Which of the following is indicated by the EICAS caution message STAB TRIM UNSCHD?

Answer 21

Stab movement without trim signal

Question 22

What will happen when the stabilizer trim switches on the control wheels are actuated with multiple autopilots engaged?

Answer 22

Nothing - They are inhibited during autoland (Multiple A/P use) (Two actuators are used so stab moves at NORMAL TRIM rate)

Question 23

What occurs when the alternate stabilizer trim switches are used with any number of autopilots engaged?

Answer 23

Override A/P trim inputs but do not disengage A/P. Pilot is warned via a STAB TRIM UNSCHD caution msg.Will override the A/P input ()

Question 24

Which hydraulic systems power the stabilizer trim?

Answer 24

2 and 3

Question 25

What occurs when the stabilizer trim switches on the control wheel are actuated with a single autopilot engaged?

Answer 25

A/P is disengaged ()

Question 26

Which trim is affected by the control column cutoff function?

Answer 26

STAB Trim (FCOM 9.20.5)

Question 27

Hydraulic power for the elevators is provided by which hydraulic systems?

Answer 27

1,2,3,4…... ## Footnote Hyd 1 - Left outboard Hyd 4 - Right outboard Hyd 1&2 - Left inboard Hyd 3&4 - Right inboard

Question 28

What stabilizer trim condition exists when both stabilizer trim cutout switches are in the cutout position?

Answer 28

Hydraulic power is shut off. ()

Question 29

Why are the outboard ailerons locked out?

Answer 29

To prevent overcontrolling at high airspeeds and provides the required roll authority at low airspeeds. (lock in neutral position at 238kts) (FCOM 9.20.7)

Question 30

What does the aileron trim indicator display?

Answer 30

Aileron Trim units (The trim deflects the control wheel in a desired direction, the indicator shows the amount of deflection)

Question 31

What is one of the required conditions for automatic speedbrake extension with the speedbrake lever in the ARM position?

Answer 31

Main gear on ground Thrust levers 1 and 3 near idle (FCOM 9.20.11)

Question 32

Which statement is true when the EICAS advisory message SPEEDBRAKE AUTO is displayed?

Answer 32

Speedbrakes can still be operated manually

Question 33

How many spoiler panels are on each wing?

Answer 33

6 (similar to question 195)

Question 34

With the speedbrake lever in the armed position what does the EICAS message speedbrake auto mean?

Answer 34

Fault detected in automatic ground spoiler system that could result in an inadvertent spoiler extension (FCOM 9.30.1)

Question 35

When are the outboard ailerons locked out?

Answer 35

High airspeed ()

Question 36

What is the function of the RUDDER RATIO changers?

Answer 36

Limit deflection with increasing speed. 1. Gradually reduce each rudder surface's response to pedal inputs as airspeed increases. 2. Protects the vertical tail structure from stresses which could result from large rudder surface deflections at high airspeeds (FCOM 9.20.9)

What does the rudder trim indicator display?

Answer 41

Units of rudder trim (towards nose left or nose right) ()

Question 42

What does rotating the rudder trim knob do?
