<p>The device has a generating unit to generate a flight path (2) including a flight segment associated with a flying altitude. A digital noise database contains volumes (40) to be avoided, where an aircraft avoids penetrating into the volumes to avoid generating undue noise on ground at predetermined sites. A computing unit has a main memory containing instructions for enabling display e.g. two- or three-dimensional display, of a representation (41) of the volumes and the generated path on a display screen as an overlay on a representation (31) of a terrain provided by a digital terrain model. An independent claim is also included for a method for defining a flight path to be followed by an aircraft to reach a destination.</p> |
