1 / 15

What power source is used for the actuation of all primary flight controls?

Pneumatic.

Electric.

Mechanical.

Hydraulic.

2 / 15

What happens if uncommanded stabilizer motion is sensed?

The A/P engages automatically.

Power to the affected STCM is shut off.

The stabilizer is locked in place.

Power to all STCMs is shut off.

3 / 15

When do the control wheel stabilizer trim switches control stabilizer movement directly?

All the time.

Only on the ground.

During engine out go-arounds.

4 / 15

What is wheel to rudder cross-tie?

Ability to control rudder trim with control wheel inputs.

Ability to control initial effects of an engine failure with control wheel only.

Ability to dampen dutch roll with control wheel only.

Ability to override rudder inputs with the control wheel inputs.

5 / 15

Which trim control(s) are inhibited when the autopilot is engaged?

None of the above.

Alternate pitch trim levers.

Control wheel pitch trim switches.

Both of the above.

6 / 15

What is true about turn compensation?

It is available only in the secondary mode.

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

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

The turn compensation switch is on the overhead panel.

7 / 15

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

Both of the above.

Control wheel pitch trim switches.

Alternate pitch trim levers.

8 / 15

What is FALSE about stabilizer trim?

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

As airpseed increases, trim rate increases.

As airspeed increases, trim rate decreases.

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

9 / 15

Which one of the following statements is incorrect?

The spoilers augment roll control.

Spoilers 4 and 11 are mechanically operated.

Spoilers 5 and 10 are available as ground spoilers only.

The extension of speed-brakes in the landing configuration is prohibited.

10 / 15

In direct mode, which of the following components of fly-by-wire are NOT operating?

Position feedback transducers.

Actuator Control ElectronicS (ACES).

Primary Flight Computers (PFCs).

Power Control Units (PCUs).

11 / 15

Are the PFCs and ACEs used in direct mode?

Only PFCs

Only ACEs

It is not possible.

Both PFCs and ACEs

12 / 15

Auto speed-brakes protection is provided for which phases of flight?

Take-off, rejected take-off and landing.

Take-off, rejected take-off and approach below 200 feet.

Take-off, rejected take-off, approach and landing.

Take-off, rejected take-off and approach.

13 / 15

What is FALSE about Flap/Slat Load Relief?

Re-extension is limited to the commended flap position.

Flap load relief is available in the primary and secondary modes.

The Flap lever does not move during flap condition and shows actual flap position.

When airspeed is reduced the flap automatically re-extend as airspeed allows.

14 / 15

What principle is used when direct mode is in use?

Electric signals.

Hydraulic signal modulation.

Direct control surface deflection.

Mechanical linkage.

15 / 15

Do the ailerons increase lift for takeoff?

Yes the ailerons move down with flaps 15 and 20.

Yes the ailerons move down with flaps 5, 15 and 20.

No, the ailerons assist roll control only during high speed flight.

No the ailerons are used only at high speed
