Anyone know if there is a requirement to land back at the original airfield? I am presuming not since the requirement is "a VFR cross-country flight of at
least 540 km (300 NM), in the course of which full stop landings at two
aerodromes different from the aerodrome of departure shall be made"
I did mine flying from Nantes (France) to San Sebastian (Spain) 229nm and then on to Viseu in Portugal, which was about 600nm in total.
