A method for constructing a flight trajectory of an aircraft, comprises a step of computing a sequence of state vectors (Ei) representing the trajectory of the aircraft; a state vector (Ei+1) being determined on the basis of the state vector (Ei) preceding it by means of: a step of computing the speed components (Vi+1), consisting in determining: a flight setpoint, by selecting an objective navigation point, a joining strategy adapted to the flight setpoint and to the flight domain (DV) by means of a predefined library (LSr) of joining strategies, a manoeuvre by means of the flight domain (DV), making it possible to follow the joining strategy towards the flight setpoint; a step of computing the other components of the state vector (Ei+1), on the basis of the components of the speed vector (Vi+1) and of the preceding state vector (Ei). |

1. A computer implemented method for constructing a flight trajectory of an aircraft, deployed in a flight management system, said flight management system configured to determine, on the basis of a flight plan advised by the pilot, an objective navigation point sequence (SPNO), an objective navigation point being characterized at least by a geographical position, and configured to determine a flight domain (Dv) consisting of a set of parameters defining an aerodynamic behaviour of the aircraft, said flight trajectory being defined as a sequence of state vectors, the method comprising two successive steps:
first computing, with the flight management system, state vectors representing the trajectory of the aircraft; the state vectors having as components at least a time (ti), a geographical position (Xi,) of the aircraft and components of a speed vector (Vi) of the aircraft; a state vector (Ei+1) being determined on a basis of the preceding state vector (Ei) preceding it in a sequence by:
computing the components of a following speed vector (Vi+1), including:
determining a flight setpoint, by selecting an objective navigation point from the objective navigation point sequence (SPNO), thendetermining a joining strategy adapted to the flight setpoint and to the flight domain (Dv) by means of a predefined library (Lsr) of joining strategies, thendetermining a manoeuvre by means of the flight domain (Dv), allowing the aircraft to follow the joining strategy towards the flight setpoint, andsecond computing, with the flight management system, other components of the state vector (Ei+1), on a basis of the components of the following speed vector (Vi+1) and components of the preceding state vector (Ei) in the sequence proceeding it in the sequence. |
