主起压缩传感器 The Lord on compression sensor
简介 每个主起落架上的两个主起压缩传感器为空/地系统提供主起减震支柱的压缩位置信号 Each main landing gear on the two main up compression sensor is empty/to the system to provide the main up shock strut compression position signal 位置 主起压缩传感器位于主起外筒下部区域。靶标位上扭力臂的两侧，并由连杆连接到主起 的外筒 The Lord on compression sensor is located in the main the outer barrel lower area. A target on both sides of the torque arm, and the connecting rod connected to the Lord on the outer barrel 工作原理operating principle 当主起落架压缩时，靶标临近传感器 ，信号提供给PSEU When the main landing gear compression, target near sensor, signal provide PSEU PSEU探测到一个传感器失效时，传感器的状态被默认为远离靶标 PSEU detection to a sensor failure, the sensor state was the default is away from the target

维护实践 Maintenance practice
起落架安全销的安装 Landing gear safety pin installation 为防止外力将起落架解锁，飞机停放在地面时需安装起落架安全销。 In order to prevent external forces will unlock the landing gear, the plane parked in the ground need to install landing gear safety pin.

空地系统工作原理 Clearing system working principle





空/地系统为飞机系统提供空/地数据 Empty/land system for aircraft the system to provide the empty/data PSEU内的两个系统（系统1及系统2）都有各自独立的信号输入，但它们可 以通过PSEU共享信息 PSEU within the two system (system 1 and system 2) all have their own independent signal input, but they can through the PSEU sharing information 每个起落架上的两个压缩传感器输出空/地位置信号到PSEU，PSEU处理来 自压缩传感器的信号，动作空/地继电器 On each landing gear two compression sensor output empty/position signal to PSEU, PSEU processing from compression sensor signal, the movement empty/to relay
