Hello, Nigel --
Thanx for the additional info on the panel installation; I have that yet to
plan out.
As to RMI's uEncoder instrument, I was thinking VFR. For IFR, you're exactly
correct, and in which case the uEncoder itself is then arguably a waste. For
even VFR, I erred in suggesting the ASI be eliminated, as I don't intend to
(lack of aural stall warning being one reason). I would argue, though, that
an altimeter is optional for VFR with the uEncoder, or alternatively a 2-inch
non-sensitive item intended for ultralights is a cheap backup.
I would like an IFR Europa, but I live in the area of the USA (Great Lakes)
where the icing conditions get so bad so often that for 5 months of the year
IMC in a Europa would be a bit bold (laminar flow airfoil; where to mount a
heated pitot?). The Great Lakes area is where an ATR-72 commuter turboprop
iced up so bad they lost it in 30 minutes or less of exposure. The leading
edge boots and prop de-ice worked OK, but ice around mid-chord caused aileron
reversal. I used to fly IFR often, but not so much since a few years ago
when descent to the IAF thru a Mickey Mouse broken layer over Lake Erie iced
the wings, the prop, and clogged the induction air scoop all in a few
minutes. 'Nuf for me!
