Actually Evo there is an IAP where you fly from. I believe the Police Helo and Air Ambulance are the only ones allowed to do it and they have a discreet frequency to do it on!
I'm doing the IMC at Lee-on-Solent, not Goodwood. With some of the aeroplanes based there (esp rotary) I'd guess there is some kind of unofficial procedure based around the 'secret' NDB that doesn't seem to appear on the charts. I know a procedure was drafted and submitted (by my IMC instructor) but it ain't available to us now
I believe the Goodwood VOR/DME procedure requires permission from the CAA.
AFAIK only the Air Ambulance King Airs use it, but they are flown by two CPL/IRs with good kit and there's no way the rest of us would be allowed to. Minima must be quite low because they manage to arrive in some really bad wx sometimes.
