Base Speed and Climbing Speed Graphs The speeds below are speeds that you can hold for the given distance when on level ground with no wind.
The plot then shows suggested speeds for all distances from 10 to the chosen distance with increments of 10 (Hover the mouse over the graph to see the speeds).
The corresponding climbing speeds are also shown.
Forever Speed:
Speed for a distance of 40 units:
Speed for a distance of 400 units: The graph plots from 10 units to distance:

The base speed graph is a hyperbola with horizontal assymptote y = forever speed, that passes through the two given points. The climbing speed is then computed from this hyperbola using the same relative climbing speed that you have entered on the main page. The mathematics of computing the climbing speed is described in the help page. It is hard to know how good this model is, but I have found it predictive.

Use the input points to create a route. Any currently open route will be cleared.
Use the input points to add markers along the current route. The first six characters of the text are used for the marker label.

Required format: Each line contains either lat, lon or lat, lon, text.

Set Predicted Wind

Use the forecasted wind.
Example: A SW wind (from the SW) is 225 degrees.
Example: For wind changing at 24 hours, enter the new values on the 24 hour line.

Set Past Wind

Use the past forecasted wind.
Example: A SW wind (from the SW) is 225 degrees.
Example: For wind changing at -24 hours, enter the new values on the -24 hour line.
