Select a ship first. Then choose:
angle of bank wind direction and speed atmospheric sink/lift rate wing loading/gross weightNote that the units you choose are used for all output and need not be the same as those in the actual data set. All conversions will be handled for you.
Then click on 'Show' to see the best speed to fly under these conditions, or select another option to see an analysis.
Note that if you have data of your own on your hard disk or Web site and you have downloaded this calculator to that site as well, then you can use your own data. If you do that, the data must be in a subdirectory just under this one by the name 'xydata' and in the proper format.
If you would like to see your glider's data on MY list, please send the data in the proper format to me. Be sure to indicate units!
