    Which of the following statements is always true when operating in alternate law ?

    • Extending the landing gear will place the aircraft in mechanical back up law

    • Extending the landing gear will place the aircraft in direct law

    • Extending the landing Gear will have not effect on the status of the flight controls 

    Correct Answer
    A. Extending the landing gear will place the aircraft in direct law
    Explanation
    When operating in alternate law, extending the landing gear will place the aircraft in direct law. Alternate law is a mode in aircraft fly-by-wire systems where certain flight control protections are lost, and the system reverts to a simpler mode of operation. In direct law, the flight controls are directly linked to the pilot's inputs without any additional protections or assistance from the flight control system. Therefore, extending the landing gear in this mode will trigger the transition to direct law.

    When in alternate law , all protections except ,,,,,,,,,,,,,,,,,,,,,, protection will be lost 

    • Pitch attitude

    • Bank angle

    • Load factor

    Correct Answer
    A. Load factor
    Explanation
    When in alternate law, all protections except load factor protection will be lost. This means that the aircraft will no longer have the automatic systems to protect it from exceeding certain load factors, which are forces acting on the aircraft in various directions. Load factor protection is important because exceeding certain load factors can lead to structural damage or even failure of the aircraft. Therefore, when in alternate law, pilots must manually monitor and control the load factor to ensure the safety of the aircraft.
