LGECU provides data that is used to generate alerts and synoptic displays for the fuselage doors.
Door position information is displayed on the STAT page and message information is displayed on
the PRIMARY page.
The STAT page presents the following doors:

Passenger Door
The passenger door is monitored by three proximity sensors to determine the locked and handle
stowed position. Proximity sensors (one at each location) are located on the passenger door
forward and aft latch to monitor the “G” latch position. A proximity sensor is mounted in the
passenger door to monitor the outer handle stowed condition.
The sensor information is used by the Landing Gear Electronic Control Unit (LGECU) for door
position and locked indication and sends the results to EICAS for position and locked displays.
Emergency Exit
One proximity sensor is installed at the top of the door position and senses the door in the closed
position.
