鉴于飞行数据记录器在保障飞行安全中的重要地位,前苏联民航飞机早在20多年前就开始广泛使用了这类装置。与国际通行惯例类似,目前独联体民航飞机也同时装有两台飞行数据记录器。一种是备有特殊防护能力、装在飞机最安全部位的装置,用于飞机失事时帮助事故调查人员分析和查明失事原因。该装置平时是不可拆卸的。另一种飞行数据记录器是飞行后可拆卸的,用于监督飞行及监控飞机各系统的性能状况,为飞机及系统维修人员提供有关参数。
Given the importance of flight data recorders in ensuring flight safety, the former Soviet Union civil aircraft began to make extensive use of such devices more than two decades ago. Similar to common international practice, the current Commonwealth Civil Aviation aircraft is also equipped with two flight data recorders. One is equipped with special protection capabilities, installed in the safest part of the aircraft equipment, to help accident investigators to analyze and identify the cause of the crash when the plane crashed. The device is usually not removable. Another type of flight data recorder, which is detachable after flight, is used to supervise the flight and monitor the performance of each system of the aircraft, providing relevant parameters for aircraft and system maintenance personnel.
