Wisconsin's Great Lakes Skydiving 

Free Spot Calculator

This spot calculator is free for anyone to use. It has proven to be a good tool in helping to determine the first spot of the day at Great Lakes Skydiving, serving Chicago, Madison, and Milwaukee. The spot is calculated based on 'total displacement' and will not give a jump-run directly into the ground winds or the upper winds. However when the difference in total displacement and the upper winds are greater than 90 degrees an inverted version is calculated that runs opposite to the total displacement but more into the upper winds entered.

Directions of use

The upper winds that appear in the form are the average of 'JOT' and 'DBQ', these values are meant for a spot over Great Lakes Skydiving. Please get the winds aloft information and enter it into the form below. Please don't forget to also enter the ground wind information. The speed should be entered in 'knots' and the directions in 'degrees' from magnetic North. You can find 'winds-aloft' information at the following website aviationweather.gov (midwest winds aloft)

This tool has proven to be a good help in determining the first spot of the day. Keep in mind that at best it is only as accurate at the winds aloft forecast and is not always 'spot on'. Please use at your own risk. Wisconsin's Great Lakes Skydiving wishes you a safe and enjoyable skydive!
