早期的飞机健康管理系统像波音727和经典型波音737、DC-9和 MD-80等飞机,机械和模拟系统的测试只是按下一个按钮为内部电路提供电流,绿灯亮表示一切正常。这种按键测试是机内测试设备(BITE)的雏形。自20世纪80年代初,由电子硬件和软件组成的数字式系统被引入到波音737、757、767、MD-90和 A320飞机上。这些新的数字式系统向飞机维修人员提出了挑战,因为他们只能根据系统自身提供的指示获取信息并进行故障检测和隔离。面对这种技术挑战,诞
Early aircraft health management systems such as the Boeing 727 and the classic Boeing 737, DC-9 and MD-80 aircraft, mechanical and analog systems were tested by simply pushing a button to power the internal circuitry and a green light to indicate everything was OK. This button test is the prototype of the in-flight test equipment (BITE). Since the early 1980s, digital systems consisting of electronic hardware and software have been introduced to Boeing 737, 757, 767, MD-90 and A320 aircraft. These new digital systems challenge aircraft maintenance personnel because they can only access information and conduct fault detection and isolation based on instructions provided by the system itself. Faced with this technical challenge, Christmas
