  • 2. 

    If one bleed air fails,______________the cross bleed valve to use the opposite bleed for both wings anti-ice.

    • The anti-ice system automatically opens

    • The pilot must manualy open

    Correct Answer
    A. The anti-ice system automatically opens
    Explanation
    If one bleed air fails, the anti-ice system automatically opens. This means that if one of the bleed air sources fails, the anti-ice system will automatically activate and open to allow the opposite bleed air source to be used for both wings' anti-ice. This ensures that both wings are still protected from ice buildup, even if one bleed air source is not functioning properly.

    The MCDU setting operates the anti-ice system and inhibits the ice detectors activation logic during takeoff until ________________, whichever occur first. The settings actuate as described below: 

    • 1500 ft AGL or 1 min after liftoff

    • 1700 ft AGL or 2 min after liftoff

    • 2000 ft AGL or 5 min after liftoff

    Correct Answer
    A. 1700 ft AGL or 2 min after liftoff
    Explanation
    The MCDU setting operates the anti-ice system and inhibits the ice detectors activation logic during takeoff until 1700 ft AGL or 2 min after liftoff, whichever occurs first. This means that once the aircraft reaches an altitude of 1700 ft AGL or 2 minutes after liftoff, the ice detectors will be activated and the anti-ice system will be operational. This setting ensures that the anti-ice system is not activated prematurely during takeoff, but is activated at a safe altitude or time after liftoff to prevent ice buildup on the aircraft.
