Q

What are Flight Control Cables used for?

A

To give manual inputs to each flight control system.

22
Q

What does the Stall warning system do?

A

Shakes the control column when the airplane gets close to a stall.

23
Q

What does the Skew Detection System do?

A

Uses the Flap/Slat Electronics Unit (FSEU) to monitor the alignment of the TE flaps.

24
Q

What does the LE AUTOSLAT System do?

A

When airplane comes close to a stall, the autoslat function fully extends the LE slats to help prevent a stall.

25
Q

What is the Autopilot used for?

A

To control and stabilize the aircraft about its three axes.

26
Q

What is the purpose of the air/ground system?

A

Supplies air mode and ground mode signals to airplane systems.

27
Q

What is the purpose of the Main Landing gear and doors?

A

Absorbs landing forces and holds most of the airplane weight when the airplane is on the ground. The doors open to permit gear operation.

28
Q

What is the purpose of the Nose Landing gear and doors?

A

Absorbs landing forces and holds forward part of the airplane weight when the airplane makes a landing. The doors open to permit gear operation.

29
Q

What type of wheels does the p8 have?

A

Dual wheel assembly mounted on each strut.

30
Q

What does Normal Brakes use?

A

Hydraulic system B pressure to operate the brakes.

31
Q

What does the Alternate Brakes use?

A

Hydraulic system A pressure when Hydraulic system B does not supply pressure.

32
Q

What does the Accumulator Brakes use?

A

Hydraulic accumulator pressure to operate the brakes if normal and alternate pressure is not available.

33
Q

Describe the hydraulic brake system

A

The hydraulic brake system controls hydraulic pressure to the main landing gear brakes via Normal Brakes, Alternate Brakes, and Accumulator Brakes.

34
Q

What series wings do the P8-A utilize

A

Boeing 737-800

35
Q

What is the purpose of the LG Position Indicating and Warning System?

A

It shows landing gear position in the flight compartment. It also warns the pilots when the landing gear is not down for a landing.

36
Q

What does the tail skid do?

A

It protects the stabilizer bulkhead and fuselage structure when the main landing gear shock struts are extended and the airplane rotates during takeoff.

37
Q

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

A

Movement

Flight path

38
Q

What does the Speed Trim do?

A

When the engine thrust is high and the airspeed is low, the Speed trim function keeps the. Speed set by pilots with commands to the Horizontal Stabilizer.

39
Q

What is Mach Trim?

A

As the Speed of the airplane increases, the Nose starts to go down, this is Mach Trim.
When the airspeed is more than Mach 0.615, the Mach Trim function gives an up elevator to keep the Nose of the airplane level.

40
Q

What does the Yaw Damper System do?

A

Keeps the airplane stable around the airplane yaw (vertical) axis.

41
Q

What function does the Autothrottle (A/T) have?

A

Uses data from airplane sensors to calculate engine thrust.

42
Q

Describe the function of the Wing Thermal Anti-Icing System.

A

It prevents ice on the leading edges of the wings by using hot air from the pneumatic system to heat the three inboard leading edge slats of the Wing.

43
Q

Describe the function of the Cowl Anti-Icing System.

A

It keeps ice from forming on the engine inlet cowl and each engine has its own system.

44
Q

Describe the de-icing function of the Raked Wingtips.

A

It uses electrically powered actuators which give a pulse to the leading edge and shatter the accrued ice.

45
Q

Describe the de-icing function of the Horizontal Stabilizer.

A

It uses electrically powered actuators which gives a pulse to the leading edge and shatter the accrued ice.

46
Q

The Air data probes use electric heat to prevent what?

A

Ice

47
Q

What do Flight Compartment Windows utilize electric heat to prevent?

A
  1. Ice formation.
  2. Prevent Fog.
  3. Improve window impact strength.
48
Q

The observer windows use electric heat to provide what?

A

Defogging

49
Q

Why do the water and waste lines and drains use electric heat?

A

To prevent ice from forming.

50
Q

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

A
  1. Forward Entry Door
  2. Forward Service Door
  3. Aft Egress Door
51
Q

Where are the Emergency Exit Doors located?

A

Above each wing.
