Study Notes
Wind Direction and Velocity
- Airports measure wind direction relative to magnetic north, rounded to the nearest 10°
- Wind direction is measured in a 360° system
- Wind speed is measured in knots (approximately 1.15 miles per hour)
- Wind information is always preceded by "wind"
- Each digit of the wind direction and velocity is enunciated individually
- If instruments are faulty, "estimated" is used
- If wind direction is fluctuating, "variable" is used
- If wind speed changes rapidly, "gusts" and the peak speed are mentioned
Examples
- North wind, 15 knots: "Wind three six zero at one five"
- East wind, 10 knots with gusts to 25 knots: "Wind zero niner zero at one zero gusts to two five"
- Variable southeast wind, 12 knots with gusts to 35 knots: "Wind one five zero variable at one two gusts to three five"
