1 / 15

What happens when the stabilizer signal is not present or is invalid?

The green band on the indicator turns amber.

The CDU displays the VERIFY TRIM message in the scratchpad.

The green band and the pointer are not displayed.

2 / 15

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

During airspeed changes only.

When thrust is changed.

When the landing gear is extended.

For all configuration changes.

3 / 15

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

All the time.

Only on the ground.

All the time.

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 override rudder inputs with the 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.

5 / 15

Auto speedbrakes protection is provided for which phases of flight?

Takeoff, rejected takeoff and approach below 200 feet.

Takeoff, rejected takeoff and landing.

Takeoff, rejected takeoff, approach and landing.

Takeoff, rejected takeoff and approach.

6 / 15

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

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

The centre stabilizer control path is inoperative

Stabilizer asymmetry compensation is inoperative.

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

7 / 15

Which pair of spoilers is mechanically controlled through a cable from the control wheel?

Spoilers 5 and 8.

Spoilers 4 and 11.

Spoilers 1 and 14.

Spoilers 5 and 10.

8 / 15

What does stall warning consist of?

EICAS message 'STALL'.

Stall warning horn.

Stick shaker but NO stall warning.

Stick shaker followed by stall warning.

9 / 15

What does the EICAS message FLIGHT CONTROL MODE indicate?

Multiple flight control surfaces are inoperative.

Flight control system is operating in the secondary mode.

The Flap/Slat electronics units are inoperative.

Flight control system faults are detected.

10 / 15

What is the maximum speed of wheel to rudder cross-tie operation?

220 knot.

180 knot.

210 knot.

200 knot.

11 / 15

What is FALSE about Flap/Slat Load Relief?

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

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

Re-extension is limited to the commended flap position.

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

12 / 15

What principle is used when direct mode is in use?

Hydraulic signal modulation.

Direct control surface deflection.

Mechanical linkage.

Electric signals.

During speedbrake extension or retraction.

During airspeed changes.

All statements are correct.

14 / 15

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

When thrust is changed.

For all configuration changes.

When the landing gear is extended.

During airspeed changes only.

15 / 15

Spoilers 1 to 7

Spolers 5 and 10

Spoilers 1 and 14

Spoilers 8 to 14
