US Patent 9257047 Computation of new aircraft trajectory using time factor

A time factor corresponding to an airspace delay or acceleration is communicated to an aircraft. A flight management computer or other computational device of the aircraft calculates a proposed change in trajectory in order to accommodate the time factor in an optimum or nearly optimum manner. One or more proposed changes in trajectory are subject to review by the pilot or other flight personnel. An operator-selected change in trajectory is then implemented in order to accommodate a new arrival time of the aircraft at its destination or a positional point.
