A primary application for this technology is found in wind shear detection for air traffic control.
Wind shear is a major safety hazard for airplanes,
in which wind speed or direction changes dramatically over a short distance.
Detecting wind shear is essential in order to select safe paths for aircraft
during takeoff and landing.
The Path-Based Shear Detection Tool (PSD) addresses the
issue of compression/expansion and en-route turbulence by giving controllers
the information they need to make arrival and departure decisions. PSD computes
headwind and tailwind along the path of all arrival corridors into an airport,
and indicates the points along that path at which excessive wind shear is
present. PSD is unique in that there are no current operational tools available
that provide path-specific wind-shear information. This path-based display is
intuitive and highlights information in a way that is easy for air traffic
controllers to use.
