Patent ID: 8224504

Claim:
A method for updating the position of an aircraft during a flight, the method comprising: performing a series of operations with a flight management system, the operations including: determining a first position of the aircraft from inertial data and from data supplied by a satellite positioning system; determining a second position of the aircraft from inertial data and from data supplied by a radio-navigation system using an inertial and radio navigation position calculating device; and selecting a most accurate value of the first and second positions, that will be used as a new position by the flight management system; and generating an updating position with an updating system that includes a manually-operated fly over updating device for updating through flying over, a manually-operated radar updating device for updating through radar, and an automatically-operated take off updating device for updating upon takeoff, wherein during an update implemented by the updating system: the updating position generated by the updating system during such an update is supplied to the inertial and radio-navigation position calculating device, for determining the second position, and the second position, thus determined by the inertial and radio-navigation position calculating device using the updating position, is selected as a new position that will be used by the flight management system, wherein during a manual update performed by a crew member of the aircraft using the fly over updating device or the radar updating device manual update means, the method further comprises: cancelling automatically a selection of sensors, other than inertial sensors, that supply data for determining a position of the aircraft.
