l'A380 va peut-etre avoir du plomb dans l'ailes cause des turbulence de silliage l'OACI a fait publier et envoyer des recommandation que voici 🏴‍☠️...ça circule déja dans plusieurs forum aero

Reference : T 13/3 – 05-0661.SLG 10 November 2005 Subject : Wake vortex aspects of Airbus A380 aircraft

The ad hoc group of experts under the auspices of the United States Federal Aviation Administration (FAA), EUROCONTROL, the Joint Aviation Authorities (JAA) and the manufacturer is currently developing guidance on wake vortex separation criteria for the A380. It is now anticipated that this guidance will be made available in early 2006. In the meantime, analyses and flight test data available to the group have raised concerns about horizontal and vertical wake turbulence spacing criteria for approach, landing, departure, and en route operations of the A380 relative to other aircraft.

Guidance is presented as follows:

1. Departure spacing: a) one additional minute to be added to all separations listed in Procedures for Air Navigation Services – Air Traffic Management (PANS-ATM, Doc 4444), paragraph 5.8, when an A380 is the leading aircraft; b) one additional minute to be added to the separation in PANS-ATM, paragraph 5.8.5. 2. Horizontal spacing: a) where both aircraft are established on final approach, 10 NM between an A380 and any other following aircraft; b) 15 NM minimum radar spacing for all other phases of flight, including enroute, between an A380 and all other aircraft operating directly behind at the same altitude or less than 300 m (1 000 ft) below. (See alsoparagraph 3 below.)

3. Vertical spacing: Vertical spacing guidance will not be completed for several months. There are indications, however, from the initial analysis of data that wake vortex from an A380 may be encountered by aircraft flying 300 m (1 000 ft) below at greater strengths than from current aircraft of the heavy wake turbulence category. Because it has not yet been possible to establish the level of hazard associated with these wake vortices, offset tracks or additional vertical spacing is advised until the final vertical spacing guidance has been established.

Les turbulences de ce type derrière un gros porteur doivent sans doute être très elevées, il faudrait comparer avec celles d'un 747 - 400 ou celle d'un gros porteur Antonov pour voir si celles ci sont fondamentalement différentes, c'est typiquement un sujet d'expert, à trancher par un CdB qui connaitrait le truc par coeur - ils ajoutent une minute aux procédures antérieures visiblement

Un recent accident aux USA sur un Airbus A300-600 d' American dans les turbulences d'un autre appareil à JFK semble prouver que ce probleme n'est pas neutre je suis d'accord avec vous

Ca semble tout de même plus facilement gérable de distancer les avions que de gérer les arrivées de 500 passagers à la fois...
