Methods and system for time of arrival control using time of arrival uncertainty

摘要

Methods and a system for vehicle control are provided. The system includes an input device configured to receive a required time of arrival at a waypoint and a processor communicatively coupled to the input device. The processor is programmed to determine a forward late time profile, determine a forward early time profile representing the earliest time the vehicle could arrive at a point along the track and still arrive at the waypoint while transiting at a maximum available speed, and determine an estimated time uncertainty (ETU) associated with at least one of the forward late time profile and the forward early time profile. The system also includes an output device communicatively coupled to the processor, the output device configured to transmit the determined uncertainty with a respective one of the at least one of the forward late time profile and the forward early time profile to a display.
