Tim,

O.K., I see your original point, now.

As a data point, I fly jets all day that do not have FMS, but are RVSM
equipped and do not lack any other "important" capabilities.



Oh, I know. There are lots of air carrier round dial birds that are RVSM
compliant. But, they had the requiste air data computers to begin with
when they rolled off the assembly lines circa 1970-80, or so.

I don't know for a fact, but it seems that making one of these VLJs
RVSM-compliant won't be an easy task, and may not be done by the OEM at
all.

With a bird coming off the assembly line today without a full-press
FMS/LNAV suite, I would wonder about the other expensive stuff required to
be RVSM-compliant.
