Right now, the CNX-80 does not give vertical guidance, but that is
promised in software version 2.0, hopefully to be approved by Q3/2004.
That software v2.0 has been in flight test since Q4/2003.
I'm unaware of any box nearer than the CNX-80 to LPV capability.

that,
the guidance remains the same.

Has
WAAS been approved for operational use? How many boxes have the
functionality described in 1-1-20?...I think the CX-80 does.
