Crosswind&Headwind Calculator

⚠ Disclaimer:This calculator is a supplemental planning tool only and does not replace official crosswind calculations. Always verify against your aircraft's POH/AFM demonstrated crosswind component. The pilot in command is solely responsible for making go/no-go decisions.

Wind & Runway Information

结果

Crosswind = Wind Speed ×sin(angle)|  Headwind = Wind Speed ×cos(angle)

在上方输入您的跑道航向、风向和风速，计算器将立即为您提供侧风、逆风和顺风分量。

It uses the same sine and cosine math as an E6B flight computer. If you want to learn how to use this calculator and other factors, bookmark this article and keep on reading.

要点

The crosswind component equals wind speed times the sine of the angle between the wind and the runway.

Always calculate using the gust value from the METAR, not the steady-state wind.

Compare your result to the maximum demonstrated crosswind in your aircraft’s POH before committing to a runway.

This calculator gives the same answer as an E6B, without the setup time.

How to Use This Crosswind Calculator

输入您的跑道航向。 Pick the runway number from the dropdown (27 = 270°) or type the magnetic heading directly. For the most accurate result, use the published heading from your airport diagram rather than multiplying the runway number by 10.

Enter the wind direction in degrees magnetic. Pull this from the ATIS,METAR, or tower broadcast. Remember, wind is always reported as the direction it blows from.

Enter the wind speed in knots. If the METAR shows gusts (example: 18G25KT), enter 25. You want to plan for the worst case, not the average.

Read your results.您将看到带有左或右标签的侧风分量、逆风或顺风分量以及风与跑道之间的角度。

The Crosswind Formula

Two formulas handle the entire calculation:

Crosswind component= Wind Speed × sin(θ)

Plug that in:
