    • The instant invention provides a system and method for controlling the flight of an aircraft to meet an RTA. The system comprises a speed profile generator that communicates with a trajectory generator to produce a speed profile signal that enables the aircraft to reach a waypoint substantially at a predetermined time. In the system of the instant invention, the speed profile generator receives a nominal speed command signal, a time error signal and a sensitivity signal. Based on these inputs, the speed profile generator produces a speed profile signal. The trajectory generator receives the speed profile signal and a required time of arrival signal. Based on these signals, the trajectory generator produces a time error signal and a sensitivity signal. This sensitivity signal represents the sensitivity of the time error signal to changes in the speed profile signal.
    • 本发明提供了一种用于控制飞行器满足RTA的飞行的系统和方法。 该系统包括与轨迹发生器通信以产生速度分布信号的速度曲线发生器,该速度曲线信号使飞机能够在预定时间内达到航点。 在本发明的系统中,速度曲线发生器接收标称速度指令信号,时间误差信号和灵敏度信号。 基于这些输入,速度曲线生成器产生速度曲线信号。 轨迹发生器接收速度曲线信号和所需的到达时间信号。 基于这些信号,轨迹发生器产生时间误差信号和灵敏度信号。 该灵敏度信号表示时间误差信号对速度分布信号变化的灵敏度。
