Which factor is responsible for most weather-related accidents?

Wind is identified as the factor responsible for the majority of weather-related accidents in aviation. This is because wind can significantly impact an aircraft's performance, stability, and control during critical phases of flight such as takeoff, landing, and low-altitude maneuvering. Strong gusts, crosswinds, and turbulence can lead to loss of control or difficulty in maintaining the correct flight path, making it a primary cause of mishaps.

While temperature changes, visibility issues, and rain can also contribute to aviation accidents, they are typically considered secondary factors compared to the immediate and severe effects that wind can have on aircraft handling. Turbulent conditions, strong headwinds, or tailwinds may complicate flight operations and lead to accidents more frequently than the other weather-related factors. This underscores the importance of wind awareness in flight planning and operations as pilots and air traffic controllers must account for wind conditions to ensure safe air travel.
