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.

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.

The FreeFlight receiver coupled with your Chelton EFIS allows for LNAV/VNAV GPS WAAS approaches and IFR/G designation, allowing for stand-alone IFR navigation. When the 1101 is present, the Chelton software provides the integrity monitoring necessary for TSO-C145/146. The FreeFlight 1101 and Chelton EFIS-SV work together, providing the same functional requirements as the certified Chelton FlightLogic EFIS.

I think a FreeFlight GPS and a couple of SL30s ought to be the perfect combination and take up a heck of a lot less space on the panel. Many thanks for your thoughts.
