Patent ID: 8755995

Claim:
A method for realigning the position of an aircraft during flight, the aircraft having a first system for forming a realigned position and a second system which represents a navigation system, the method comprising the steps of: a) in said first system: a1) generating a position of the aircraft; a2) recording in a memory the generated position, together with a date-stamping associated with the generated position and which represents a moment of generation of said position; b1) actuating a triggering unit by an operator request for realignment, wherein a realignment position is determined by said navigation system, together with a realignment date-stamping associated with the realignment position that takes into account elapsed time between the actuation of said triggering unit and receipt of the realignment position and date-stamping by said navigation system, wherein the realignment date-stamping corresponds to the date-stamping associated with the generated position of the aircraft in said first system, and b2) transmitting said realignment position and said associated realignment date-stamping from said navigation system to said first system; c) extracting from said memory in said first system, the generated position and an associated date-stamping corresponding to said realignment date-stamping; d) calculating a vector difference between the extracted position and said realignment position in said first system, the vector difference representing a realignment bias; and e) adding the realignment bias, in said first system, to a new position of the aircraft, taking into account an auxiliary realignment bias, so as to obtain said realignment position of said aircraft, wherein: each of said steps a), c), d) and e) is carried out in a plurality of first systems, with each first system generating the position of the aircraft, said second system is connected to each of said first systems, and said second system transmits said realignment position and said associated realignment date-stamping to each of the first systems, and said realignment position is obtained according to the realignment bias, in which the realignment bias represents the vector difference calculated for each corresponding first system, taking into account the auxiliary bias.
