    • A

    • B

    • Stb system

    • A and B

    Correct Answer
    A. B
    Explanation
    The correct answer is B because the question asks about the hydraulic system that operates the leading edge devices. Since the answer options include only A, B, Stb system, and A and B, and B is the only option that mentions a hydraulic system, it can be inferred that the leading edge devices are normally operated by the hydraulic system mentioned in option B.

    What is the maximum altitude for flap section?

    • 10 000 ft

    • 20 000 ft

    • 30 000 ft

    • 18 000 ft

    Correct Answer
    A. 20 000 ft
    Explanation
    The maximum altitude for the flap section is 20,000 ft. This means that the flaps on an aircraft can be extended up to 20,000 ft above ground level. Flaps are aerodynamic surfaces on the wings that can be extended or retracted to change the shape and lift characteristics of the wing. They are typically used during takeoff and landing to increase lift and reduce the aircraft's speed. The maximum altitude for the flap section indicates the highest altitude at which the flaps can still be effectively used.

    During an RTO with main gear wheel speed more than 60kts, the spoilers will automatically deploy when the thrust levers are at what position?

    • Idle and reverser is selected

    • At Full stop position

    • Idle trust

    • Max 20 % N1

    Correct Answer
    A. Idle and reverser is selected
    Explanation
    When an RTO (Rejected Takeoff) is performed with main gear wheel speed exceeding 60 knots, the spoilers will automatically deploy when the thrust levers are at the Idle position and the reverser is selected. This means that when the pilot reduces the thrust to idle and selects the reverser, the spoilers will deploy automatically to assist in decelerating the aircraft and enhancing braking effectiveness.
