    Study Notes

    Door Actuator

    • The door actuator on Boeing Aircraft is a double acting hydraulic cylinder, known as the wheel well door actuator.
    • It is responsible for moving the doors on aircraft, particularly the wheel well doors.
    • Proximity sensors are installed on the door to provide feedback on their position, indicating whether they are open or closed.
    • This feedback is crucial for the sequencing of gear extension and retraction.

    Position Feedback and Safety

    • The signals from the proximity sensors are used to determine the door position.
    • This information is critical for ensuring the correct sequence of actions during gear extension and retraction, contributing to safety and operational efficiency.
