The green band on the indicator turns amber.

The CDU displays the VERIFY TRIM message in the scratchpad.

The EICAS message STAB GREENBAND displays.

2 / 15

What is the correct statement?

Moving the alternate pitch trim levers with the autopilot engaged does not move the stabilizer.

All statements are correct.

Aileron trim in inhibited when the autopilot is engaged.

Moving the alternate pitch trim levers during stall or overspeed protection does not move the stabilizer

3 / 15

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

Connects hydraulic supply to STCM.

Disable direct rudder control.

Engages gust suppression.

Disconnects hydraulic supply to STCM.

4 / 15

When do the PFCs make self-test?

After hydraulic system pressurization.

After hydraulic system depressurization.

After the "PRIMARY FLIGHT COMPUTERS" EICAS message is displayed.

After hydraulic system shutdown (HYD PRESS SYS L+C+R).

5 / 15

What could cause the STAB GREENBAND EICAS message to be displayed?

Power to the stabilizer position indicator is lost.

The stabilizer position indicator is unreliable.

The FMC weight entry and CG may be incorrect.

All statements are correct.

6 / 15

Which of the following is not a stall protection feature?

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

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.

7 / 15

Which control surfaces are used for roll control on the B777?

Ailerons, flaperons and flaps.

Ailerons, flaperons and spoilers.

Ailerons, flaperons and slats.

Ailerons, flaperons and elevators.

8 / 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.

9 / 15

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

Alternate pitch trim levers.

Control wheel pitch trim switches.

Both of the above.

10 / 15

What is FALSE about stabilizer trim?

As airspeed increases, trim rate decreases.

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

As airpseed increases, trim rate increases.

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

11 / 15

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

220 knot.

200 knot.

210 knot.

180 knot.

12 / 15

What is FALSE about Flap/Slat Load Relief?

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

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

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

Re-extension is limited to the commended flap position.

13 / 15

Do the ailerons increase lift for takeoff?

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

Yes the ailerons move down with flaps 15 and 20.

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

No the ailerons are used only at high speed

14 / 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

The EICAS message STAB GREENBAND displays

15 / 15

Which spoilers will be locked out in secondary and direct modes?

Spoilers 8 to 14

Spolers 5 and 10

Spoilers 1 and 14

Spoilers 1 to 7
