A

Hydraulically

22
Q

At what rate will the autopilot trim the stabilizer?

A

1/2 rate using only one stabilizer Trim control module.

23
Q

Stabilizer Trim “OFF” flag?

A

Stabilizer Trim is INOP

24
Q

What do STAB TRIM CUTOUT switches do in the cutout position?

A

Removes hydraulic power to the respective Stabilizer Trim Control Module.

25
Q

What happens if a control column input is made opposing the direction of the stabilizer trim?

A

Trim commands are interrupted.

26
Q

How are the ailerons trimmed?

A

Dual aileron trim switches on the aft pedestal. Must be pushed together to command trim changes.

27
Q

What type of trim will override the input of Electrical Trim switches on the control wheel?

A
  1. Alternate Trim Lever

2. ALTN STAB TRIM switch input

28
Q

A

2

  1. Center
  2. Right
29
Q

Ko

33
Q

ALTN STAB TRIM switches

A
  • Electrically signal Stab movement

* neutralize all other stab trim commands

34
Q

YAW DAMPER INOP

A
  • fault
  • switch off
  • IRS not aligned
35
Q

MACH

SPD TRIM

A

Mach/Speed Trim system is inoperative.

36
Q

RUDDER

RATIO

A
  1. Rudder Ratio System INOP

2. left hydraulic system pressure low

37
Q

SPEED

BRAKES

A

SPEEDBRAKES extended

<800 ft RA with Flaps in landing position

38
Q

What causes the the SPEED BRAKES light to illuminate?

A

2 conditions

  1. Flaps in the landing position with speed brakes extended
  2. RA 800 feet or below with speedbrakes extended
39
Q

SPOILERS

A

One or more spoilers pairs are inop or not in the commanded position

40
Q

STAB TRIM

A

Electric and alternate stabilizer trim is 1/2 the normal rate

Use of alternate allows

41
Q

UNSCHED

STAB TRIM

A
  1. Uncommanded stab motion detected
  2. Runaway stab motion with no pilot input
  3. Wrong way Stab moves opposite of autopilot or Mach speed trim.
  4. Use of alternate Trim with an autopilot engaged.
42
Q

AUTO SPDBRK

A

Fault detected may result in loss of AUTO SPDBRK extension

43
Q

Mach Speed Trim SYS

A

Controls stab when autopilot not engaged
• Improves speed stability
• electric, alternate or autopilot trimming overrides Mach speed trim

44
Q

Aileron trimming w/autopilot

A

Changed neutral point without showing it on the scale.
