OverviewThis page is output from an experimental set of applications to determine a potential flight distance (and view spatially). A Google Map version is here.

Check the top of the chart for the valid period, along with the date/time when last created to determine if it shows the latest information.
This is currently experimental, and as calibration and experimentation take place, the output may not be completely reliable. It is provided on an as-is basis and is produced daily. The morning run (for today) is normally ready by around 09:30 - other runs may take longer.
How CalculatedThe RASP task calculators are used to calculate a 'closed' triangular task, based upon a given 'polar' and for a given 'thermalling percent'. The input parameters used are shown on the chart.
How to UseThe chart provides a spatial view of locations (mainly gliding club airfields) that have had radial task calculations in a number of directions run from that location. The calculations are done for the whole day and so the maximum distance is used wherever in the day it was best.
What you are looking for are areas that show increased distances to indicate lines of better conditions. These may offer areas to consider when task planning.
