Q

What are the memory items for a Roll Malfunction?

A

Hold wings level,
If either SPLR push off lights on - press
if not increase power+speed (more control with more airflow)

Q

What is the function of the rudder pressure regulator?

A

To provide more control at slower speeds by regulating the pressure in the actuators from 900PSI up to 1500PSI below 150kts

18
Q

Can the rudder be gust locked?

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?

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
FLAP DRIVE
Primary flap drive shaft has failed (Secondary drive under load)
26
What wing is the aileron trim located on?
Right
27
What aerodynamic balancing does the tail employ?
Horn Balance Inset hinge Spring tab (speed sensitive balance tab) Trim
28
How many trim cables run from the trim wheel to the tail?
1
29
How does the AP control pitch?
By use of a motor attached to a pulley at the base of the tail connected to the TRIM cable
30
Are pitch and roll disconnects, reconnectable?
Yes
31
What powers the aft rudder section?
Pushed by rods connected to the Fore rudder
32
What connects the rudder pedals to the rudder?
Nothing, a spring provides feel but the rudder is full hydraulic.
33
Where are the rudder actuators loacted?
Both in the same place near the base of the rudder (stack one on top of each other)
34
RUD HYDR + consequence?
Less than 500PSI to the actuator, RUD FULL PRESS, as the remaining actuator automatically gets the full 3000PSI
35
How are the spoilers connected to the ailerons?
via a servo valve connected to the control cables
36
What type of flap is fitted
Single slotted fowler flap
37
What systems require flap position?
GPWS, STBY Hydraulic pumps, AP compensator, Gear warning horn
38
What mode of the GPWS is "TOO LOW FLAP"
4B
39
Outside what range will the flap warning be heard?
Less than 5deg or more than 15 for T/O.
40
What is the travel of the rudder with flap 0?
12deg L/R
41
What is the travel of the rudder with any flap selected?
16deg L, 18deg R
