Impact of Individual and Dynamic Wake Vortex Separations on Airport Capacity

For many airports the capacity is limited by minimum separation distances especially for approach and landing due to the possible hazard generated by wake vortices. In order to alleviate capacity limitations, separation rules have to be improved without reducing safety. Based on simplified hazard areas dynamic wake vortex separations can be derived taking into account atmospheric conditions and actual aircraft pairing. This concept is applied to parallel runways in comparison to the single runway case for cross wind and headwind conditions
