The airborne wind shear detection and alert system, fitted in an aircraft, detects and alerts the pilot both visually and aurally of a wind shear condition. A reactive wind shear detection system is activated by the aircraft flying into an area with a wind shear condition of sufficient force to pose a hazard to the aircraft.
USAir Flight 1016 was a regularly scheduled flight in the southeastern United States, between Columbia, South Carolina, and Charlotte, North Carolina. [1]: 1 On July 2, 1994, the flight encountered heavy thunderstorms and microburst-induced windshear while attempting to land, and crashed into heavy trees and a private residence near the airport.
Wind shear refers to the variation of wind velocity over either horizontal or vertical distances. Airplane pilots generally regard significant wind shear to be a horizontal change in airspeed of 30 knots (15 m/s) for light aircraft, and near 45 knots (23 m/s) for airliners at flight altitude. [3]

Pilots may decide whether to land (or conduct a missed approach) after wind shear alerts are issued. LLWAS wind shear alerts are defined as wind speed gain or loss of between 20 and 30 knots aligned with the active runway direction. "Low level" refers to altitudes of 2,000 ft (610 m) or less above ground level (AGL).
The flight, number 2431, was operated by Aeroméxico Connect and was a regularly scheduled flight from Durango International Airport to Mexico City International Airport. [1] [2] Originally scheduled to leave at 2:56 p.m. Central Time (UTC−06:00), the departure was slightly delayed when the first officer observed a fuel leak from the number one engine and asked maintenance crews to investigate.
The incident involving Flight 1722 happened just before 8 p.m. shortly after takeoff. Videos circulating online appear to show the exact moment when the bird flies into one of the jetliner’s ...
Altitude loss after takeoff or with a high power setting ("DON'T SINK") Unsafe terrain clearance ("TOO LOW – TERRAIN" "TOO LOW – GEAR" "TOO LOW – FLAPS") Excessive deviation below glideslope ("GLIDESLOPE") Excessively steep bank angle ("BANK ANGLE") Windshear protection ("WINDSHEAR") The traditional GPWS does have a blind spot.
