由于民航飞机在飞行过程中起飞进近与着陆是最危险的两个阶段,同时也是事故多发时期,人们早已希望能够通过一定的方法再现其飞行状态,从中找出其事故原因,避免再次发生同类事故。一、飞行数据译码飞行数据译码是将记录在民航飞机飞行记录器(俗称黑匣子)中的数据运用一定的方法转为人工可以识别的工程值。目前广泛采用的一种记录器是 QAR 光盘记录器,其将哈佛双相数据流按次序录制在 QAR 光盘上,记录容量可达200h。来自飞机及其他系统的数字式信号、离散信号
As civil aircraft taking off during approach and landing are the two most dangerous stages of flight, but also the period of multiple accidents, people have long hoped to be able to reproduce its flight status by a certain method to find out the cause of the accident, to avoid recurrence of similar ACCIDENT. First, the flight data decoding Flight data decoding is recorded in the Civil Aviation Flight Recorder (commonly known as black box) data using a certain method into a manually identifiable engineering value. One of the most widely used recorders today is the QAR Compact Disc Recorder, which records Harvard’s biphasic data streams on QAR discs in order, with a recording capacity of up to 200h. Digital signals from aircraft and other systems, discrete signals
