Abstract: Methods and systems are provided for guiding or otherwise assisting energy management of an aircraft radar vectoring en route to a runway. A method involves dynamically determining an updated predicted lateral trajectory for the radar vectoring when the current aircraft status fails to satisfy a trajectory execution criterion for a previously-predicted lateral trajectory by iteratively adjusting a runway interception point defining a segment aligned with the runway until arriving at the updated predicted lateral trajectory for which a stabilization criterion for the runway can be satisfied. The method determines a target value for an energy state parameter of the aircraft at a current location on the updated predicted lateral trajectory and provides indication of a recommended action to reduce a difference between a current value for the energy state parameter and the target value.

Abstract: Methods and systems are provided for guiding or otherwise assisting energy management of an aircraft en route to a runway. A method to optimize managing energy of an aircraft in a landing trajectory when deploying landing gear, the system including evaluating an energy state for the aircraft for a set of flight trajectories including a lateral and a vertical trajectory for a flight path in an approach phase to a runway; identifying at least one energy state for the aircraft based on a set of formulated computations based on an altitude and speed of a vertical aircraft profile on the flight path in the approach phase; and assessing in an envelope region a landing gear extension to manage the excess energy at a prediction location in the flight path; and deploy the landing gear responsive to an assessed change in the aircraft energy state in route to the runway.
