摘要
Wake-vortex hazards are a huge threat in aviation. These hazards are well accepted in the vicinity of airports (both departure and arrival). But also a number of en route incidents have happened in the past. Current wake-vortex mitigation strategies are based on static distances (in space and/or time). In future air traffic management concepts of Single European Sky Air Traffic Management Research and NextGen, these static distances will be replaced by dynamic separation strategies. Furthermore, concepts for self-separation of aircraft are described. This paper will discuss the work at Technische Universitat Braunschweig, where a new concept for wake-vortex hazard mitigation has been developed. The basic idea of the new concept is that only a criticality parameter will be transmitted between aircraft to ensure a safe separation even within new self-separation concepts. The criticality parameter will give an indication about the severity (and therefore criticality to the following aircraft) of the vortices. Additionally, Technische Universitat Braunschweig will install wind-turbulence measurement equipment onboard its research aircraft. This installation will be also be described, and the possible usage will be discussed.
