Hi, Miles --
Really? Any idea of when available? Most
electronic devices are made from dirt cheap bits;
dirt cheap to us also, I hope!

Sounds like an interesting approach also. One
purveyor of an AOA does use two ports at the LE,
and interprets the differential pressure. Reading
actual AOA is probably not as critical on a
Europa, so any stall warning technology may be
sufficient. While stall speed varies with weight,
the difference between solo vs. gross weight is
not as wide a spread as on, say, a 6-place
Saratoga.
