Abstract: A method for computing a required speed profile for an aircraft to meet a required time of arrival (RTA) for a waypoint of a current flight is provided. During flight, the method calculates a fuel-efficient speed profile for the aircraft to meet the RTA for the waypoint, by a processor of a computing device communicatively coupled to one or more avionics systems onboard the aircraft; activates the fuel-efficient speed profile to fly the aircraft to the waypoint, by the processor; determines a priority between fuel efficiency of the fuel-efficient speed profile and time reliability, by the processor; and when the priority is the time reliability, switches from the fuel-efficient speed profile to a guidance margin control strategy to fly the aircraft to the waypoint, wherein the guidance margin control strategy increases the time reliability by enabling the aircraft to satisfy constraints of the RTA.

Abstract: A method is provided for controlling speed of a vehicle. The method includes determining an arrival time error (ATE) for a required time of arrival (RTA) and a projected trajectory according to a travel plan with a current speed profile having a plurality of regions, each with a respective speed adjustment parameter (SAP) and a respective SAP value relative to a nominal speed profile. The method further includes selecting, when the ATE is greater than a threshold, one of the regions as a selected region for modification based on a priority order of the regions. The method further includes modifying the current speed profile by adjusting the respective SAP value for the selected region according to the respective SAP in order to decrease the ATE; and implementing the modified speed profile.
