From: "Chris In Madison" --> Avionics-List message posted by: "Chris In Madison" Hello all, Other than it being a larger, more easily read "analog" display, is a CDI a necessity with Garmin's SL30? I see that it has a CDI-like indicator in its display, although I'm guessing (without looking at the manual) that this display doesn't handle glide slope, only VOR and the like. What would I be missing out on if I chose not to connect a CDI?

You mentioned the glide slope. The display does not include the glide slope. Though the OBS can be set on the SL30 for the desired VOR radial, it requires a combination of a button pres and more than one knob turn so is less convenient than a single knob on a CDI. With a CDI, you can use a L-R output to couple to an autopilot to follow the needle of the CDI. If you are ever going to want an instrument rating and use it, the CDI will fit into your scan and be more readible than the SL30 display. I'm not even sure that the display qualifies for IFR use. Hope this is some help. The old timers will probably also respond with comments.

From: "Chris In Madison" --> Avionics-List message posted by: "Chris In Madison" Thanks for your thoughts, Richard. I can see where it's quite useful now. I've been considering an EFIS with CDI components in the software, but I'm debating whether or not I should have an actual CDI as a backup. I think you've answered that question for me.

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 -------- Chris Owens Waunakee, WI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=60403#60403 ________________________________ Message 5 _____________________________________ Time: 12:14:36 PM PST US From: "6440 Auto Parts" Subject: Re: Avionics-List: Re: CDI necessary with Garmin SL30? --> Avionics-List message posted by: "6440 Auto Parts" I purchased a new md200-306 for my SL30/Grand Rapids system which I have decided not to use since I will be installing a 3 screen system with dual ahrs. If anyone is interested in purchasing it I will sell it for what I paid which was around $1450.

It's worked great, and I've not seen any interference to speak of. What I'm considering now is taking it one step further. Instead of worrying about GPS batteries, or putting the little GPS on the glareshield, I'm thinking of buying a bluetooth serial port similar to this one: http://www.pc-mobile.net/bta.htm The only catch is, this one is for 4800baud, when the GPS is 9600 baud, so I'll probably have to step up to something like this: http://www.iogear.com/main.php?loc=product&Item=GBS301 that can be configured for multiple data rates. I know it's not the cheapest way to go...my bluetooth GPS only cost $55 or so, plus shipping, but it would be nice to have hardwired power, and rely on my existing GPS that is really reliable, and also not have to carry anything portable along with me. Has anyone else done something similar? It seems like it should be pretty simple. What I'm really hoping for is to find someone who's done similar with some components, instead of buying a whole device. It seems the right things are out there: http://www.free2move.se/pdf/F2M03GLA.pdf http://www.national.com/pf/LM/LMX9820A.html -- Tim Olson - RV-10 N104CD - Flying do not archive ________________________________ Message 7 _____________________________________ Time: 08:23:41 PM PST US From: "John Richardson" Subject: RE: Avionics-List: FAO Chelton users: outboard GPS options --> Avionics-List message posted by: "John Richardson" Chris >From what I've learned building my Lancair Legacy and going around with Direct to Avionics (Chelton rep to experimental) the Chelton system does not interface with the Garmin 480....only the SL-30/SL-40 via serial 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.
