Patent ID: 8346464

Claim:
A method for aiding ground navigation of an aircraft on an airport, the method comprising: a) determining, by a set of information sources, current position and current heading of the aircraft; b) determining, by a first determination unit, according to said determined current position and said determined current heading, and according to information obtained from an airport database, a current traffic lane of the airport on which the aircraft is situated, and parameters relating to a next intersection of the current traffic lane, wherein said parameters relating to the next intersection include the following: position of the next intersection; and distance between the next intersection and the current position of the aircraft; and c) overlaying, by a head-up display unit, on an environment in front of the aircraft, a first symbol illustrating said determined current traffic lane, and a set of second symbols illustrating the determined parameters of the next intersection, wherein: the following parameters relating to the next intersection of the current traffic lane are determined by the first determination unit; characteristics of traffic lanes that cross the current traffic lane at the next intersection; and angles between the crossing traffic lanes and said current traffic lane; and the following steps are carried out by the first determination unit: α) determining, according to the current traffic lane and the information of said airport database, a set of intersections on the current traffic lane; β) selecting from among the set of intersections, an intersection closest to the front of the aircraft, according to the determined current heading and the determined current position of the aircraft, obtained from the information of said airport database; and γ) determining, according to information of the airport database ( 3 ): characteristics of the crossing traffic lanes at the selected closest intersection; and angles between the crossing traffic lanes and the current traffic lane.
