A projected recovery trajectory (60) for an aircraft autopilot system is precomputed by providing a stored set of predefined recovery mode segments, including: a mode 1 segment that models the aircraft coasting; a mode 2 segment that models the aircraft executing a nose high recovery; a mode 3 segment that models the aircraft executing a nose low recovery; a mode 4 segment that models the aircraft executing a throttle only recovery; and a mode 5 segment that models the aircraft executing a terrain avoidance recovery. A processor generates at least one projected recovery trajectory (60) based on a current state of the aircraft, where the processor selectively concatenates selected ones of the predefined recovery mode segments (100) into a sequence and uses that sequence to generate the projected trajectory (60).
通过提供存储的一组预定义恢复模式片段来预先计算飞行器自动驾驶系统的规划恢复轨迹(60),该组恢复模式片段包括:模式1片段,用于对飞行器滑行进行建模;模式2片段,用于对飞行器执行机头高恢复进行建模;模式3片段,用于对飞行器执行机头低恢复进行建模;模式4片段,用于对飞行器执行仅油门恢复进行建模;以及模式5片段,用于对飞行器执行地形规避恢复进行建模。处理器基于飞行器的当前状态生成至少一个规划恢复轨迹(60),其中处理器将预定义恢复模式片段(100)中的选定片段选择性地级联为序列,并使用该序列来生成所述规划轨迹(60)。
