Now, Paul... Don't succumb to the temptation to start hanging all sorts of crap all over your new Ercoupe.
Realistically, though, an electric vacuum pump would cost more than the (rather high) cost of replacing your DG and AI with electric units. By the time you got it 337'd and custom installed, at least. Not to mention the weight. The venturi is a good solution. Of course, in real IFR it might well ice up on you... Someone tossed the vacuum instruments out of 06H at least a decade ago. No great loss. There is a vertical card compass which is easier to deal with than the old kind. And the GPS performs yeoman service as a DG substitute, with automagic resolution of wind drift to boot (be sure your refresh rate is set to the fastest available on your GPS for such use). I don't use an artificial horizon... ...I look at the real one :-) And if I can't see it, I don't fly. Greg At 06:11 AM 10/11/99 -0700, Paul M.
