What is the purpose of a wind triangle in aviation?

The purpose of a wind triangle in aviation is to find the true heading that compensates for the effect of wind. The wind triangle is a visual representation that helps pilots understand how wind affects their flight path. By constructing this triangle with the aircraft's ground speed, wind speed, and desired track, pilots can determine the necessary heading to maintain the intended course over the ground.

This methodology is essential for accurate navigation, especially when flying in varying wind conditions that can alter the aircraft's path significantly. The triangle helps in calculating the required adjustments to ensure the aircraft stays on course. Therefore, the primary role of the wind triangle revolves around the relationship between the wind direction and speed, and how these factors influence the aircraft's heading and navigation.
