The International Cessna 170 Association

The L3 Lynx has “ATAS” which is the aural traffic advisory.

Not sure if it can export traffic into a Garmin 650.

It is not an inexpensive solution to ADS-B, but I put one in my 170 and it works nicely.

According to L-3’s Support/FAQ page it can. That’s an impressive transponder.

Well, I think I finally have a plan of attack. I have gone back and forth quite a bit, but I'll be installing a GNX 375 GPS/Transponder and G5 HSI and and will update to a SL30 or GNC 255 nav/com radio that will also drive the G5 HSI. This will save me quite a bit compared to a GTN 650 and new ADS-B transponder (as well as panel space).

I won't actually update the nav/com till next year's budget allows. But this path let's me make a large jump in functionality this year.

I found this video today and wanted to share it because he does a great job of answering my original question about do I need my ground based nav instruments. My final config will have it, but I really like how this guy explained it with the regs.

Garmin makes the GI-275 round dial vs. G-5 square. Since my panel is original I plan to install it or the UAvionix AV-30 PFD. Pretty amazing for an old tail dragger!

I installed the GNX 375 along with a GNC 255 and a GNC225 in March. I’m very happy with the result. I have the indicator switchable between the 375 and the 255.

Good luck with the upgrade.

I like his presentation also... however he speaks from the standpoint of an avionics sales person rather than from the flight-operations point of view, IMO.
I don’t like the idea of relying on communication w/ATC to navigate to an ASR or PAR approach. I don’t know if he’s looked at it .... or if he has only heard of them...but ASR and PAR approaches are not common anymore and even at the fewer airports that can offer them, they are not approaches with which most pilots have experience. The ASR is pretty simple but unless you’ve practiced PAR approaches ...they can be very difficult. It ain’t like in the movies.

BTW, anyone who’s flying around with minimum equipment might consider a quality hand-held comm/nav radio with VOR/ILS capability. I keep on within reach. An electrical failure is always possible. (And single-engine IFR should always be thought of in the light of “where can I find basic VFR to which I can descend?” IMO

Since I’ve already installed an Appareo ESG transponder, and I’d like to have a second comm, my upgrade plan is a GNC 355 GPS/Comm driving a G5 HSI (replacing the vacuum DG). I plan on keeping my KX-155/KI-209 for ground-based nav, so I shouldn’t even need an indicator switch.
