With your IMC you can get radar vectors to the ILS at Ronaldsway (class D), but you really don't want to be doing that in true IMC in a little cessna.
Surely that's the whole point of having an IMC rating so long as he can be out of the clag at his minimums? Not that I'm advocating planning a flight into known bad weather etc but it's there to be used if the situation dictates.
