飞机外场检测用的自动测试系统最早出现在五十年代初期。当时主要用于军用电子设备的检测。提出使用自动测试系统的主要原因是由于机载武器系统越来越复杂,为确保飞机的飞行安全和武器投放的准确性,才研制出自动测试系统。美国是首先研制和使用自动测试系统的国家。该系统具有模拟和数字显示能力,可对雷达、惯导设备,大气数椐计算机和自动驾驶仪等一系列航空电子设备进行外场检 The automatic test system for aircraft field detection first appeared in the early 1950s. At that time mainly for the detection of military electronic equipment. The main reason for using the automatic test system is that the automatic test system has been developed to ensure the flight safety of the aircraft and the accuracy of the weapon deployment due to the complexity of the airborne weapon system. The United States is the first country to develop and use automated test systems. The system has analogue and digital display capabilities for field detection of a wide range of avionics such as radar, inertial navigation equipment, computers and autopilots
