Abstract:
1. A method for determining a shifted circular segment based on an initial circular segment, the shifted circular segment being shifted by a shift distance in a direction of shift, the direction of shift being to the right or to the left of an aircraft, the initial circular segment being characterized by a centre, a radius and a direction of rotation, the initial circular segment belonging to an initial flight plan comprising a set of consecutive initial segments, each of the initial segments comprising an initial final point, the shifted circular segment belonging to shifted flight plan comprising a set of consecutive shifted segments, each of the shifted segments comprising a shifted final point, the method comprising: determining, using a computer dedicated to flight management, a shifted final point terminating the shifted circular segment, based on the initial final point terminating the initial circular segment, through a shift of the initial final point determined based on the shift distance in the direction of shift, through the use of a straight line passing through the centre of the initial circular segment and the initial final point of the initial circular segment; and determining, using the computer dedicated to flight management, the shifted circular segment based on the initial circular segment by construction of a circular segment between a shifted final point associated with an immediately preceding shifted segment and the shifted final point associated with the shifted circular segment.
