METHOD AND SYSTEM FOR VERTICAL NAVIGATION USING TIME-OF-ARRIVAL CONTROL

摘要

A control system (100) for controlling a speed of a vehicle is provided. The system (100) includes an input device (114) configured to receive a required time of arrival (RTA) at a waypoint, a processor (104) communicatively coupled to the input device, the processor programmed to automatically determine a dynamically adjustable range for an autothrottle control using an RTA error and an RTA tolerance, the RTA error representing a difference between an estimated time of arrival (ETA) and the RTA, the speed control tolerance representing a time accuracy requirement about the specified RTA, and an output device communicatively coupled to the processor, the output device is configured to transmit at least one of a thrust control signal and a drag control signal to a speed control system of the vehicle.
