How aircraft know position of landing gears

Proximity sensors are vital part for aircraft systems, specialy for indication, because proxi sensors are resposnible for telling aircraft systems position of components. Description: The proximity sensor is an electronic position indicator. The main components of the sensor are a sensor body, a sensor coil and an electrical connector. The sensor has a related target. The sensor body contains the sensor coil. The coil is connected to the electrical connector. Each proximity detection circuit contains: a proximity sensor a sensor target a channel of a proximity-sensor electronics card. The proximity-sensor electronics-card has 14 channels and is located in the LGCIU. Operation The proximity sensor continuously transmits an electrical signal to the proximity-sensor electronics-card. As the target moves into or out of the proximity-sensor's actuation area it causes a change in the proximity sensor's electrical property. The electrical signal to the proximity sensor electronics card also changes. The proximity-sensor electronics-card converts these electrical signal changes into user status signals. The LGCIU control logic modules use these user status signals to control the extension and retraction of the L/G. In today's video we will take look how to replace it. ********video is just for information purposes always stick to the latest maintenance manual.******** if you want support me click here:    / @zeto.r   Where you can find me: Instagram:   / zeto.r   tiktok:   / zeto.r   Patreon: https://www.patreon.com/Zetomaintenan...
