(12) Leading Edge Devices, (4) Trailing Edge Flaps, (12) Spoilers and Speedbrakes, and the Horizontal stabilizer
What is the purpose of Leading Edge Devices
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.
What is the purpose of Trailing Edge Flaps
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.
What is the purpose of Spoilers and Speedbrakes
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
What do flight control cables provide
flight control cables provide manual input to each flight control system.
What is the purpose of the flight control panel
The flight control panel has hydraulic control switches and caution lights for flight control systems
Describe the function of the Stall Warning System
The Stall Warning System shakes the control column when the airplane gets close to a stall
Describe the function to the Skew Detection System
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.
Describe the function of the LE AUTOSLAT System
if the airplane comes near a stall, the autoslat function fully extends the LE slats.
Describe the function of the Autopilot System
The autopilot system is available to control and stabilize the aircraft about its three axes (roll, pitch, and yaw)
Refer to attached image for flight control Illustration
Describe the function of the Air/Ground System
The air/ground system supplies air mode and ground mode signals to airplane systems, for ground operation.
Describe the purpose of the Landing Gear and Doors
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.
What type of wheel assembly do the landing gear consist of
The P-8A Landing Gear consists of a dual wheel assembly mounted on each strut
Describe the Hydraulic Brake System
The hydraulic brake system controls hydraulic pressure to the main landing gear brakes via Normal Brakes, Alternate Brakes, and Accumulator Brakes.
What hydraulic system supplies pressure to the Normal Brake System
Hydraulic System B is used to pressurize the Normal Brake System
What Hydraulic System supplies pressure to the Alternate Brake System
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.
What Brake System is used to pressurize the Parking Brake System if normal and alternate pressure is not available
Hydraulic Accumulator Pressure is used if normal and alternate pressure is not available.
Describe the Antiskid System
The Antiskid System controls the brake system to prevent wheel skids during application.
Describe the Landing Gear Position Indicating and Warning System
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.
Autopilot utilizes Flight Control Computers (FCC) A & B to send commands to aileron and elevator actuators that control _______ and _________ of the aircraft.
The FCCs send commands to the aileron and elevator actuators that control MOVEMENT and FLIGHT PATH of the aircraft.
What is the purpose of the Yaw Damper System?
Keeps the aircraft stable around the vertical (yaw) axis
How does the Autothrottle (A/T) system function?
The A/T system uses data from airplane sensors to calculate and control engine thrust, in response to mode requests from the flight crew.
Describe the function of the Wing Thermal Anti-Icing System

Describe the function of the Cowl Anti-Icing System
Keeps ice from forming on the engine inlet cowl.
Describe the de-iceing function of the Raked Wing Tip
Wingtip de-ice uses electrically powered actuators to provide a pulse to the leading edge and shatter accrued ice.
Describe the de-iceing function of the Horizontal Stabilizer
The Horizontal Stabilizer utilizes electronically powered devices to give a pulse to the leading edge and shatter accrued ice.
