Try looking at it as a charter helicopter operator. Under the current "rules" Battersea Heliport (10 000 movements a year) is shut from July until September. I flew in Athens as part of the broadcasting team for the 2004 Olympics and there was none of this total load of b******s.
If you are a commercial operation (flying school, air taxi etc) I suggest you go to the authorities and demand you fees back for that period as the authorities are effectively stoppping you trading.
