介绍了基于FlightGear的近地警告系统飞行仿真测试环境搭建方法。该测试环境主要由主控系统、飞行仿真系统、视景系统以及机载设备激励系统组成。其中主控系统用于人机接口控制,视景系统用于营造真实的飞行视景环境,飞行仿真系统用于产生近地警告仿真数据源,机载设备激励系统用于仿真数据源与近地警告系统间的数据类型匹配。 Introduced FlightGear based near ground warning system flight simulation test environment to build method. The test environment mainly by the master control system, flight simulation system, visual system and airborne equipment incentive system. The main control system is used for man-machine interface control, the visual system is used to create a real flight visual environment, the flight simulation system is used to generate near-ground warning simulation data source, and the onboard equipment excitation system is used to simulate the data source and near- Warning Data type match between systems.
