Claim Text:
1. A method for determining a feasible required time of arrival comprising: receiving an initial required time of arrival; determining one or more flight constraints based on at least one of a current aircraft state, one or more aircraft performance limitations and one or more environmental conditions; determining a maximum airspeed achievable by an aircraft based on the one or more flight constraints; determining a minimum airspeed achievable by the aircraft based on the one or more flight constraints; determining that the initial required time of arrival is not feasible based on the one or more flight constraints, producing an earliest time of arrival representing the earliest possible time the aircraft can reach a metering waypoint while complying with the one or more flight constraints; producing a latest time of arrival representing the latest possible time the aircraft can reach a metering waypoint while complying with the one or more flight constraints; and communicating the earliest time of arrival and latest time of arrival to an air traffic controller, wherein:
