The phenomenon of wake vortices has introduced a major operational constraint on airport operations, resulting in a reduction of runway capacities. Increased knowledge about the behavior of wake vortices has resulted in the development of a model of vortex behavior as a function of meteorological conditions. Based on this vortex behavior model, a Vortex Advisory System (VAS) has been designed and built. The VAS measures the primary meteorological parameter (wind) which affects vortex behavior and indicates to controllers via displays when conditions are such that more efficient runway use is possible. A detailed description of the VAS and guidelines for an operational system are given. (Author)
