Well gosh Ron, didn't realize this was going to turn into a measuring cost, lol. I only have a few hundred hours of IR training given. I guess you beat me.
I can provide instrument training all day and twice on Sunday with no equipment at all (self contained PAR/ASR). Although, he does have access to an ASR down at ILM. I didn't say it was effective or the best of ideas. The point was why limit an instrument student to the same 3 approaches over and over at his home field, when you can expose him to a lot more variety if he merely plugs his ADF back in? Granted, with his most recent post, his ADF might suffer from reliability issues (which neither of us knew at the time) so the cost would go up.
Searching through Foreflight, within 60nm (up to an hour away) of New Bern, I count 8 approaches at 5 airfields he can fly with only his VOR. That's actually not too bad for instrument training. If I add ADF to his equipment, I count 26 approaches he can legally fly at 16 airfields. That's a really good variety and a lot options to choose from (real life or for training). If this spread is consistent within 500nm (a bag of gas) of New Bern, I say having the ADF increases his options substantially when on a long IFR cross country and the need to land arises. I also think having the extra piece of equipment makes flight planning for those long cross countries easier (less stressful) if one knows they're likely going to need to shoot an approach at the end (or worse, in the middle). Divert options? Yes please. Finally, he's more likely to have the ability to land at his destination. That's a pretty good Return on Investment for merely dropping a couple hundred bucks reinstalling an ADF. Sounds like a practical investment to me, but then again, I don't have as much as experience as you. :wink2:
