Patent ID: 8433459

Claim:
An aircraft guidance system for assisting in airport navigation, comprising: at least one airport database comprising topology data of an airport, called airport DB; at least one configuration database comprising: aircraft configuration data including an aircraft type, a position of landing gear including a position of a nose wheel; a calculation of a current position corresponding to a position of a guidance point at the current instant, the guidance point being situated between the nose wheel and the landing gear calculated from the position of the nose wheel, the position of the landing gear, and from a condition according to which maintaining the position of the guidance point on a centre line of the traffic lanes makes it possible at all times to ensure that the nose wheel and the landing gears are on the traffic lane; a positioning system delivering aircraft kinematic and attitude parameters, including the position of the aircraft, its speed, its acceleration and its heading; at least one first computer which: from the airport DB, generates a 2D view of the representation of the airport notably comprising a representation of traffic lanes, of landing and take-off runways, of parking areas, and of navigation indications, and; from the positioning system and from the configuration data, generates a first representation comprising a representation of the aircraft and a symbology comprising navigation aid symbols; at least one display for displaying the first representation, wherein the system allows a first symbol to be generated by a second computer and said symbol to be displayed on the display, the symbol indicating a position of an early guidance point, corresponding to a prediction of the position of the guidance point at a future instant later than the current instant, the position of the early guidance point being calculated from at least the current position of the guidance point, the instantaneous speed of the aircraft and a heading of the aircraft.
