Embodiment
[0085] The testability of the software of two display control management systems (DCMS) and two mission computer systems (MCS) was measured by using the method provided by the invention. DCMS and MCS are two important subsystems of the avionics system. Among them, DCMS is responsible for receiving and displaying data from other subsystems, and controlling other subsystems according to pilot instructions; MCS calculates aircraft attitude based on sensor data, and performs functions such as flight management and fire control calculation. Most of the functions of the four systems are implemented by embedded software, which are respectively recorded as DCMS α 、DCMS β 、MCS α and MCS β , where version β is an upgraded version of version α. DCMS is detailed belowα The testability measurement process:
