Glider pilots frequently use computer based maps showing approved turning points and controlled airspace for planning cross-country flights.

Commercial programs are available for the purpose, but run only on Windows. Maintenance of airspace and turning point data has to be done at client level.

jsTaskPlan is a viewer written in JavaScript and HTML 5, which will run in any modern Web browser. It uses an interactive map, using Google Maps, and obtains controlled airspace data and standardised turning point locations from a variety of publicly available sources.

The user plans the task interactively by clicking on marker icons on the map.

Currently it is only useable on larger screens (1100 px plus width) with a conventional mouse. It is intended to add touchscreen and tablet support as a further development.

jsTaskPlan has been tested in the following browsers:

• Firefox 42 (Windows and Linux versions)
• Chromium 45 on Linux *Chrome 46 on Windows *Microsoft Edge
• Internet Explorer 11
