I noticed that SkySight has changed its Route Forecast Section and gives auto suggested routes but with different color schemes: red, green and yellow (or close enough). Does anyone know what these color codes represents, suggested distance for difference sailplane classes perhaps? I searched and could not find anything. I believe the potential distance section is for an 18 meter ventus.

Thanks in advance
It's meant to be a proxy for difficulty.
Red - Longer and more complex
Green - Shorter and easier

All of the calculations in the program, including PFD & Route forecast vary according to the performance/pilot factor you set in Settings - Account. The default is 100.

Thanks - big help, it is a great new feature

Does the route forecast suggestions factor in other forms of lift like ridge lift and convergence as well, or is it just based on thermal lift predictions?


Yes, with some caveats. It will only use a ridge or a convergence as a speed boost on a thermal flight - it will be unlikely to route find in zero-thermal conditions, it lacks the creativity required. It also requires the ridge to be more significant than say, most ridges in the East Coast USA, which are on the limits of what models can resolve.

If you see the lift on the XC Speed chart, that's the same data the route finder is using.
