Which approach speed adjustment is recommended during landing in wind shear?

In wind shear conditions, it's crucial to adjust the approach speed to maintain control and ensure a safe landing. Increasing the approach speed by up to 10 knots is recommended because it provides a safety buffer against sudden changes in wind speed and direction that can occur in a wind shear scenario. Wind shear typically involves abrupt variations in headwinds or tailwinds, which can significantly affect the aircraft's performance during the critical phases of flight such as the approach and landing.

By increasing the approach speed, the pilot can counteract potential loss of lift or gain associated with unexpected wind changes. This buffer supports better control and allows for a more stable approach, reducing the risk of stall or other handling issues that might arise from a sudden drop in airspeed due to a downdraft or wind shift. This adjustment is generally safer than remaining at normal approach speed, as it accounts for the erratic nature of wind shear and helps ensure that sufficient energy and lift are maintained for a safe landing.
