Also, there's been a lot of talk about not being able to zero altimeters
at
some high elevation airports. This is puzzling also. The Kollsman range,
which is also the basic baro range in the Viper's CADC which drives the
Viper's altimeter in both ELECT and PNEU backup, is aprox 22.00 inches on
the low side and 32.00 inches on the high side. (I had to check this out
with some buddies of mine, as I'd forgotten the range in the Kollsman
myself!! :-)

Wow. OK, I was dead wrong on that (so were many others, but I think I was
the first :-) ).
