A four dimensional time controlled flight management system (4DFMS) and related method generate an initial descent profile for an aircraft in flight. The initial descent profile is planned in compliance with a 1) a published arrival procedure at an airport, 2) a fuel-efficient optimized profile descent (OPD), and a required time of arrival (RTA) constraint at a metering waypoint on the published arrival. The 4DFMS maintains awareness of the changing wind conditions during cruise mode and descent mode of operation and triggers a replan of the descent profile should compliance fall outside of a 95% confidence level at a six second compliance requirement in the descent mode. The system continuously generates a total time error at the metering waypoint by projecting estimated time of arrivals at active waypoints to determine accurate altitude, airspeed, and time compliance at the metering waypoint.
