25
Q

What do Ailerons control?

A

The Ailerons control the flight attitude of the airplane around the longitudinal axis. (Roll)

26
Q

What does the Elevator control?

A

The elevator controls the attitude of the airplane about the lateral axis. (Pitch)

27
Q

What does the Rudder control?

A

The Rudder controls the flight attitude of the airplane around the vertical axis. (Yaw)

28
Q

What is the purpose of secondary flight controls?

A

The secondary flight controls improve the lift and handling properties of the airplane

29
Q

What components are included in secondary flight controls?

A

(12) Leading Edge Devices, (4) Trailing Edge Flaps, (12) Spoilers and Speedbrakes, and the Horizontal stabilizer

30
Q

What is the purpose of Leading Edge Devices?

A

The Leading Edge (LE) Flaps and Slats increase the wing area and the wing camber. This increases lift to help improve the takeoff and landing performance of the airplane.

31
Q

What is the purpose of Trailing Edge Flaps?

A

The Trailing Edge Flaps increase the wing area and the wing camber. This increases lift to help improve the takeoff and landing performance of the airplane.

32
Q

What is the purpose of Spoilers and Speedbrakes?

A

The spoilers help the Ailerons control airplane roll about the longitudinal axis.

They also supply Speedbrakes control to reduce lift and increase drag during landing and refused takeoff

33
Q

What do flight control cables provide?

A

flight control cables provide manual input to each flight control system.

34
Q

What does the flight control pane contain?

A

The flight control panel has hydraulic control switches and caution lights for flight control systems

35
Q

Describe the function of the Stall Warning System

A

The Stall Warning System shakes the control column when the airplane gets close to a stall

36
Q

Describe the function to the Skew Detection System

A

The Skew Detection System uses the Flap/Slat Electronics Unit (FSEU) to monitor the alignment of the TE flaps via data from the flap skew sensors and the flap position transmitters.

37
Q

Describe the function of the LE AUTOSLAT System

A

if the airplane comes near a stall, the autoslat function fully extends the LE slats.

38
Q

Describe the function of the Autopilot System

A

The autopilot system is available to control and stabilize the aircraft about its three axes (roll, pitch, and yaw)

39
Q

Describe the function of the Air/Ground System

A

The air/ground system supplies air mode and ground mode signals to airplane systems, for ground operation.

40
Q

Describe the purpose of the Landing Gear and Doors

A

The Landing Gear absorb impact from landing and holds the airplane weight on the ground. The main landing gear also supply braking/parking functions. The doors close to aerodynamically seal the wheel wells during flight.

41
Q

What type of wheel assembly do the landing gear consist of

A

The P-8A Landing Gear consists of a dual wheel assembly mounted on each strut

42
Q

What hydraulic system supplies pressure to the Normal Brake System

A

Hydraulic System B is used to pressurize the Normal Brake System

43
Q

What Hydraulic System supplies pressure to the Alternate Brake System

A

Hydraulic System A supplies power to the Alternate Brake System when System B does not supply pressure.

During landing gear retraction the Alternate Brake System is used to stop wheel rotation.

44
Q

What Brake System is used to pressurize the Parking Brake System if normal and alternate pressure is not available

A

Hydraulic Accumulator Pressure is used if normal and alternate pressure is not available.

45
Q

Describe the Anti-skid System

A

The Antiskid System controls the brake system to prevent wheel skids during application.

46
Q

Describe the Landing Gear Position Indicating and Warning System

A

The Landing Gear Position indicating and warning system shows landing gear position in the flight compartment. It also warns the pilots when the landing gear is not down for a landing.

47
Q

Autopilot utilizes Flight Control Computers (FCC) A & B to send commands to aileron and elevator actuators that control _______ and _________ of the aircraft.

A

The FCCs send commands to the aileron and elevator actuators that control MOVEMENT and FLIGHT PATH of the aircraft.

48
Q

What is the purpose of the Yaw Damper System?

A

Keeps the aircraft stable around the vertical (yaw) axis

49
Q

How does the Autothrottle (A/T) system function?

A

The A/T system uses data from airplane sensors to calculate and control engine thrust, in response to mode requests from the flight crew.

50
Q

Describe the function of the Wing Thermal Anti-Icing System

A

The WTAI system uses bleed air to heat the inboard leading edge slats of the wing.

51
Q

Describe the function of the Cowl Anti-Icing System

A

Keeps ice from forming on the engine inlet cowl.

52
Q

Keeps ice from forming on the engine inlet cowl.

A

Wingtip de-ice uses electrically powered actuators to provide a pulse to the leading edge and shatter accrued ice.

53
Q

Describe the de-iceing function of the Horizontal Stabilizer

A

The Horizontal Stabilizer utilizes electronically powered devices to give a pulse to the leading edge and shatter accrued ice.

54
Q

What do Flight Compartment Windows utilize electric heat to prevent?

A

1) Ice formation on windows
2) Prevent fog on windows
3) Improve window impact strength

55
Q

What 3 Crew/Service doors are installed on the aircraft?

A

1) Foward Entry Door
2) Foward Service Door
3) Aft Egress Door

56
Q

Where are the two Emergency Exit Doors located?

A

The Emergency Exit Doors are located over each wing.

57
Q

Describe the location and operation of the Weapons Bay Doors.

A

The Weapons Bay Doors are located on the bottom of the fuselage aft of the main wheel well.

The Weapons Bay Doors are electronically controlled and hydraulically operated.

58
Q

Where is the External Power Receptacle Door located?

A

The external power receptacle door is located on the stbd fwd section of the fuselage below the first officers window.

59
Q

What is the purpose of the Forward Airstair?

A

Allow crew and personnel access on or off the aircraft without the use of ground support equipment.

60
Q

What is the purpose of the Door Warning System?
