Q

What cautions would illuminate if a RUD PUSH OFF was pushed?

A

RUD PRESS + RUD FULL PRESS

18
Q

Can the rudder be gust locked?

A

No

19
Q

In what positions are the controls gust locked?

A

Elevator down (yoke forward) and ailerons centered

20
Q

What speeds are available for rudder trim adjustment?

A

FAST or SLOW

21
Q

How is the Yaw Damper engaged?

A

Automatically if AP engaged, or manually by pressing Y/D on FGC panel

22
Q

Which Hydraulic system powers the flap?

A

1

23
Q

When selecting flap, when is pressure supplied to the FPU and for how long?

A

When gate lifted on flap lever. 70secs

24
Q

FLAP POWER

A

Less than 1500PSI in the FPU

25
Q

FLAP DRIVE

A

Primary flap drive shaft has failed (Secondary drive under load)

26
Q

What wing is the aileron trim located on?

A

Right

27
Q

What aerodynamic balancing does the tail employ?

A

Horn Balance
Inset hinge
Spring tab (speed sensitive balance tab)
Trim

28
Q

How many trim cables run from the trim wheel to the tail?

A

1

29
Q

How does the AP control pitch?

A

By use of a motor attached to a pulley at the base of the tail connected to the TRIM cable

30
Q

Are pitch and roll disconnects, reconnectable?

A

Yes

31
Q

What powers the aft rudder section?

A

Pushed by rods connected to the Fore rudder

32
Q

What connects the rudder pedals to the rudder?

A

Nothing, a spring provides feel but the rudder is full hydraulic.

33
Q

Where are the rudder actuators loacted?

A

Both in the same place near the base of the rudder (stack one on top of each other)

34
Q

RUD HYDR + consequence?

A

Less than 500PSI to the actuator, RUD FULL PRESS, as the remaining actuator automatically gets the full 3000PSI

35
Q

How are the spoilers connected to the ailerons?

A

via a servo valve connected to the control cables

36
Q

What type of flap is fitted

A

Single slotted fowler flap

37
Q

What systems require flap position?

A

GPWS, STBY Hydraulic pumps, AP compensator, Gear warning horn

38
Q

What mode of the GPWS is “TOO LOW FLAP”

A

4B

39
Q

Outside what range will the flap warning be heard?

A

Less than 5deg or more than 15 for T/O.

40
Q

What is the travel of the rudder with flap 0?

A

12deg L/R

41
Q

What is the travel of the rudder with any flap selected?

A

16deg L, 18deg R
