Abstract: A method of generating a flight plan including a number N-1 of segments SGi, i being an integer number between 2 and N. Segment SGilinks an auxiliary departure position to an auxiliary arrival position according to a route. The route is a straight line defined by a list of auxiliary route positions. Each route is stored in a database onboard the aircraft. The method includes a coupled determination of an auxiliary arrival position that is part of the auxiliary positions of at least one of the routes and of a route followed by the segment SGi+1. The coupled determination is produced from an auxiliary departure position and a route Ri, followed by the segment SGi.

Abstract: The invention relates to an aircraft navigation aid method.

Abstract: The field of the invention is that of the generation of an aircraft flight plan. The invention more specifically relates to a method of generating a flight plan enabling an aircraft to link a departure airport AD to a destination airport AA. The flight plan consists of a number N?1 of segments SGi, i being an integer number between 2 and N. The index i uniquely identifies the segment SGi of the flight plan linking an auxiliary departure position PADi to an auxiliary arrival position PAAi according to a route Ri. The route Ri is a straight line defined by a list of auxiliary route positions PARi,k, in which k identifies the auxiliary route positions. The routes Ri are stored in a database BDR onboard the aircraft. PAD1 is a geographic position (of the departure airport for example) AD, PAAN is a geographic position (of the arrival airport for example) AA, PAAi and PADi+1 are combined for any integer i between 2 and N?1.

Abstract: The invention relates to an aircraft navigation aid method. It comprises the following steps consisting in: a) computing a feeler line according to the wind, in other words the ground path that the aircraft would follow if a turn at the maximum rate applicable to the current flight phase of the aircraft were to begin at that instant, b) displaying on a navigation screen the feeler line and a ground path to be captured, in order to determine how to place the aircraft in a turn in order to optimize the capture of the path to be captured.
