What constitutes "sovereign" airspace?

[jalbert]

Hello
Any of you ATC people know the answer to this?
Is it the national territory out to the 12 mile(or is it 2 mile?)limit as per fishing rights etc?Or is it the entire area of an FIR?
The SOTA for example,who "owns" that?In the Shanwick(UK)OCA but controlled by Shannon(Ireland)and comprising international waters?
Maybe the answer is in the Annexes but I can't find it.
Thanks for any help.
Moderator-is this the best place for this?

The Shanwick Oceanic Control Area consists of international airspace delegated, (by ICAO), to the United Kingdom and Republic of Ireland, (separately), which both states combined to form a single OCA. The Shannon Oceanic Transition Area, (SOTA), is part of Shanwick OCA airspace, but has been delegated to the Shannon FIR as their radar cover extends far enough to the south to provide a radar control service. (It also extends quite a ways to the north of the Shannon FIR - but they haven't been delegated that bit, yet...). Brest and Reykjavik also have smaller portions of the Shanwick OCA delegated to them for the same reason.

The procedural control and overall administrative aspects are the responsibility of the UK and are provided by National Air Traffic Services Ltd. (NATS) from the Prestwick OACC. (Part of ScOACC). The H/F comms aspect is the responsibility of the RoI and is provided by the Irish Aviation Authority's Ballygireen Aeradio Sation, near Shannon. The name "Shanwick" denotes the provision jointly of the ATC service by Shannon (Ballygireen) and Prestwick, on behalf of ICAO.
