..... As
well as having to carry ADF, VOR and DME for IFR flight in controlled
airspace, anyone wanting to fly at or above FL100 (note that that's
equivalent to 10,000 ft, perhaps not what US pilots are used to for =
flight
levels) needs B-RNAV (B for Basic). The only economical way of meeting =
the
B-RNAV requirement is to carry a TSO-C129a class A GPS receiver. I =
have in
the back of my mind that, ironically, it has to be class A1 (approach
capable) because B-RNAV imposes some extra requirements beyond the A2 =
spec,
but I'm not sure.=20

Interesting, if that A1 need is indeed the case.
Approach capability seems an odd requirement in equipment mandated only =
for high-altitude flight.
But logic shouldn't be applied recklessly to regulations, should it?
