Guide

This is aimed primarily at the club level pilot who wants to know what to expect for the next week.

Data is calculated from the GFS model data using the RASP calculations daily.

Wind strengths are graded for aircraft suitability.

Wind speeds are average wind speeds, gusts will be higher.

Conditions are graded for how the average pilot will feel about them.

Great flying conditions for XC

Turbulent XC flying conditions

Dangerous flying conditions

Likely Poor XC flying conditions
