Device and a method for constructing a flight path in order to reach a destination

摘要

A device (10) for defining a flight path (2) enabling an aircraft (1) to reach a destination (B), said device (10) including a digital terrain model (21) and a display screen (30), and being provided with generator means (15) for generating a flight path (2) including at least one flight segment (3) associated with a flying altitude. The device (10) includes a digital noise database (20) having volumes that are to be avoided, said device (10) having a computer (11) with a main memory (13) containing instructions for displaying on said display screen (30) and as an overlay on a first representation (31) of said terrain as provided by said digital terrain model (21): a second representation (41) of said volumes to be avoided; and a flight path (2) that has been generated by using said generator means (15).

主权项

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.
