1. Closed Velocity Triangle
The aviation wind triangle connects three vectors: Air Vector (TAS & True Heading), Wind Vector (Wind Speed & True Dir), and Ground Vector (Ground Speed & True Course).
GroundVector = AirVector + WindVector
Remember that National Weather Service winds aloft forecasts are reported strictly referencing True North poles. Never enter magnetic course tracks into wind computer solvers without converting to True first!
