Question on Aivdyne / Garmin Integrated Avionics Packages

"Jon" wrote in message
ups.com...
I'm trying to understand how capable the new breed of integrated
avionics suites are (Aviyne Eclipse, Garmin G1000), and read somewhere
that although these systems are very capable, they don't have the
"mission capabilities" of a Proline 21. I.e., the Eclipse and Garmin
systems are ok for recreational flights but can't ever be used for
regular commercial service.

After looking at the functions of these systems, I can't understand why
this would be so? Would appreciate any input on what the Proline 21
offers that the less expensive systems don't....

Thanks in advance,

Jon


The current installations of the G1000 and Avidyne systemes only have a
single AHRS. You could still likely use them for charter though a redundant
AHRS, as planned for the Mustang, would be a good idea.

Any equippage for jets less than at least a single Flight Management System
(FMS) is rudimentary and probably lacks RSVM and other important capabilities.
A G-1000 is great in a Cessna 182, but not so red hot in a jet that goes to
flight levels.

I don't think you are comparing apples to apples. The Mustang G1000 system
will not be as limited as the 182's.

I have a lot to say about Cessna that is negative, but I haven't yet seen
anything that would lead me to believe that they are going to produce an
unsafe jet.

Tim,

An FMS has absolutely nothing to do with *RVSM* capability. I fly
around in the flight levels all day in jets that have nothing more than
dual VOR's and a very rudimentary IFR GPS.

Happy Flying!

That's why I joined "FMS" and "RVSM" with an "and."

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.

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.
