9 - Flight Controls

Question 1

When will the leading edge slats be:
A: Extended
B: Fully extended

Answer 1

A: TE flaps 1-5
B: TE flaps >5

Question 2

What does the stabilizer trim override switch do

Answer 2

When the control column/pilot is moving the control column in the opposite direction of trim (fighting the trim= cutout switches will stop trim motion.
The STAB TRIM override switch will restore trim capabilities

Question 3

If the AUTO SLAT FAIL light illuminates during recall, what has happned

Answer 3

A single SMYD (Stall Management Yaw Dampener) computer has failed

Question 4

How many flight and ground spoilers are there on each wing?

Answer 4

2 ground spoilers 4 flight spoilers on each wing

Question 5

Will the LE FLAPS TRANSIT light illuminate during autoslat operation?

Answer 5

No

Question 6

When will the LE FLAPS TRANSIT light illuminate?

Answer 6

• Any LE device in transit
• Any LE device not in programmed position in regards to TE flaps
• two or more LE flaps or slats have moved away from their commanded position

Question 7

Autoslats are powered by system B. What happens if system B loses pressure?

Answer 7

The autoslats can still be powered by the PTU, which in turn is powered by System A

Question 8

What is the control column elevator jam override function

Answer 8

With enough force, the two pilot’s control columns can be separated, and still function (one of them), in an elevator jam situation

Question 9

Does the main stabilizer and autopilot trim system use different motors?

Answer 9

No, they use the same motor

Question 10

The FSEU provides which protections?

Answer 10

• Flap load relief with flaps in 30 or 40
• Asymmetry and skew conditions
• Indications for uncommanded position of TE or LE devices. Will stop the motion if two or more LE slats or flaps move uncommanded, or the TE flaps move uncommanded

Question 11

If hydraulic system A and B are lost, what will power the flight controls?

Answer 11

Stby system will power rudder, ailerons and elevator will be by manual reversion

Question 12

How many LE slats and flaps are located on each wing?

Answer 12

4 slats 1 flap

Question 13

What will happen to the yaw dampener if hydraulic system B is lost?

Answer 13

It will not function

Question 14

Can the yaw dampener be overridden?

Answer 14

Yes, using either the rudder pedals or rudder trim

Question 15

What is the elevator feel system, and how does it work

Answer 15

A computer that uses airspeed from the elevator pitots, and stabilizer position to create a simulated aerodynamic load.
Uses either system A or B pressure, whichever is higher.

Question 16

What does the FEEL DIFF PRESS light indicate

Answer 16

The elevator feel system is sensing an excessive differential pressure.
Usually due to a pitot system or hydraulic system failure.
