Device and a method for constructing a flight path in order to reach a destination
First Claim
1. A device for defining a flight path enabling an aircraft to reach a destination, said device comprising:
- a digital terrain model;
a digital noise database having volumes to be avoided, each volume to be avoided being a zone in which an aircraft emits noise generating a sound footprint above a predetermined threshold value on the ground at predetermined sites;
an aircraft database supplied by the manufacturer of an aircraft and characterizing the noise generated by said aircraft;
a legislative database containing the regulations to be complied with in terms of noise emissions;
a display screen;
generator means for generating a flight path including at least one flight segment associated with a flying altitude; and
a computer with a main memory containing instructions enabling the following to be displayed on said display screen as an overlay on a first representation of said terrain as provided by said digital terrain model;
a second representation of said volumes to be avoided; and
a flight path that has been generated by using said generator means;
wherein by executing said instructions said computer generates said noise database from said aircraft database and said legislative database.

8. A method of defining a flight path in order to reach a destination, the flight path including at least one segment associated with a flying altitude, by using a digital terrain model, a digital noise database, and a display screen, together with generator means for generating said flight path, the method comprising:
-
generating said noise database from an aircraft database characterizing the noise generated by an aircraft, and from a legislative database containing the regulations to be complied with in terms of noise emission; constructing a generated flight path during a flight path construction step using the terrain model and the noise database; displaying terrain as a first representation on a display screen; and overlaying volumes to be avoided from the noise database into which an aircraft should avoid penetrating in order to avoid generating undue noise on the ground at predetermined sites, and the generated flight path on the display screen over the first representation of the terrain during a comparison step. - View Dependent Claims (9, 10, 11, 12, 13)

15. A device for defining a flight path for an aircraft, the device comprising:
-
a display screen; a computer linked to a terrain model and a noise database, the noise database containing data relating to the locations and shapes of volumes to be avoided by the aircraft, where each volume to be avoided represents a portion of air space to avoid to reduce excessive noise at predetermined sites on the ground, the computer configured to generate the noise database using an aircraft database characterizing the noise generated by said aircraft, a legislative database containing the regulations to be complied with in terms of noise emissions, and a meteorological database; and a flight path generator configured to generate a flight path to a destination, the flight path containing at least one segment with an associated flight altitude; wherein the computer is configured to command the display screen to display;
(i) a first representation of the terrain model, (ii) a second representation of volumes to be avoided overlaying first representation, and (iii) the flight path overlaying the first representation. - View Dependent Claims (16, 17, 18)
