Wind shear has significant effects on the control of an aircraft, and it has been the only or a contributing cause of many aircraft accidents. Sound movement through the atmosphere is affected by wind shear, which can bend the wave front, causing sounds to be heard where they normally would not.
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. A predictive wind shear detection system is activated by the presence of a wind shear condition ahead of the aircraft. In 1988, the U.S. Federal Aviation Administration (FAA ...
Wind shear has a significant effect during take-off and landing of aircraft due to their effects on steering of the aircraft, and was a significant cause of aircraft accidents involving large loss of life within the United States.
A fiery January crash of a B-1 bomber in South Dakota was caused by multiple crew failures, terrible winter weather and a last-minute brush with wind shear that resulted in all four members ...
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).
Wind shear has a significant effect on the control of aircraft during take-off and landing, [70] and was a significant cause of aircraft accidents involving large loss of life within the United States.
Jet stream produces horizontal wind shear at its edges, caused by the different relative air speeds of the stream and the surrounding air. Wind shear, a difference in relative speed between two adjacent air masses, can produce vortices, and when of sufficient degree, the air will tend to move chaotically. [10]
The accident also led to the discovery of downbursts, a weather phenomenon that creates vertical wind shear and poses dangers to landing aircraft, and it sparked decades of research into downburst and microburst phenomena and their effects on aircraft. The concept of downbursts was not yet understood when Flight 66 crashed.
