enter a stall?

Answer 5

No Alpha Max connot be exceeded even if held back.

Question 6

During the approach, in Normal Law, you hear the aural warning, “SPEED, SPEED, SPEED” What does this represent?

Answer 6

Low Energy Warning. Thrust must be incrased, decreasing pitch alone is not enough to recover a positive flight path angle.

Question 7

During your base turn on approach (in Normal Law), you head SPEED SPEED SPEED, what does this represent?

Answer 7

Low Energy, thrust must be increased, decreasing pitch alone is not enough to recover.

Question 8

In alternate law, what will occur as the airspeed approaches Vsw?

Answer 8

With low speed stability, a gentle nose-down command is initiated which attempts to keep the speed from slowing further

Question 9

The aircraft is in Alternate Law…What would occur if the Sidestick is pulled further aft?

Answer 9

The airplane can be stalled in alternate law.

Question 10

What is indicated by the green = sign at the top of the speed tape?

Answer 10

The speed at which Normal Law overspeed protection becomes active

Question 11

With the AP on, A/THR engaged, and the approach phase activated if you push speed what speed will the Auto throttle maintain?

Answer 11

F Speed
