IFR GPS Options and Redundancy

[mpfef98]

My owner partners and I are restoring a 1958 Cessna 182A and are working on putting together the panel. We'd like to get it IFR certified and we're currently looking at all of our options for the IFR GPS.

We're leaning towards Avidyne since they seem to integrate better with the Dynon Skyview HDX system (from what I've read). Is there any advantage of going with a more barebones IFR GPS (like the Garmin 175) since we're planning on using the Dynon transponder and radios anyway?

Or are we overthinking this and just go ahead and get a 440 or 540 from Avidyne and call it a day?

One possible issue we may have is fitting everything in the panel, since the older 182s are a bit more constrained with regards to space. I wish Dynon would make a remote IFR GPS that just fed the data to Skyview.

I guess as with anything the answer is ....... it depends. I am in the process of a panel upgrade but I did have a 430W in the stack already. I toyed with the idea of an avidyne 440 as replacement but I still needed a comm replacement for my Narco Nav/Com as it was failing. In the end I purchased a 355 to provide be my primary GPS/Comm unit and will use the 430W as backup with plans down the road to replace the 430W with the 440. If all you are needing is a GPS then I would think the price point of the 175 is a great option.

If you'll be taking IFR check rides in the plane, some DPEs want to see ILS/VOR approach capabilities, which the Avidyne would provide. The 175 is only a GPS, which will fill the need for those approaches only.

Yeah was in the same decision tree several months ago - I went with the Avidyne IDF 440 (well its prewired with wiring harness, installed rack, and GPS antenna - it will be phase 2). The deciding factor for me was that using two Dynon Com's doesn't give you any Nav/Com functionality. Having the ILS/VOR approach capabilities was the deciding factor for me.

I went with the Avidyne IFD440 in my panel. I chose the 440 over the 540 for space reasons. I now have full IFR capability and with the new split screen function I have the IFD100 and Foreflight split on my iPad. My plane is a grumman tiger so I probably have less panel space than your 182

Our 182E is from 1961/62 the constrained space led us to use the G-GNC355 and GNC255 combo really it was a space limitation decision with us requiring two 10HDX screens just lit it up this week and haven’t flown it yet but I couldn’t be happier with the results
