Abstract
The device (1) comprises means (4) for determining parameters relating to the next intersection of the current traffic lane and a head-up display system (7) for presenting symbols illustrating these parameters.
Claims10
A method for aiding the ground navigation of an aircraft on an airport, according to which method the following series of operations is carried out in a repetitive manner:
- a) the current position and the current heading of the aircraft are determined automatically;
- b) with the aid of said current position and of said current heading, as well as of information arising from an airport database (3), the current traffic lane of the airport, on which the aircraft is situated, as well as parameters relating to the next intersection of the current traffic lane are determined automatically, said parameters comprising at least:
- the position of this next intersection;
- and
- the distance between this position and the current position of the aircraft;
- and
- c) a first symbol (8) illustrating said current traffic lane, and a set (E) of second symbols (20, 21, 22, 23) illustrating respectively said parameters relating to the next intersection, which have been determined in step b), are presented with the aid of a head-up display system (7), overlaid on the environment existing in front of the aircraft,
- wherein, in step b):
- the following parameters relating to the next intersection of the current traffic lane are determined, moreover, with the aid of said current position and of said current heading, as well as of information arising from said airport database (3):
- characteristics of the traffic lanes which cross the current traffic lane at this next intersection;
- and
- the angles between these traffic lanes and said current traffic lane;
- and
- in order to determine the parameters relating to the next intersection, the following successive operations are carried out:
- α) with the aid of the current traffic lane (S1) and of said airport database (3), the set of intersections (I1, I2) existing on this current traffic lane (S1) is determined;
- β) from among the set of these intersections (I1, I2), the intersection (I1) closest to the front of the aircraft is selected with the aid of the current heading and of the current position of the aircraft, as well as of the positions of said intersections (I1, I2), which arise from said airport database (3);
- and
- γ) for the closest intersection (I1) thus selected, the following are determined with the aid of the airport database (3):
- the characteristics of the traffic lanes (S2, S4) which cross the current traffic lane (S1) at this closest intersection (I1);
- and
- the angles between these traffic lanes (S2, S4) and the current traffic lane (S1).
