现代航空器均配备有固定式ELT系统及便携式ELT,由于固定式ELT系统时刻处于待命状态,以便在飞机出现紧急情况时,及时发射救援信号。但是飞机出现重着陆以及机组和维修人员的不当操作也会触发ELT系统发射应急救援信号,此时就需要及时通过RCP或ELT发射机上的开关对系统进行复位,以终止误发射,防止对应急救援频道的干扰。鉴于ELT系统的特殊性及重要性,民航局对其维护和测试有着严格规定。文章就近期一起航空器固定式ELT系统误警告的处理过程进行描述和分析。
Modern aircraft are equipped with a fixed ELT system and a portable ELT. Since the fixed ELT system is on standby at all times, rescue signals can be transmitted in time when an aircraft is in an emergency. However, a heavy landing of the aircraft and improper operation of the crew and maintenance personnel will also trigger the ELT system to launch an emergency rescue signal. In this case, the system needs to be reset by means of a switch on the RCP or ELT transmitter in time to stop the erroneous launch and prevent emergency rescue Channel interference. In view of the particularity and importance of the ELT system, CAAC has strict rules on its maintenance and testing. The article describes and analyzes the recent treatment of erroneous warnings on stationary ELT systems.
