Thomas - wie gehts. Long time since Berlin
Southampton is in class 'D' and linked to the airways system. So, the clearance you get will be:
"Cleared to (destination), via (Departure - they have published SID's), squawk ........."And you'll probably get that when you call for start, or just prior to taxi. Inbound you shouldn't get dumped into class 'G', again as the CAS is all connected.
That's it, no different to operating out of most class 'C' or 'D' airports on the continent. Now, parking, handling etc - that's a different matter
