Flight Controls

Question 1

The Stabilizer is powered from which hydraulic system? AOM II 9-16

Answer 1

2 & 3

Question 2

When are the Stab Trim switches on the control wheel inhibited? AOM II 9-17

Answer 2

When multiple autopilots are engaged

Question 3

When do Outboard Ailerons unlock? AOM II 9-18

Answer 3

Flaps are out of UP or airspeed low (locked with flaps up and airspeed high)

Question 4

What is the AUTO position on the Stab Trim Cutout switch for? AMO II 9-16

Answer 4

Allows auto cutout if unscheduled stab trim is detected.

Question 5

With the Speedbrake in ARM , when do the Speedbrakes deploy on landing? When NOT armed? AOM II 9-22

Answer 5

Armed; Thrust Levers 1 & 3 near the closed position and Main Gear touch down.
Not Armed; Thrust levers 1 & 3 near the closed position and Reverse Levers 2 & 4 reverse idle.

Question 6

What flap protection is provided in secondary mode? AOM II 9-25

Answer 6

TEF Asymmetry only. (Not flap load relief)

Question 7

What will occur if the trailing edge flap (TEF) group is in the secondary mode with hydraulic pressure available? AOM II 9-24

Answer 7

TEF will be driven electrically instead of hydraulically (much slower). They will remain in secondary mode until fully retracted.
LEF - stay in Secondary mode until reaching selected position.

Question 8

In the alternate control mode, how is flap extension sequenced? AOM II 9-25

Answer 8

All Leading and Trailing Edge flap groups begin to extend immediately (simultaneously).
TEF extends to a maximum position of Flaps 25.
During retraction, all LEF groups retract after the inboard TEF are completely retracted.

Question 9

On landing, why does the flap position indicator change from green to magenta? AOM II 9-25

Answer 9

Due to inboard and mid-span LEF retracting when reverse thrust is commanded.

Question 10

What is the max altitude for flap extension? AOM I L-16

Answer 10

FL200
