What combination of factors BEST indicates windshear?
Understand the Problem
The question is asking to choose the best combination of factors that indicates the presence of windshear, which is a sudden change in wind speed or direction in a short distance. The correct answer will include the key indicators of windshear's impact on an aircraft.
Answer
Sudden changes in wind velocity or direction indicate windshear, often linked to jet streams, mountain waves, temperature inversions, frontal surfaces, and thunderstorms.
Wind shear is indicated by a sudden change in wind velocity and/or direction. It can be horizontal, vertical, and is associated with weather conditions such as jet streams, mountain waves, temperature inversion layers, frontal surfaces, and thunderstorms.

Wind shear is indicated by a sudden change in wind velocity and/or direction. It can be horizontal, vertical, and is associated with weather conditions such as jet streams, mountain waves, temperature inversion layers, frontal surfaces, and thunderstorms.
More Information
Wind shear is especially dangerous during takeoff and landing.
Tips
Wind shear is often used incorrectly with the different turbulence types.
