METHOD AND SYSTEM FOR RECOVERING THE ENERGY STATE OF AN AIRCRAFT DURING DESCENT

摘要

A method and system is provided for the recovery of an aircraft energy upset in a time-constrained descent. The system includes a computational unit to assess a number of adjustments involving a combination of speed changes, aerodynamic brake deployment and track miles adjustments that alter the energy dissipation profile whilst allowing the aircraft to maintain a pre-determined time-of-arrival over an incoming waypoint along the original descent path.

1. A method for determining an energy recovery profile for an aircraft needed to arrive at a point along a flight path further ahead of the aircraft at as close to a desired time of arrival and energy level of a flight plan as possible, the method including:
monitoring and assessing an energy state of the aircraft and any time deviation with respect to the flight plan prior to start of descent phase of the flight plan and throughout the descent phase of a flight; comparing the current energy state to the expected energy state; identifying a trajectory and corresponding aircraft states that allows the aircraft to arrive at the point in space ahead of the aircraft at a speed, altitude and time as close to the flight plan as possible; generating adjustments to the flight plan to produce an energy recovery profile pertaining to the identified trajectory and aircraft states; and outputting the energy recovery profile to at least one of a display device and a flight management system of the aircraft.
