Calculate crosswind, headwind, and tailwind components from wind speed, wind direction, and runway heading. This calculator is useful for aviation planning, runway wind checks, and quick wind component estimates.
Wind speed:
Enter the wind speed from the report or forecast.
Wind direction:
Enter the direction the wind is coming from, in degrees.
Runway heading:
Enter the runway direction or aircraft heading in degrees.
Wind components:
The calculator finds the angle difference, then estimates crosswind and headwind or tailwind components.
A crosswind calculator is useful for aviation planning, runway selection, flight training, weather checks, landing preparation, takeoff planning, and understanding wind reports.
This tool is for estimating wind components only. Pilots should always use official weather, aircraft limits, training, procedures, and instructor or operational guidance.
Your result shows the estimated crosswind component and headwind or tailwind component. Crosswind is the sideways part of the wind relative to the runway or heading. Headwind helps slow groundspeed, while tailwind increases groundspeed and may affect takeoff or landing distance.
Crosswind is calculated as wind speed multiplied by the sine of the angle between the wind direction and runway heading.
Headwind is calculated as wind speed multiplied by the cosine of the angle between the wind direction and runway heading.
A negative headwind value means the wind has a tailwind component.
Yes, approximately. For example, runway 27 is about 270 degrees and runway 18 is about 180 degrees.
