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.
