Tail Beacon X with AV30 Question
Up here in Canada the requirement for ADSB is still a few years out for GA and from the last I read "no sooner than 2026"
With an eye on that and planning trips down south I'm looking at options for my 337G and the UAvionix Tailbeacon X and AV30 combo made the short list. Currently fly it mostly VFR but would like to modernize the panel a little (see pic for current setup) it would be nicer and more comforting to have some modern glass in front of me regardless of IFR or VFR. The Tail Beacon X will make my aircraft compliant for any ADSB mandate for Canada and allow us to fly in the US so that solves that issue. Now regarding the AV30 and the Autopilot etc. Our Aircraft has the Cessna Navomatic 300 and gotta say it does the job and have been pleasantly surprised at how well she works and don't want to replace it at the moment. I have a quote from my AME which I think is reasonable but need to clarify a few things next week when I get it back from annual inspection. Maybe I'm jumping the gun but I thought it would be good to get some more 337 specific knowledge as this will be his first time doing this upgrade to a 337 and want to make sure everyone's on the same page. 1. Will I be able to remove the old Attitude indicator or will I need to relocate it? maybe (ADF indicator hole) 2. Can I ditch my Garmin 327 Transponder entirely? 3. Can it couple to the Auto Pilot with Heading and or GPS (Apollo CNX80) Thanks in advance and will post what I learn next week and as I do some more digging. |

— relocate it. Needed for autopilot. 2. Can I ditch my Garmin 327 Transponder entirely? — yes, if tailbeacon STC says so. 3. Can it couple to the Auto Pilot with Heading and or GPS (Apollo CNX80) — No. AV30 STC not eligible to drive autopilot. It will accept and display GPS track via RS232, if CNX80 has RS232 output with matching format. |

Also they have this AV-APA https://uavionix.com/product/av-apa-experimental/ Quote:

“Thank you for that, I reached out to Uavionix for clarification as it sounds like my CNX80 could control the transponder negating the need for the AV30 and therefore find a compatible EFIS that could drive the autopilot - Any suggestions?”
—verify CNX80 can control xpdr by reading installation manuals for both CNX80 and TailbeaconX. —Adding AV30 gets you independent AOA, backup airspeed/alt, and electric attitude (AHRS) and GPS track in case vacuum fails. That’s why I put one in my bird. I don’t fly a lot of hard IFR but the peace of mind on a dark and stormy night makes it worth it to me. —AV-APA is not likely to be compatible with Cessna ARC autopilots. Currently it supports STEC 20/20/40/50 only. —Every 337 owner with a navomatic 300/300a/400/400a is awaiting someone to STC a modern digital autopilot compatible with modern EFIS. We’ve heard “it’s just around the corner in a year or two” for over 5 years now. We’ve offered our aircraft to Garmin and Genesys and Dynon…we’ve offered to buy the equipment outright…and as of today, the only autopilot upgrade is 1980s tech Century, BK, and the most modern, the STEC 55x which is 20 yrs old. Lots of autopilot upgrade threads on this board. Best bet today is probably Aspen displays with a DAC GDC31 converter connected to your existing autopilot. |

Chatting with my mechanic it still seems like a good fit for getting some glass upfront. The last few times plunging out over the Pacific to break through a marine layer didn't sit well with me. That being said it worked fine and did the job. Having some modern glass and a "backup" Vacuum would be great.
This is the response to some questions I asked UAvionix. Quote:
Asking about timeline if the AV-APA would be certified and compatibility with the Navomatic 300. Quote:
