Method and device for assisting in the navigation of an airplane on the ground at an airport. The device (1) comprises means (14) for transmitting an alarm signal, at least if an airplane position is not on a routing zone of the airport or if the orientation bearing-wise of the airplane on this routing zone does not correspond to a particular traffic direction.

The invention claimed is: 1. A method of assisting in the navigation of an airplane on the ground at an airport, which automatically and repetitively carries out the following series of successive steps: a) the current values of a plurality of parameters-linked to the airplane are determined; b) at least one airplane position is determined, corresponding to a position of the airplane, using said current values, and its orientation bearing-wise; c) using said airplane position, said orientation bearing-wise and geometric characteristics of the airplane, characteristic positions of a plurality of characteristic points of the airplane are determined; d) for each of said characteristic points: d1) the characteristic position corresponding to a plurality of different zones of the airport is compared; and d2) if at least said characteristic position relative to one of said zones is such that a particular taxiing setpoint or a particular traffic procedure is not respected, a specific information item is transmitted; and e) e1) said airplane position is compared with a routing zone relative to a path that the airplane must follow on the airport; and e2) if said airplane position is not on said routing zone or if the orientation bearing-wise of the airplane on said routing zone does not correspond to a particular traffic direction, an alarm signal is transmitted. 2. The method as claimed in claim 1, wherein the following operations are also carried out in the step d): comparisons are made by comparing the current values of a plurality of parameters linked to the airplane with reference values; and in the step d2), these comparisons are taken into account to check whether all the taxiing setpoints and traffic procedures are respected. 3. The method as claimed in claim 1, wherein, if several specific information items must be transmitted in the step d2), these specific information items are transmitted in a predetermined priority order. 4. The method as claimed in claim 1, wherein a first airplane position corresponding to an actual position of the airplane is used as the airplane position. 5. The method as claimed in claim 4, wherein said first airplane position corresponds to the position on the airplane of a receiving antenna of a satellite positioning system. 6. The method as claimed in claim 4, wherein, in the step c), the following characteristic positions are determined: the position of the nose of the airplane; the positions of the wheels of the airplane; the position of the barycenter of the main landing gear of the airplane; the positions of the ends of the wings of the airplane; the position of the end of the vertical stabilizer of the airplane; and the positions of the jet engines of the airplane. 7. The method as claimed in claim 4, wherein, in the step d), at least some of the following zones of the airport are used: at least one shoulder zone; at least one taxiway zone; at least one stop bar zone; at least one runway zone; at least one runway intersection zone; at least one parking zone; at least one routing zone; and at least one fixed obstacle zone. 8. The method as claimed in claim 4, wherein, in the step e2), an alarm signal is transmitted if one of the following conditions is satisfied: the position of the barycenter of the main landing gear of the airplane is not on the routing zone; the position of said barycenter of the main landing gear of the airplane is on the routing zone, but the difference between the current orientation bearing-wise of the airplane and the traffic direction on this routing zone is greater than a predefined value. 9. The method as claimed in claim 1, wherein a second airplane position corresponding to an extrapolated position relative to the airplane is used as the airplane position. 10. The method as claimed in claim 9, wherein, in the step b), the following operations are carried out to determine said second airplane position: a first airplane position is determined which corresponds to the actual position of the airplane; the current speed of said first airplane position and the current yaw speed of the airplane determined in the step a), and a predetermined time interval, are used to determine said second airplane position which corresponds to an extrapolated position of the nose of the airplane at the end of said time interval relative to the current instant. 11. The method as claimed in claim 9, wherein, in the step c), the following characteristic positions are determined: the extrapolated position of the nose of the airplane; the extrapolated positions of the wheels of the airplane; the extrapolated position of the barycenter of the main landing gear of the airplane; the extrapolated positions of the ends of the wings of the airplane; the extrapolated position of the end of the vertical stabilizer of the airplane; and the extrapolated positions of the jet engines of the airplane. 12. The method as claimed in claim 9, wherein, in the step d), at least some of the following zones of the airport are used: at least one shoulder zone; at least one taxiway zone; at least one stop bar zone; at least one runway zone; at least one runway intersection zone; at least one parking zone; at least one routing zone; and at least one fixed obstacle zone. 13. The method as claimed in claim 9, wherein, in the step e2), an alarm signal is transmitted if one of the following two conditions is satisfied: the extrapolated position of the barycenter of the main landing gear of the airplane is not on the routing zone; the extrapolated position of the barycenter of the main landing gear of the airplane is on the routing zone, but the difference between the current orientation bearing-wise of the airplane and the traffic direction on this routing zone is greater than a predefined value. 14. A device for assisting in the navigation of an airplane on the ground at an airport, which comprises: first means for determining the current values of a plurality of parameters linked to the airplane; second means for determining at least one airplane position corresponding to a position of the airplane, using said current values, and its orientation bearing-wise; third means for determining, using said airplane position, said orientation bearing-wise and geometric characteristics of the airplane, characteristic positions of a plurality of characteristic points of the airplane; first comparison means for comparing, for each of said characteristic points, the characteristic position corresponding to a plurality of different zones of the airport; first transmission means for transmitting a specific information item, if a characteristic position relative to one of said zones is such that a particular taxiing setpoint or a particular traffic procedure is not respected; second comparison means for comparing said airplane position with a routing zone relative to a path that the airplane must follow on the airport; and second transmission means for transmitting an alarm signal, if said airplane position is not on said routing zone or if the orientation bearing-wise of the airplane on said routing zone does not correspond to a particular traffic direction. 15. The device as claimed in claim 14, wherein said transmission means are of audible type. 16. The device as claimed in claim 14, wherein said transmission means are of visual type. 17. An airplane, which comprises a device for implementing the method specified under claim 1. 18. An airplane, which comprises a device, such as that specified under claim 14.
