What is the impact of negative windshear?

Negative windshear occurs when there is a sudden change in wind speed or direction that can adversely affect aircraft performance, particularly during takeoff and landing phases. The correct answer accurately describes one of the impacts of negative windshear, which is the association with a decrease in tailwind and the presence of downdrafts.

When negative windshear is present, an aircraft may experience a reduction in tailwind or even a headwind condition, which can disrupt the lift generated by the wings. This can lead pilots to encounter unexpected downdrafts, reducing altitude and airspeed, ultimately increasing the risk of stalling if not managed appropriately. The presence of downdrafts in negative windshear can create a hazardous situation, as it may cause the aircraft to lose lift suddenly, challenging the pilot's ability to maintain controlled flight.

In contrast, other impacts related to windshear, such as increased turbulence, can occur, but they are not inherently linked only to negative windshear conditions. Turbulence can be caused by a variety of atmospheric phenomena and is not as directly representative of the danger posed by negative windshear. Similarly, negative windshear does not cause higher atmospheric pressure; rather, it is a dynamic condition that can affect the
