Thread creep, canyou stop at more than 2 aerodromes?
Also do the combined distances of the aeodromes on the route followed have to be > 300nm? A friend of mine said you can fly over a point, not on track to you next aerodrome, then on to the aerodrome. The total distances travelled is > 300nm with the dogleg/diversion but direct track between the aerodromes is <300nm, I disagree but my friend says it is ok.
