仪表着陆系统飞行校验周期延长研究

仪表着陆系统是飞机进近着陆的关键设备，其信号质量直接影响民航安全运行水平， 为确保其持续正常，按照民航规章，每 6 个月要对其进行一次定期飞行校验，随着设备数量的持续增加，给校验运力和航班支持率带来了极大困难。另一方面，设备运行单位外场信号测试手段不断丰富，有效地补充了对仪表着陆系统空间导航信号的日常监测。因此中国民航可进行试点尝试，根据设备运行状况合理设置校验周期，成熟后开始推广应用。

Research of Instrument Landing System Flight Check Period Extending

Instrument landing system is the key equipment for aircraft approach and landing, and its signal quality directly affects the safe operation level of civil aviation. In order to ensure its continuous normal operation, it shall be subject to regular flight verification every six months according to civil aviation regulations. With the continuous increase of the number of equipment, it has brought great difficulties to verify the transportation capacity and flight support rate. On the other hand, the field signal test means of the equipment operation unit are constantly enriched, which effectively complements the daily monitoring of the space navigation signal of the instrument landing system. Therefore, CAAC can make a pilot attempt, reasonably set the calibration cycle according to the equipment operation status, and start to promote the application when it is mature
