Q

What is the function of the bobweight?

A

The bobweight is a metal plate attached to the base of the front stick, providing a heavier stick force when G-loading is increased. Helps enhance control feedback to prevent overstressing of the airframe.

Q

What is the purpose of the emergency hydraulic system?

A

To be used for emergency extension of the landing gear in three specific situations:

  • Primary hydraulic system failure
  • Engine Failure
  • Battery Bus Failure
21
Q

What is the purpose of the emergency hydraulic system?

A

To be used for emergency extension of the landing gear, main gear inboard doors, and flaps.

22
Q

What are the normal operating ranges for the hydraulic system pressure and fluid quantity?

A

Between 2880 and 3120 psi on the ESD, or FULL AC/AD in the reservoir level window.

23
Q

When is the emergency landing gear extension system used?

A
  • Primary hydraulic system failure
  • Engine Failure
  • Battery Bus Failure
24
Q

What is the normal sequence for the emergency extension of the landing gear?

A

Lower landing gear select handle, pull emergency landing gear handle.

25
Q

Can the flaps be operated in the event the primary hydraulic system fails?

A

Yes- first the emergency landing gear handle must be pulled.

26
Q

What is the purpose of the speed brake?

A

Allows deceleration and increase your descent rate without increasing airspeed.

27
Q

Where is the speed brake circuit breaker located?

A

On the generator bus.

28
Q

What can happen if NWS is engaged at high taxi speeds?

A

It can result in directional control problems due to increased sensitivity.

29
Q

Which has the larger turn radius, NWS or differential braking?

A

NWS

30
Q

What are the indications of abnormal primary flight control operations?

A

Uncommanded pitch, roll, or yaw movements.

Sluggish response to control inputs.

31
Q

What is the corrective action to take in the case of runaway trim?

A

Perform the runaway trim checklist procedure.

32
Q

If the EHYD PX LO illuminates, what aircraft devices should you consider inoperative?

A

Emergency landing gear and flap extension.

33
Q

What are some indications of unsafe landing gear?

A 
Indicator lights
Lack of noticeable drag/noise
AOA indexer not active
Inability to turn on landing or taxi lights
Tendency to roll
34
Q

What indicator lights would illuminate with the main landing gear full down, the nose gear still fully retracted, and the PCL above IDLE?

A

Two green mains, two red mains, and a red gear handle light.

35
Q

When lowering flaps using the emergency system, what two conditions might result?

A

The flaps might extend only partially, or they may take a longer time to extend than normal.

36
Q

What are the indications of wheel brake failure?

A

Inability to maintain directional control
Inability to slow down
Soft brake pedals
The aircraft pulls to one side

37
Q

A ground-adjustable trim tab is found on:

A

The ailerons

38
Q

What are the factors used by the TAD computer to calculate proper rudder trim tab settings?

A

Pitch rate
Altitude
Airspeed
Engine Torque

39
Q

Once takeoff trim is set, the TAD will make no further trim inputs until:

A

Airspeed is greater than 80 KIAS, and there is no weight-on-wheels.

40
Q

The primary and emergency hydraulic systems are pressurized to what level?

A

3000 +-120

41
Q

What is the function of the hydraulic system engine-driven pump?

A

To provide the pressure for the force of the primary hydraulic system.

42
Q

What is the function of the hydraulic system engine-driven pump?

A

To provide the hydraulic pressure for the primary hydraulic system, and also to the emergency accumulator.

43
Q

When extending the landing gear, which gear door ultimately closes as part of the extension sequence?

A

The main gear inboard doors.

44
Q

What does the red light in the landing gear sector handle indicate when illuminated?

A

Gear doors not closed

PCL is approaching IDLE with gear handle UP

45
Q

What happens to the speed brake if the hydraulic system fails?

A

It is inoperative.

46
Q

The flaps should not be operated above what airspeed?

A

150 KIAS

47
Q

When completing a sharp turn, how should NWS be used?

A

It should be turned off so that the angle of the nosewheel is not limited.

48
Q

What causes the EHYD PX LO light to come on.

A

The emergency hydraulic pressure is less than 2400 +- 150 psi.
