Method for adjusting the joining trajectory for an aircraft

Abstract

The invention relates to a method for adjusting a flight plan rejoining trajectory of an aircraft. A method is provided for adjusting a flight plan rejoining trajectory of an aircraft, the method being implemented in a flight management system (1) of the aircraft. In a first step, the rejoining trajectory (TPMC) comprises a guidance setpoint holding point to be reached situated in the extension ofa guidance setpoint, and set manually or automatically, the guidance setpoint no longer being necessarily maintained when this setpoint holding point is passed. This first step can be preceded by a step of rejoining a guidance setpoint or a step of searching for the intersection of the current guidance setpoint trajectory with a segment of the flight plan.

Description

technical field [0001] The field of the invention is that of aircraft navigation and guidance. More specifically, the field of the invention is the determination of so-called re-engagement trajectories when a pilot has to deviate from his or her initial flight plan. A flight plan is to be understood as the lateral and longitudinal references corresponding to the planned flight of the aircraft. Background technique [0002] Currently, when a pilot needs to temporarily deviate from his or her flight plan (for example, either at the request of air traffic control, or in response to unforeseen circumstances such as weather disturbances), he or she uses an option called a "selected "guidance fix" to interrupt navigation along the flight plan. In this case, the forecast assumptions along the flight plan no longer faithfully and reliably reflect the future progress of the flight. Specifically, for a heading fix, the trajectory length of the future point at which the destination ...

This degree of freedom can be shown to be ineffective in operationally obtaining the pilot's desired tactical trajectory
