I wondered how long it would be before the old 4 (actually 3) miles from the point of departure was quoted. This has never been the definition of a cross-country flight except very specifically in relation to the privileges of an AFI. For TeeS benefit, the EU definition of a cross-country flight is to be found in FCL.010:
‘Cross-country’ means a flight between a point of departure and a point of arrival following a pre-planned route, using standard navigation procedures.
As to the definition of 'landing', Miriam Webster has it as:
an act of returning to the ground or another surface after a flight
So returning to a hover is, of course, not a landing
