1. A method for an aircraft having a flight management system (FMS), the method comprising:

  • receiving at least one assigned time factor from a ground based entity as the aircraft is flying towards a destination, the at least one assigned time factor imposing an arrival constraint at the destination;

    using the FMS to compute a plurality of new trajectories from a current location of the aircraft to the destination, the new trajectories computed in accordance with corresponding new time factors that satisfy the arrival constraint; and

    selecting one of the new trajectories based on flight and customer parameters and performance characteristics of the aircraft.
