Abstract:

The requirement for wake vortex avoidance is well established. Encounter of heavy aircraft wake vortices by lighter aircraft trailing by even minutes can be disastrous, especially if the encountering aircraft is flying near the ground in a near-stall condition, i.e., landing or departing. The report provides a conceptual design for a predictive-detective system to predict the movement and decay of aircraft-generated vortices in air corridors near the air terminal using forecast meteorological conditions, periodically update the prediction by monitoring vortex movements, provide a forecast of separation requirements for optimum aircraft spacing according to prevailing vortex conditions, and provide a waveoff or hold capability for rare cases when vortices stray unpredictably into a hazard zone.
