whats to stop you just touring the whole of somerset and dorset then landing at Exeter and Dunkeswell? or for that matter just flying round in circles for an hour and a half at 100kts? still covered 150NM
...the fact that it would be so boring?
In theory yes you could just spin around in circles but personally I quite enjoy the nav, and the CAA seemed happy enough with it to sign off my license. Just another idea though, what are the rules concerning GPS on qualifying cross countries now? That would seem much more on the borderline of the rules to me.
