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.

Abstract
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.

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. - View Dependent Claims (15, 16, 18)
