随着航空电子技术的发展与应用,现代飞机大量采用高新技术,自动化和数字化程度越来越高,计算机软件的使用越来越广泛,飞机电子系统发生了很大的变化。现代飞机中有大量的机载电子设备都需要专用的软件支持才能正常工作。按飞机维修手册(AMM)手册规定在更换这些相应组件时,必须检查其内部所安装的软件是否有效,若不是有效的则需进行软件安装。可由软件来修改的飞机系统在波音飞机中已成为一种标准。这种特性允许通过更新软件来改变此系统的构型,而不用进行物理改装或更换硬件。
With the development and application of avionics technology, modern aircraft use a lot of high and new technology, the degree of automation and digitization is getting higher and higher, the use of computer software is more and more widespread, and the aircraft electronic system has undergone great changes. Modern aircraft have a large number of airborne electronic devices require special software support to work properly. According to the Manual of Aircraft Maintenance Manual (AMM), when replacing these corresponding components, it is necessary to check whether the software installed inside them is valid or not, if not, the software installation is required. Aircraft systems that can be modified by software have become a standard in Boeing aircraft. This feature allows the configuration of this system to be changed by updating the software without physically modifying or replacing the hardware.
