One last go-around on the Chelton system interfacing with the Garmin 480.
I spoke with Josh at Direct to Avionics. Josh works with Peter and Kirk to
answer technical questions at Direct to avionics and they sell the Chelton
"Sport" and Chelton "Pro" systems to the experimental aircraft market.
Josh confirmed the Chelton "Sport" system does not interface with the Garmin
480, even though it has a serial bus like the SL-30. Complete SL-30
functionality is not available on the 480 serial bus (unfortunately). As an
alternative, the Garmin 430 can partially interface with the Chelton "Sport"
via an ARINC 429 converter. I'm not sure what functionality is missing when
interfacing with a Garmin 430.
The Chelton "Pro" system does interface completely with the Garmin 480.
I've seen this system and it is very impressive. When connected to a 480
and SL-30, the "Pro" HSI shows two bearing pointers for Nav1 and Nav2 with
switching to select between Nav1 or Nav2 for the CDI and OBS. The "Pro"
system is about twice the price of the "Sport" system. I only saw one Pro
system at Lancair avionics and it was going into a Lancair IV turbine
aircraft.
In my previous discussions regarding interfacing a Chelton system with the
Garmin 480, I was referring to the Chelton "Sport" system which most
experimental aircraft builders choose if they go for a Chelton system. I
believe it's price is around $25K (two displays) and the "Pro" system is
around $50K.
Hope this level of detail helps. I appreciate everyone's feedback.
Thanks

Chris,
Just to clear up something John wrote that is incorrect about the
statement " The Chelton can not even display nav data (like localizer /
glide slope or VOR) from the480." This statement is incorrect. The 480
has the same output provided on the SL-30/SL-40 located on page D-23 if
the installation manual. The 480 was the UPS CNX-80 designed by UPS the
same folks that created the SL30/40. So in short you can display and
control navigation function for ILS/LOC/VOR on the Chelton through a
serial data bus.

>From what I've learned building my Lancair Legacy and going around with

Most
panels I see at Lancair that are using the Chelton system rely on the
FreeFlight GPS and flight planning is done in the Chelton user
interface. A
480 or 430 is back-up only. Seems like a bit of a waste. The Chelton
can
not even display nav data (like localizer / glide slope or VOR) from the
480.
I love the 480 and have decided to go with Grand Rapids interfacing to
the
480 and SL-30. Flight planning will be done on the 480 and the Grand
Rapids
unit will display the whole flight path with the current leg colored
magenta. HSI will show both Nav 1 and Nav2 in different colors. And
with
Chelton, I also miss the "pan". On the 480, you can scroll ahead of
your
current location to look at airspace ahead or on either side of your
flight
path and get data on "nearest" waypoints to the pan location.
The Chelton screen is beautiful with very high resolution and good
sunlight
visibility. It's nice to have all these choices.

Hello all,
I've been following Tim Olson's RV-10 project for a while and he uses a
GNS-480 in his panel in addition to the built-in GPS of the Pinpoint
GADHRS.
>From what I read, the 480 pretty much sits dormant in the background
while
the built-in GPS does most of the work. Presumably, the 480 is there
because it's the only IFR-certified GPS of the Garmin line (and in his
plane). Presuming someone was to use the FreeFlight GPS option to meet
the
IFR requirements, would one be losing any functionality that the 480
offers?
I've gone through a majority of the feature/operation videos on the
Chelton
site, and the system is really thorough in its navigation options,
flight
planning, etc. Would a pilot miss not having a 480 in the panel by
relying
on the Chelton, or are they similarly capable?
I do see the benefit of having the 480 as a GPS backup in case of
EFIS/FreeFlight failure, to be sure, but thought I'd pose the question.
I
suppose there's always the tried-and-true radio navigation as well :-)
Thanks and best regards,
Chris

John,
This is true for full function as listed in the Chelton Pro operator
manual, but you still get basic function with the 480 such as auto tune
and VOR/LOC/GS from ONE radio on the RS232 if selected. You will not
get function like the pro on two radios independently. The 480 does put
out on a 232 line the data for VOR/LOC/GS. I'm not sure if the 480
provides you with TIS data from the GTX-330. I just looked it up and
the information in Appendix B of the Garmin 480 installation manual
states the function I listed. To be clear, the Pro system can
differentiate between multiple input and outputs for VOR and auto
tuning, the sport can not. If you are only using ONE external radio for
these functions, based on what I just read the Garmin 480 does support
these ASCII Binary data lines like the SL30 and 40. My personal
experience with the CNX-80 uses RS232 for this information with the
MX-20 but I think that it uses a proprietary language when talking to
the MX20.
