Final Report - CREDOS (Crosswind-Reduced Separations for Departure Operations)

Project ID: 30837
Funded under: FP6-AEROSPACE


This is the final report of the CREDOS project. The International Civil Aviation Organization (ICAO) separation standards for landing and take-off were implemented in the 1970s to protect an aircraft from the wake turbulence of a preceding aircraft. However, research has shown that the transport and persistence of wake vortices are highly dependent on meteorological conditions, so that in many cases the ICAO standards are over-conservative. By developing a full understanding of wake vortex (WV) behaviour in all weather categories, separations could be reduced under certain suitable conditions. The CREDOS project was studying the operational feasibility of this approach by focussing on the situation for take-off under crosswind conditions.

The report initially refers to the project background, along with the partners involved. It explains the concept that CREDOS was based on and then goes on to state the objectives and the structure of the research. The document then describes the work performed under each one of the five work packages, the results obtained and recommendations for future research.
