Q

Where do you extend slats and what are their postions

A

UP/RET and EXT

19
Q

Where is the Stablizer trim displayed

A

Configuration SD and Secondary Engine SD Synoptic

20
Q

How is Horizontal stab trim controlled……

A

By the primary trim switches, the alternate trim switches or the autopilot

21
Q

What are the primary trim switches on the control wheel for…..

A

For manual stab timming at a faster rate

22
Q

What are the alternate trim switches (ALT LONG TRIM) on the pedistal used for….

A

For manual stabilizer trimming at a reduced rate

23
Q

How does the autopilot trim the airplane

A

Alternate trim system

24
Q

How is the stablizer trimmed with the primary trim switches….

A

When the trim switches are moved together, the trim moves in the commanded direction

Seperate movement of the switches will not command movement

25
Q

What does the stab movement warning horn do….

A

Alerts the crew any time the stab moves more than 1 degree and continues following each degree.

The stabilizer motion voice warning also sounds.

Both are inhibited on the ground

26
Q

What does the STABILIZER TRIM switch do….
NORMAL
OFF

A

NORMAL- OFF light is extinguished and primary stab trim is enabled

OFF- (Switch is pushed) Amber off illuminates and electrical power to the brake is removed, setting the brake eto prevent stabilizer movement.

27
Q

How are the elevators positioned for pitch control….

A

Elevators are aerodynamically positioned by control tabs, which are mechanically connected to the control columns

A variable load feel mechanism simulates aerodynaically forces anbd returns the control column to an artificial center postion when they are released

28
Q

What are the two elevator tabs….

A

Control Tabs - Operated by the control columns, then aerodynamically postion the elevators

Geared Tabs - As the elevator is moved, geared tabs are deflected, providing aerodynamically assitance is moving the elevators.

29
Q

How many control tabs are on the elevators

A

4, two on each side

30
Q

How is pitch controlled maintained in the event of a control jam……

A

Brake the torque tube with 130 lbs of pressure to make the column operate independently

Maintenace is required opnce disconnected

31
Q

What does the Elevator Augmentation System consists of….

A

Two hydraulic boost cylinders that augment elevator control during a deep stall recovery, providing additional nose down capability

32
Q

Where does the Elevator Augmentation System get is power from……

A

Left hydraulic system with an accumulator backuo in the event of a loss of pressure

33
Q

What happens when the elevator augmentation system is activated by pushing the control wheel down

A

Elevators move to full defelection, trailing edge down

34
Q

What is the function of the spoilers (3)

A
  1. Roll Augmentation
  2. Speed Brakes
  3. Decrease lift and increase drag on rejected takeoff or landing roll
35
Q

How are spoilers controlled…..

A

Electricall controlled by Spoiler Electronic controk unit and hydraulically powered.

36
Q

How is roll control accomplished using ailerons and spoilers……

A

Ailerons are aerodynamically posistioned by control tabs mechanically connected to the control wheel

Aerodynamic forces on the control tabs position the ailerons

37
Q

How are the ailerons trimmed…..

A

Trim tab outboard of the control tab on eahc aileron

38
Q

What happens with more than 5 degrees of control wheel input……..

A

The flight spoilers extend a proportionate amount on the downward moving wing for greater roll

39
Q

What doe the AILERON TRIM switches do

A

Operate the trim tabs for LEFT WING DOWN/RIGHT WING DOWN control

40
Q

How is roll control maintained with a control wheel jam….

A

Linked with a torque tube and an overide mechanism.

In the event on control or cable system becomes jammed, roll control is still possiblewith the other control tab by overriding the jammed component

41
Q

When will ground spoilers auto deploy………

A

Rejected takeoff or on landing roll if

42
Q

What conditions allow the spoilers to auto deploy

A

Switch in AUTO and…….

Reverse thrust is selected in a rejected takeoff
When landing, main wheel spin-up or a ground shift signal from the nose gear deploys the spoilers.

43
Q

In the event of a stall what does the stick pusher do…..

A

STICK PUSHER PUSH TO INHIBIT LIGHT illuminates.

Auto pilot if in use, disconnects

Abrupt forward movement of both control columns occurs, followed by stick shacker deactivation

Forward pressure on the control columns continues until AOA is reduced below stick shacker or the STICK PUSHER PUSH TO INHIBIT BUTTON IS PUSHED

44
Q

Does the flight crew have to ability to override the stick pusher?

A

Yes, by pushing the switchlight.

Can manually be overridden by pulling on the control column. If the stall still exist, the sitck pusher will force the column over again.
