Q

What are Ailerons used for?

A

Used in pairs to control aircraft in roll, or movement around longitudinal axis.

24
Q

What is “rolling” or “banking”?

A

Shift in horizontal stabilizer, resulting in change of heading.

25
Q

Leading Edge Flap (LEF) control subsystem receives input from what device?

A

Vehicle Management Computer (VMC)

26
Q

The Vehicle Management Computer (VMC) consists of what components?

A
  • Left Hand Electronic Unit

- Right Hand Electronic Unit

27
Q

What is the functions of the Left Hand and Right Hand Electronic Units?

A

Controls and operates 2 wing Power Drive Units (PDUs) and supplies the Vehicle Management Computer (VMC) with management, Built-in Test (BIT), and health monitoring data.

28
Q

What are flaps?

A

Hinged surfaces mounted on trailing edges of wings.

29
Q

What are flaps used for?

A
  • Reduce speed so aircraft can be safely flown and increase angle of descent for landing
    (Shorten takeoff and landing distances)
30
Q

What is a rudder?

A

Control surface, typically controlled by pedals.

31
Q

What is a rudder used for?

A

Controls yaw (rotation of aircraft about vertical axis)

32
Q

Where is the spoiler located?

A

Along leading edge flap.

33
Q

What is the spoiler used for?

A

Extends into air stream creating drag and slowing airspeed.

34
Q

What components make up the landing gear subsystem?

A
  • Main and nose landing gear extension/retraction
  • Wheel and brakes
  • Nose wheel steering
  • Position and warning
  • Arresting gear
35
Q

What does the Nose Landing Gear (NLG) strut assembly provide?

A

36
Q

Where is the Nose Landing Gear (NLG) located?

A

Underside of forward fuselage.

37
Q

Where is the launch bar located?

A

Forward side of NLG shock strut.

38
Q

What is the purpose of the launch bar?

A

Engages catapult, applying catapult tow forces to aircraft for launch.

39
Q

What does the Nose Wheel Steering (NWS) provide?

A

Assists in giving aircraft directional control during taxiing and take-off procedure.

40
Q

What device/component is used to control the nose wheel steering?

A

Rudder pedals located in cockpit.

41
