All Pilots need to carry out a long distance test flight that includes at least one unsupported stop to refuel. This means flying a minimum of 100km with a minimum of at least 1 fuel stop. You’ll have to track yourself with "flyskyhy" or a similar app, GPS-enabled vario, or GPS capable of delivering a 3d track. and take photos and/or videos to show your decisions and process. Have a look at this video on how to deliver proof of the run.
It’s important if you haven’t already got it lined up to do this long distance flying to fully understand what it takes including fuel stops. The deadline for submitting the data will be 4 weeks before the race.
