L'un des principaux objectifs des recherches sur les tourbillons de sillages d'avions est l'assouplissement des normes qui fixent les distances de séparation entre avions, à l'atterrissage et au décollage. Ces changements doivent en même temps assurer une amélioration de la sécurité en regard du danger que représentent les tourbillons de sillage. La réalisation de ces objectifs s'appuie en particulier sur le développement de systèmes opérationnels de détection et de caractérisation in situ des tourbillons, systèmes qui doivent être couplés à une capacité de prévision de la météorologie locale. On effectue dans cet article une revue des effets de l'environnement atmosphérique sur la dynamique des tourbillons. On décrit ensuite divers systèmes de détection et de décision développés en Europe et aux USA. On présente notamment quelques résultats de campagnes de mesure réalisées pour valider diverses composantes de ces systèmes.

Wake turbulence is a major concern for busy airports since it limits capacity. Solutions for new aircraft staggering procedures are sought which relax the current separations but keep safety on a high level. Systems which advice air-traffic control on wake-vortex behaviour under present and expected weather conditions will, hopefully, contribute to such a solution. Knowledge on transport and decay of wake vortices in the atmosphere is presented. Concepts and designs of wake-vortex advisory systems in Europe and the USA are outlined. European wake-vortex measurement and prediction campaigns are described where the components of such systems have been tested successfully.
