  • Vortex advisory system
    Patent number: 4137764
    Abstract: The separation between aircraft approaching a common runway is minimized by measuring the existing wind conditions at a preselected point relative to the runway threshold and basing a prediction of the movement of wake vortices on the measured conditions. The prediction of vortex movement is based upon a vortex advisory algorithm prepared from a plot of wind conditions which predictably remove vortices from the flight path.
