Call Culdrose LARS or Lands End (St Just) for separation with the civil helicopter service and Lands End traffic, and for coasting out. Change to St. Mary's half-way there.
St. Mary's airfield is very hump-backed, like an upturned soup-plate - get down before you reach the top of the hump, or you'll float all the way down to the sea at the end of the runway.
Helpful ATC will probably suggest a low pass first, if you tell them first visit.
Nice part of the world. If there's sea-fog on the Cornish North coast, try the South coast - and vice versa.
