23
Q

Can the auto pilot be engaged without a functioning yaw damper?

A

No

24
Q

The automatic flight control system operates servos to control the aircraft with the auto pilot engaged. Which control surface does not have a servo?

A

150 KT

26
Q

What is the maximum flap operating altitude?

A

15,000 feet

27
Q

In-flight, the spoiler 1 push off switch light illuminates what does this mean?

There is a jam in the inboard roll spoiler actuator linkage.

28
Q

What is the maximum flap extension speed for flap 5 in a Dash 8 300?

A

163 KT

29
Q

In the 300, deflection of the ailerons is assisted by what?

A

Geared tabs

30
Q

In the event of a number 2 hydraulic system malfunction resulting in a total system pressure loss, which of the following maybe expected of the roll control system?

A

Illumination of the roll spoiler outboard hydraulic caution light when the indicated airspeed drops below 140 KT

31
Q

A roll spoiler cable circuit jam, which cannot be overcome with a overpowering force, will require which of the following actions?

A

ROLL DISC handle pulled and turned 90°

32
Q

If hydraulic pressure operating the flap power unit drops below 1500 psi which caution light will illuminate?

A

FLAP POWER

33
Q

What function does the roll spoiler clutch assembly serve?

A

Prevents a jam in a roll spoiler actuator linkage from immobilising the whole roll spoiler control system.

34
Q

Spoiler 1 illuminates for a jam In which actuator linkage?

A

Inboard roll spoilers.

35
Q

How far do the spoilers extend under normal conditions?

A

75% of full travel

36
Q

When is full roll spoiler travel available?

A

When the roll disc handle has been used

37
Q

Maximum fore Rudder travel is What ?

A

16° left, and 18° right

38
Q

Fore rudder travel limits with flaps zero?

A

12°

39
Q

How much authority does the rudder trim have?

A

10° either side of centre

40
Q

Rudder pressure regulation above 150 kn and below 150 kn ?

A

Below 150 kts Is 1500 psi above 150 kts is 900 psi

41
Q

Should either rudder actuator fails what occurs?

A

The rudder pressure regulator automatically admits full hydraulic system pressure at 3000 PSI

42
Q

What is used to provide data to the yaw damper system?

A

Accelerometers within the flight guidance computer provide yaw data

43
Q

How far can the yaw damper move the rudder?

A

5° left or right of an existing rudder setting

44
Q

VFE Flap 35?

A

138kts

45
Q

VFE Flap 10 300 ?

A

154kts

46
Q

VFE Flap 35 200 ?

A

130kts

47
Q

VFE Flap 5 200 ?

A

148kts

48
Q

The left elevator is
controlled by fore and aft
movement of the ?

A

of the pilot’s

control column,

49
Q

The control columns are

mounted at each end of a ?

A

Torque tube

50
Q

Elevator trim is provided by

tabs on each surface located ?

A

outboard of the spring tabs.

51
Q

A hydraulic rudder damper

restricts ?

A

rapid movement of the
rudder from wind gusts while
the aircraft is parked without
hydraulic power.

52
Q

Operation of the trigger

energises open the ?

A 
the FPU
Isolation Solenoid Valve for 70
seconds. The isolation solenoid
valve admits hydraulic pressure
to the FU and provides
sufficient time to complete the
positioning of the flaps.
53
Q

A load torque sensor is
installed on the secondary
shaft to detect conditions in
which ?

A

to detect conditions in

which it is driving under load.

54
Q

The maximum flap operating altitude is ?

A

15,000ft
