2 / 15

When are pitch trim changes required with the 777 'fly-by-wire' system?

During airspeed changes only.

When thrust is changed.

For all configuration changes.

When the landing gear is extended.

3 / 15

Which statement is true when the primary flight computer disconnect dwitch is positioned to DISC?

Protection features are NOT available.

Autopilot is not available.

The system operates in direct mode.

All of the above.

4 / 15

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

Control wheel pitch trim switches.

Both of the above.

Alternate pitch trim levers.

None of the above.

5 / 15

What is the effect of placing a stabilizer cutout switch to cutout?

Disable direct rudder control.

Disconnects hydraulic supply to STCM.

Connects hydraulic supply to STCM.

Engages gust suppression.

6 / 15

What control do the flaperons and ailerons provide?

Yaw control assisted by the rudder.

Pitch control assisted by a movable horizontal stabilizer.

Roll control assisted by asymmetric spoilers.

Increased wing lift and decreased stall speed.

7 / 15

Which of the following is not a stall protection feature?

Use of alternate pitch trim levers reduces the column forces below the minimum manoeuvring speed.

The out-of-trim forces increase above normal for a condition above the minimum manoeuvre speed.

The pilot must apply continuous aft column force to maintain airspeed below the manoeuvring speed.

Stab trim is inhibited in the nose up direction at approximately the minimum manoeuvring speed.

8 / 15

What is the meaning of the EICAS advisory message STABILIZER CUTOUT?

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

Stabilizer asymmetry compensation is inoperative.

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

The centre stabilizer control path is inoperative

9 / 15

What is true about turn compensation?

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.

It is available only in the secondary mode.

10 / 15

What is FALSE about stabilizer trim?

As airpseed increases, trim rate increases.

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

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

As airspeed increases, trim rate decreases.

11 / 15

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

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

Take-off, rejected take-off and approach.

Take-off, rejected take-off and landing.

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

12 / 15

Direct control surface deflection.

Electric signals.

Mechanical linkage.

13 / 15

Primary Flight Computers (PFCs)

Actuator Control ElectronicS (ACES)

All components are operating?

Electro hydraulic servos.

14 / 15

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

No the ailerons are used only at high speed

Yes the ailerons move down with flaps 15 and 20.

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

15 / 15

Spoilers 1 to 7

Spoilers 8 to 14

Spolers 5 and 10

Spoilers 1 and 14
