Method and Device for Assisting the Ground Navigation of An Aeroplane in an Airport

A method for aiding the ground navigation of an airplane (A) in an airport, according to which method the series of following successive steps is carried out, in an automatic and repetitive manner:

• a) the current values of a plurality of parameters of said airplane (A) are determined;
• b) with the aid of said current values, a first position (P1) relating to the airplane (A) is determined;
• c) this first position (P1) is compared with at least one prohibited zone (zl);
• and
• d) if said first position (P1) is situated in said prohibited zone (zl), at least one alert signal is emitted, wherein in step b), a first position (P1) is determined which corresponds to an extrapolated position of the nose (4) of said airplane (A) after a particular time interval starting from the current instant, during the ground navigation of said airplane (A) on the airport, and in that said prohibited zone (zl) is a predetermined prohibited zone of the airport.

A device for aiding the ground navigation of an airplane in an airport, said device (1) comprising:

• a set (2) of information sources for determining the current values of a plurality of parameters of said airplane (A);
• calculation means (3) for determining, with the aid of said current values, a first position (P1) relating to the airplane (A);
• comparison means (6) for comparing said first position (P1) with a prohibited zone (Zl);
• and
• alert means (9) for emitting at least one alert signal if said first position (P1) is situated in said prohibited zone (zl),
• wherein it comprises, moreover, a database (5) which comprises at least one predetermined prohibited zone (Zl) of the airport, and which is connected to said comparison means (6), and in that said calculation means (3) are formed so as to determine a first position (P1) which corresponds to an extrapolated position of the nose (4) of said airplane (A) after a particular time interval starting from the current instant, during the ground navigation of said airplane (A) on the airport.
