Le trafic aérien va encore augmenter...
Il ne servira à rien de déplacer les nuisances, il faudra se déplacer autrement!
Même si vous ne lisez pas l'anglais, les graphiques parlent d'eux-mêmes!
Et voyez la place de la Belgique.

Conventional aircraft navigation in European continental airspace was based on the use of ground based navigation aids (i.e. VOR/DME/NDB) and the resultant ATS route structure was anchored on these point source aids, being totally dependent upon the location of the ground facilities. The system was inflexible in terms of both geography, which resulted in an inefficient use of the available airspace, and capacity, which meant that it could not easily be expanded to absorb the forecast growth in demand. When B-RNAV was introduced, forecasts indicated that air traffic movement would more than double by 2015.

The inherent inability of the ATM service to continue to meet the users’ expectations in terms of improved operational flexibility, punctuality and reduced costs, or to fully exploit current and emerging technologies, established the need for the development of a strategy for the introduction of new concepts for the operation of the future ECAC airspace, whilst maintaining the existing quality of ATS and associated safety standards.
One of these concepts was Area Navigation (RNAV) - a method of navigation which allows aircraft to operate on tracks joining any two points, within prescribed accuracy tolerances, without the need for the overflight of specific ground facilities. RNAV was identified by ICAO FEATS as the future navigation system in the European region.
In 1990 the ECAC Transport Ministers agreed a strategy for air traffic control in Europe in accordance with ICAO FEATS. The strategy included requirements for the mandatory carriage of on-board RNAV equipment from 1998. Aircraft not equipped and approved for RNAV operations would not be permitted in RNAV airspace.
