The centre stabilizer control path is inoperative

One stabilizer cut-out switch is in the CUTOUT position.

Stabilizer asymmetry compensation is inoperative.

Both stabilizer cut-out switches are in the CUTOUT position.

4 / 15

Automatic speed-brake operation is provided for which flight control system modes?

All flight control modes.

Direct.

Normal.

Secondary.

5 / 15

What is true about turn compensation?

Elevator input is NOT required if the airplane is in a 30 degree bank.

It is not available if the bank angle is above 30 degrees.

It is available only in the secondary mode.

The turn compensation switch is on the overhead panel.

6 / 15

What is the status of the crew oxygen system if the oxygen status display is blank?

Alternate pitch trim levers.

Both of the above.

Control wheel pitch trim switches.

7 / 15

What is FALSE about stabilizer trim?

As airpseed increases, trim rate increases.

The green band on the stabilizer position indicator shows the stabilizer trim range for takeoff.

As airspeed increases, trim rate decreases.

You can use the pitch trim switches on the yoke to set the trim.
