It might not be safe, either. IFR GPS's have an extra quality/geometry
"monitoring" algorithm called RAIM that VFR units don't have. It's
possible that you'd be OK, but it's also possible that you won't and
wouldn't know about it.

True enough, but I'm comparing my AvMap to my King VOR -- not to an
IFR-certified GPS.

With my AvMap I am able to taxi to my hangar without looking out the
windows. I wouldn't want to try *that* using my VORs... :-)

Thus, comparing apples to apples, I'm positive I could fly a much safer and
more accurate non-precision instrument approach (which is all we have here)
into Iowa City using my AvMap, even though it's technically illegal. Still,
it's nice to have the capability on board, in case of an emergency.

But I sure wouldn't do it routinely, as was the case of the pilot in Roger's
example.
