i dont understand your thought process about an MDH at an airport without nav aids. if you are flying into an airport without navaids and are in the white stuff, how would you even know you above it to start an approach with your MDH in mind??
Thanks. Well, I was thinking of a GPS approach here. Fly in the soup, descent to MDH (if such exists for no navaid airport) and when you reach it, see the ground? If not, go somewhere else. But if I understand mm_flynn, that would have to be 1000ft.
As for IFR on OCAS. We all know calling up a radar service is optional, and even if I do so, this doesn't mean the other one chap has bothered to. So if I'm in clouds IFR in G airspace, how to avoid hitting someone else doing exactly the same?
Thanks IO540. The 400ft was just hypothetical. Why wouldn't a 800ft cloud base make an Elstree approach legal? Depending if I'm over built up areas, i could descend to 500ft VFR, no?
Just to recap - so I could take off in the soup from Lydd, no flight plan, drill on in the soup in G airpace on my GPS. Fly around London City TMA like you do on any VFR flight and then pop down to 1000ft when my GPS says I'm near Elstree and have a look if I see the field? This is fully legal, I don't need to speak or file with anyone?
