    Explanation
    The F-22 pitch system is augmented by thrust vector nozzles. These nozzles are designed to redirect the exhaust gases from the engines, allowing the aircraft to change its pitch or angle of attack. By manipulating the direction of the exhaust, the thrust vector nozzles provide additional control and maneuverability to the F-22, enabling it to perform complex aerial maneuvers and maintain stability in flight.

    The landing gear handle controls flap setting when norm is selected on the F-22s

    • A.

      Reset switch

    • B.

      Auto pitch rock switch

    • C.

      Flap alt switch

    • D.

      Built-in switch

    Correct Answer
    C. Flap alt switch
    Explanation
    The correct answer is flap alt switch. The explanation for this is that the flap alt switch on the F-22s controls the flap setting when the norm mode is selected. This switch allows the pilot to adjust the position of the flaps based on the altitude of the aircraft. It is a built-in switch specifically designed for this purpose, and it ensures that the flaps are set correctly for optimal performance during different flight conditions.

    F-22 lift augmentation is performed by

    • A.

      Vectorin thrust

    • B.

      Vectoring thrust

    • C.

      Leading edge flaps

    • D.

      Large stabilators

    Correct Answer
    C. Leading edge flaps
    Explanation
    Lift augmentation in the F-22 is achieved through the use of leading edge flaps. These flaps are located on the leading edge of the wings and can be extended or retracted as needed to modify the airflow over the wings. By extending the leading edge flaps, the curvature of the wing is increased, resulting in increased lift. This allows the F-22 to generate more lift at lower speeds, improving its maneuverability and performance during takeoff and landing. Vectoring thrust refers to the ability of the engines to direct their exhaust gases in different directions, which is not directly related to lift augmentation. Large stabilators are control surfaces on the tail of the aircraft and do not directly contribute to lift augmentation.

    The F-22 leading edge flap position is based on AOA, Mach and altitude information computed by the

    • A.

      Flight control system

    • B.

      Vehicle management system

    • C.

      Stability augmentation system

    • D.

      Flight management control system

    Correct Answer
    B. Vehicle management system
    Explanation
    The correct answer is the Vehicle management system. The Vehicle management system is responsible for computing and providing information about the aircraft's AOA (Angle of Attack), Mach number, and altitude. Based on this information, the F-22 leading edge flap position is determined. The Vehicle management system is an integral part of the aircraft's flight control system and is responsible for managing various aircraft systems, including the control surfaces.

    ON the F-22, which valve allows aerioal refuel flow to the aircraft plumbing and prevents flow in the reverse direction?

    • A.

      Check

    • B.

      Relief

    • C.

      Bypass

    • D.

      Control

    Correct Answer
    A. Check
    Explanation
    The valve that allows aerial refuel flow to the aircraft plumbing and prevents flow in the reverse direction is called the check valve. This valve ensures that fuel can flow into the aircraft during aerial refueling but prevents any backflow or reverse flow of fuel.
