Embodiment Construction

[0040] Exemplary embodiments of systems and methods for planning and flying a cost-optimal cruise vertical profile in combination with RTA constraints are described in detail below. However, not all features of an actual implementation are described in this specification. Those skilled in the art will understand that in the development of any such actual implementation, many implementation-specific decisions must be made to achieve the developer's specific goals (e.g., compliance with system-related and business-related constraints that will vary from one implementation to another). In addition, it will be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

Abstract

The present invention relates to a system and method for optimizing a cruise vertical profile subject to time-of-arrival constraint, and a system and method for planning and flying a cost-optimal cruise vertical profile in combination with a required time-of-arrival (RTA) constraint. The method may be implemented as a single function in a flight management system (FMS). The FMS (10) plans the aircraft trajectory with cruise vertical and speed profiles that are optimized to minimize flight cost (e.g., fuel burn) while meeting the time constraint. On appropriate conditions, the integrated function is also able to degrade the cruise vertical profile in order to open the window of achievable RTAs and increase the RTA success rate. The method also monitors progress of the flight along the planned trajectory as actual flight conditions may differ from the forecasted flight conditions, and readapts the cruise speed profile when the estimated arrival time is deviating from the RTA constraint by more than a specified threshold.

Description

technical field [0001] The present disclosure generally relates to systems and methods for optimizing a cruise profile of an aircraft. The cruise profile of the aircraft includes a cruise speed profile indicative of a change in speed along the planned flight path during the cruise phase and a cruise vertical profile indicative of an altitude change along the planned flight path during the cruise phase . In particular, the present disclosure relates to systems and methods for optimizing the cruise vertical profile of an aircraft. Background technique [0002] As used herein, the term "aircraft trajectory" means the four-dimensional (including time as the fourth dimension) flight path of an aircraft. The aircraft trajectory can be broken down as follows: [0003] (1) The lateral path of the aircraft, which is (more or less) fixed by the FMS once the flight plan (a series of waypoints) is known to the flight management system (FMS). Turn radius and heading changes at waypoi...
