WIND-AID CROSS WIND CALCULATOR

Wind Aid is an aviation tool used to calculate the Cross Wind and Head Wind when the runway, wind direction and wind speed are known.

Wind Aid takes advantage of the iPhone and iPod Touch's unique touch features to provide the user with a fast, simple and intuitive user experience.

INSTRUCTIONS FOR USE

There are three input values, runway, wind direction and wind speed. These three values together determine the Cross Wind and Head Wind. To set the runway turn the runway dial until the number on the runway is the desired number.

The wind speed is set by the slider at the bottom of the screen and is further indicated by the size of the red arrow.

The wind direction is set by dragging the red arrow to a position so that the numbers at the top of the screen indicate the current wind direction.
