  • 2. 

    The hydraulic PTU will active if :

    • A significant pressure loss occurs in any of the tree hydraulics systems.

    • A significant pressure loss occurs in the green or yellow hydraulic system.

    • Both A and B are correct.

    Correct Answer
    A. A significant pressure loss occurs in the green or yellow hydraulic system.
    Explanation
    The correct answer is that the hydraulic PTU will activate if a significant pressure loss occurs in the green or yellow hydraulic system. This means that if there is a drop in pressure in either the green or yellow hydraulic system, the PTU will automatically activate to provide backup hydraulic power. This is important because a loss of hydraulic pressure can result in a loss of control of the aircraft, so the PTU serves as a safety measure to ensure that hydraulic power is still available in case of a pressure loss in these systems.

    Rate this question:

  • 3. 

    Describes the PTU status with a green system reservoir overheat ,low pressure or low fluid level .

    • The PTU will be inhibited.

    • The crew must select the PTU ON .

    • The PTU  fault light will remain illuminated as long as the problem exists. The PTU should be selected OFF.

    Correct Answer
    A. The PTU  fault light will remain illuminated as long as the problem exists. The PTU should be selected OFF.
    Explanation
    The correct answer states that the PTU fault light will remain illuminated as long as the problem exists and that the PTU should be selected OFF. This means that when there is an issue with the PTU status, indicated by a green system reservoir overheat, low pressure, or low fluid level, the PTU will be inhibited and the crew must manually select the PTU ON. However, the fault light will continue to be illuminated until the problem is resolved, and at that point, the PTU should be turned OFF.

    Rate this question:

  • 4. 

    The PTU will self test :

    • Numerous times during each flight.

    • During the first engine start.

    • During the second engine start.

    Correct Answer
    A. During the second engine start.
    Explanation
    The PTU (Power Transfer Unit) will self-test during the second engine start. This suggests that the self-test process is not initiated during the first engine start, but rather during the subsequent start. The reason for this could be that the self-test is designed to ensure that the PTU is functioning properly after the first engine has been started and is operational. By conducting the self-test during the second engine start, any potential issues with the PTU can be identified and addressed before the aircraft takes off.

    Rate this question:

  • 5. 

    When will normal operation of the BLUE system hydraulic pump begin ?

    • During the first engine start.

    • When the first engine MASTER switch is moved to the ON position.

    • Only when the RAT is deployed.

    Correct Answer
    A. During the first engine start.
    Explanation
    The correct answer is "During the first engine start." This means that the normal operation of the BLUE system hydraulic pump will begin when the first engine is started. It does not depend on the position of the first engine MASTER switch or the deployment of the RAT (Ram Air Turbine).

    Rate this question:

    Explanation
    The yellow hydraulic system is pressurized by an engine driven pump, an electric pump, the PTU using the green system, and a hand pump for the cargo doors.

    Rate this question:

  • 9. 

    The RAT  is capable of powering a pump which will pressurize :

    • Only the blue system.

    • The blue and green system.

    • The blue and yellow system.

    Correct Answer
    A. Only the blue system.
    Explanation
    The RAT (Ram Air Turbine) is a device that generates power from the airflow during flight. It is capable of powering a pump, which can be used to pressurize a system. In this case, the question states that the RAT can pressurize "only the blue system." This means that the pump powered by the RAT is specifically designed to provide pressure to the blue system and not to any other systems such as the green or yellow system. Therefore, the correct answer is that the RAT can only pressurize the blue system.

    • Both A and B.

    Correct Answer
    A. Rain repellent and windshield wipers.
    Explanation
    Rain protection is provided by rain repellent and windshield wipers. Rain repellent is a chemical coating applied to the windshield that causes water to bead up and roll off, improving visibility in rainy conditions. Windshield wipers are mechanical devices that move back and forth across the windshield, wiping away water and debris. Both rain repellent and windshield wipers work together to ensure that the windshield remains clear and the driver's visibility is not compromised during rainy weather.

    Rate this question:

  • 18. 

    With the loss of electrical power the wing anti ice valves :

    • Fail in their current position.

    • Fail to the open position.

    • Fail to close position.

    Correct Answer
    A. Fail to close position.
    Explanation
    When there is a loss of electrical power, the wing anti ice valves are designed to fail in the closed position. This means that in the absence of power, the valves will remain in their current position, which is closed. This is important because the wing anti ice valves are responsible for preventing ice from forming on the wings of an aircraft. By failing to close, the valves ensure that the anti ice system remains operational even in the event of a power failure, thereby preventing ice accumulation and ensuring the safety of the aircraft.

    Rate this question:

  • 19. 

    With the loss of electrical power the engine anti ice valves :

    • Fail in their current position.

    • Fail to the open position.

    • Fail to the close position.

    Correct Answer
    A. Fail to the open position.
    Explanation
    When there is a loss of electrical power, the engine anti-ice valves fail to the open position. This means that the valves, which are responsible for preventing ice formation on the engine, are unable to close. As a result, they remain open, allowing the flow of hot air to continue and prevent ice from forming on the engine. This is important for the safety and performance of the aircraft, as ice accumulation can disrupt the engine's operation.

    Rate this question:

  • 20. 

    Can the wing anti ice be tested on the ground ?

    • No.

    • Yes, valves only open for 30 seconds.

    Landing gear operation is inhibit at speed :

    • Below 100 knots.

    • Above 260

    • Below 100 knots and above 260 Knots.

    Correct Answer
    A. Above 260
    Explanation
    The correct answer is "Above 260". This means that the landing gear operation is inhibited or disabled when the aircraft's speed exceeds 260 knots. This could be due to safety reasons, as the landing gear may not be designed to handle high speeds and could cause damage or instability if deployed at such velocities. Therefore, the system is programmed to prevent the landing gear from being activated when the speed is above 260 knots.

    Rate this question:

    • No.

    • Only if the A/SKID AND N/W STRG switch is selected ON.

    • Limited nose wheel steering is available only through the captain's rudder pedals.

    Correct Answer
    A. No.
    Explanation
    When the landing gear is gravity extended, nose wheel steering will not be available unless the A/SKID AND N/W STRG switch is selected ON. Even then, the nose wheel steering will be limited and can only be controlled through the captain's rudder pedals.

    Rate this question:

  • 27. 

    Can normal landing gear operation be restored after a gravity extension if green hydraulic pressure available ?

    • Restoration is always possible .

    • It may be possible if the gravity extension was not caused by a failure of the landing gear mechanism.

    • No , only maintenance can restore normal operation.

    Correct Answer
    A. It may be possible if the gravity extension was not caused by a failure of the landing gear mechanism.
    Explanation
    If the gravity extension of the landing gear was not caused by a failure of the mechanism, then it may be possible to restore normal landing gear operation. This suggests that if the gravity extension was due to some other reason, such as a temporary loss of power or a manual release, then the landing gear can be restored to its normal operation. However, if the gravity extension was caused by a failure of the landing gear mechanism itself, then normal operation cannot be restored without maintenance.

    Rate this question:

  • 28. 

    If the Landing Gear was gravity extended using the hand crank on the center pedestal , what other systems will be inoperative ?

    • Nose wheel steering .

    • Anti skid and auto braking .

    • Nose wheel steering and anti skid .

    • Option 4

    Correct Answer
    A. Nose wheel steering .
    Explanation
    If the landing gear was gravity extended using the hand crank on the center pedestal, the nose wheel steering system will be inoperative. This is because when the landing gear is extended manually, there is no hydraulic pressure available to operate the nose wheel steering mechanism. The nose wheel steering system relies on hydraulic power to turn the nose wheel, so without it, the steering functionality will not work.

    Auto brakes , if selected , will only be activated by :

    • The struts being compressed.

    • The brake pedals being depressed.

    • The ground spoiler extension command.

    Correct Answer
    A. The ground spoiler extension command.
    Explanation
    Auto brakes are a feature in some aircraft that automatically apply the brakes when certain conditions are met. In this case, the correct answer is the ground spoiler extension command. When the ground spoiler, which is a device on the wings that disrupts the airflow and creates drag, is extended, it signals the auto brakes to activate. This allows the auto brakes to engage and assist in slowing down the aircraft during landing. The other options, such as the struts being compressed or the brake pedals being depressed, are not the correct triggers for the auto brakes.
