Anybody had any experience with the AI information on the Anywheremap
system?

It would be interesting to know what PDA is used, if there is anybody.

That works well with relatively draggy and stable airplanes. There is
no gyro in the 296. It infers bank information from rate of turn
information, and that information is of course delayed. In something
nice and stable like a Cherokee (or, for that matter, any single
engine Cessna with struts and fixed gear) this works adequately well -
certainly well enough to shoot a no-gyro PAR in 1000 and 2 - because
the delay time between banking the wings and turn indication on the
GPS is not sufficient for anything really ugly to happen. But the 210
is a different beast - with retractable gear and no struts, it's more
like the Bonanzas and Mooneys than it is like most Cessnas. By the
time you get turn indication on the GPS, you might already be in a
spiral. It might work OK with a very sharp pilot familiar with the
plane, a well-trimmed airplane, and smooth air but it's not much of a
plan.
