    • C.

      Not inhibited

    • D.

      1500ft to lift off

    Correct Answer
    B. 80 kts to 1500 ft
    Explanation
    During take-off, the avionic smoke warning is inhibited from 80 knots (kts) to 1500 feet. This means that if there is any smoke detected in the avionics system during this period, the warning system will not activate. Once the aircraft reaches a speed of 80 kts during take-off, the smoke warning system is disabled until it reaches an altitude of 1500 feet. This is done to prevent false alarms or distractions during the critical phase of take-off.

    • C.

      ECAM, CIDS and Nose interphone panel

    • D.

      Nose interphone panel

    Correct Answer
    B. ECAM and CIDS
    Explanation
    Lavatory smoke detectors send warnings to ECAM (Electronic Centralized Aircraft Monitoring) and CIDS (Cabin Intercommunication Data System). ECAM is responsible for monitoring and displaying various aircraft systems, including smoke detection. CIDS is a communication system that allows crew members to communicate with each other and receive important information. Therefore, both ECAM and CIDS receive warnings from lavatory smoke detectors to ensure prompt action can be taken in case of a fire or smoke in the lavatory.

    In case of cargo compartment smoke warning, the agent bottle if discharged should be empty in less than

    • A.

      10 seconds

    • B.

      3 minutes

    • C.

      1 minute

    • D.

      30 seconds

    Correct Answer
    C. 1 minute
    Explanation
    The correct answer is 1 minute because in case of a cargo compartment smoke warning, it is crucial for the agent bottle to be discharged quickly in order to suppress the fire and prevent further damage. A discharge time of 1 minute ensures that the agent is released rapidly enough to effectively combat the smoke and fire in the cargo compartment. A longer discharge time could result in the fire spreading and causing more harm, while a shorter discharge time may not provide sufficient agent to extinguish the fire completely.
