航空记录器自出现以来的50年间,为事故/事故征候分析、故障诊断、视情维修、飞行品质监控、试飞监控等提供了丰富的信息。近年来,随着飞机系统不断改进,飞行数据记录器(FlightDataRecorder,FDR)记录的参数己由过去少量的模拟参数发展到现在大量以数字格式记录的参数,驾驶舱话音记录器(CockpitVoiceRecorder,CVR)的记录时间也由原来0.5小时延长到2小时,而且记录器的使用功能也在发生着变化。正确了解、认识和维护航空记录器,对最大限度地利用记录器记录的信息解决飞机使用和维护中出现的技术问题是十分重要的。
Over the 50 years since its inception, the Aviation Recorder has provided a wealth of information for accident / incident analysis, fault diagnosis, condition-based maintenance, flight quality control, flight monitoring and more. In recent years, with the continuous improvement of aircraft systems, the parameters recorded by Flight Data Recorder (FDR) have evolved from a few analog parameters to the current large number of parameters recorded in digital format. Cockpit Voice Recorder (CVR) The recording time is also extended from 0.5 hours to 2 hours, and the recorder’s use of features are also changing. Correct understanding, understanding and maintenance of aviation recorders is very important in resolving technical problems arising from the use and maintenance of aircraft in order to make maximum use of the information recorded by the recorders.
