Claim:
1. A method of flight management and guidance of an aircraft executed by a flight management system, the flight management system comprising an FMS sub-assembly and an autonomous guidance module independent of the FMS sub-assembly, the method comprising the steps of: generating, by the FMS sub-assembly, a reference trajectory according to three axes, lateral, vertical and longitudinal, and comprising an ordered series of segments, the aircraft flying the segments successively as it progresses, the current segment presently being flown being called the active segment, generating periodically, on the basis of the reference trajectory, a short-term trajectory, the short-term trajectory comprising a predefined number of segments of the reference trajectory, and comprising the active segment, periodically transmitting the short-term trajectory to the autonomous guidance module, generating periodically, on the basis of the reference trajectory, a long-term trajectory, the long-term trajectory comprising a predefined number of segments of the reference trajectory comprising the active segment and being greater than or equal to the predefined number of segments of the short-term trajectory, formatting the segments of the long-term trajectory so as to ensure long-term synchronization between the three axes, periodically transmitting the long-term trajectory to the autonomous guidance module storing, by the autonomous guidance module, the long-term trajectory transmitted called the stored trajectory, testing, by the autonomous guidance module, the validity of the FMS sub-assembly, when the FMS sub-assembly is valid: when the FSM sub-assembly is not valid:
