Claim:
1. A method of guidance of an aircraft during a low-altitude flight, the method comprising: a) constructing with the aid of a flight management system a low-altitude flight trajectory corresponding to a flight plan, the flight trajectory being transmitted from the flight management system to a guidance system, the flight management system being able to construct at least one new low-altitude flight trajectory corresponding to a new flight plan; and b) guiding the aircraft with the aid of the guidance system, along the low-altitude flight trajectory termed the active flight trajectory, which comprises additional steps of: storing in at least one first memory of the flight management system, the active flight trajectory along which the aircraft is guided, as well as any new flight trajectory; storing in at least one second memory of the guidance system, the active flight trajectory along which the aircraft is guided, as well as any new flight trajectory; identifying, with the aid of an associated identification code, each flight trajectory transmitted from the flight management system to the guidance system; and periodically transmitting from the guidance system to the flight management system, the identification codes for the flight trajectories recorded in the second memory of the guidance system.
