What's this circuit charge for? I've never heard of an airport charging for the use of the airspace. Landing, sure. T&G, obviously. Missed approach, okay I can live with that. ATC/Eurocontrol en-route charges for IFR flights, fine. But a circuit charge? Is there a legal basis for that?
I checked the VFR flight guide and it only mentiones a 16.50 UKP landing fee (for up to 1.5 MT), nothing else.
