>>haven't heard of wind shear lately<< The FAA took steps to deal it... jsc.nasa.gov One of those accidents occurred at Dallas-Fort Worth Airport on August 2,1985, when a powerful microburst caused the crash of a Delta Airlines Lockheed L-1011 jetliner with 137 fatalities. That accident triggered a Congressional mandate to the FAA to initiate a research/training effort toward curbing the windshear hazard. In 1986, the FAA and NASA launched a joint program to develop the essential technology for detecting and avoiding microbursts. The FAA undertook an aircrew training program that focused on windshear recognition and procedures for recovering from its effects. FAA also led the development of ground-based windshear detection instruments, including the Terminal Doppler Weather Radar (TDWR) now being installed at 45 major U.S. airports; developed by Raytheon Corporation, the TDWR can accurately measure wind velocities in terminal areas and generate real-time aircraft hazard displays that are updated every minute.
