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.

The G1000 application in the Mustang has been announced to be RVSM
compliant. I am not sure whether a full FMS is in the cards right now, but
it wouldn't appear to be as tough to add as it is to older a less modern,
less integrated system.

Where, specifically, do you think the challenge will be? I can't figure out
what you think the bugaboo is.

I know FMS's are far less expensive today because they are basically a software
package instead of a clunky box for that express purpose.

The bugaboo I wonder about is air data processing, which is still no small feat.

I also wonder about computed steering and flight guidance, and all such things
that even have issues with the high-end systems, such as EPIC.

And, I wonder most of all about a single-pilot managing all of this. But, I
digress. ;-)

The way the G1000 system is designed takes a lot of the problems out of FMS.
In the past, there were many integration issues that the G1000 makes much
simpler because you only need to integrate with your own product. Also, you
don't have to build your own custom chip anymore, as many off the shelf
chips will work. The bottom line is that math is no longer a problem. If
your math is too intense for a single box, you add one for your new feature.

When I flew the G1000 I found it easier to manage than seperate boxes once I
learned the system. It does change you from pilot to system manager, but
you can pretty well manage everything by exception because all the faults
show up in one place.

That's silly. RSVM has nothing to do with the FMS. Every day
thousands of people and millions of boxes fly all over the world in
jets with just two vors and an ILS.

The G1000 includes a flight director and (unlike the Avidyne) can show
attitude information on any of the displays. It has all the same
capablities as other FMS systems. The only it is missing is an
integrated autopilot, but that's coming real soon now.
