I’m sure this has come up before, soon I will join the 21st Century and install ADSB out.
Of course part of the installation is to amend the AFM, and honestly I don’t think we have one do we?

Here it is per item # 403 in the TCDS. This eliminates CAA Form 309 per Cessna Service Letter SLN-40.

Thanks,
Sure leaves out a lot doesn’t it

Yes it does! There is also a Operations Manual in the library that has much more information but to my knowledge, it is not a required document to be kept in the airplane, only the AFM.

I forgot that my own AFM is marked with a Tentative Approval. Per the TCDS, it is acceptable for aircraft up to and including the 1947 model and I also noticed it actually has more info than the Final version. I am attaching it here it case it helps. Mine was from April of 47 and the final was in March of 48 with 2 different approvers as well.

Have you zeroed in on your ADSB Out equipment? We have fellow members who have everything from tailBeacon/skyBeacon to full blown glass, so plenty of experience around here. It's surely "revealing" when you check FlightAware or similar and realize that your every movement...EVERY Movement is now watched and recorded. Mac

It will most likely either be the tail beacon as I have Whelen wing tip strobes, or the Garmin GDl-82.
Garmin is cheaper and I have a 327 xponder, but it requires more of an install, holes in the airplane etc.

Still trying to wrap my head around why the tailbeacon is an STC and requires a 337, for what is not a major modification.

FWIW, my GDL82 has performed flawlessly...installed in '18 (My Txp is the 327 also). Harness fabrication is no biggie, but if you order pre-fabbed it's a (relatively) easy install, 'though you do have to add the GPS antenna on top and run that coax. The tailBeacon is very attractive for simplicity of installation & they seem to work well. Mac

I went with the Stratus ESGi. It also required a GPS antenna installation. One of the reasons I went that route was that my existing Narco transponder was starting to fail and I was looking at a new transponder either way so I went that route which was the cheapest way to get ADSB In/Out at that time.

Mac I'm reminded of the old song in which George Jones opines "And when your phone don't ring it'll be me, It'll be me not calling you, crying like I used to do A-crawlin' on my hands and knees". So Mac if you're not seeing N76446 on FlightAware or FlightRadar 24, it's me who hasn't installed ADS-B Out.

If ADS-B is the measure by which we have joined the 21st century, I haven't. I must be the only guy taking seriously "EVERY Movement is now watched and recorded". Actually, I'm blessed to be able to fly in all the airspace I've been used to flying in without legally needing ADS-B so I haven't spent the money. Part of that is I bought the 120 to enjoy the opposite end of the spectrum from which I made my living. I will say that there are times when I do feel exposed to traffic, but I'm always looking outside, not inside.

Agree, John. While there are a lot of positives that come with residing in the "near metro" area we're in, the slim (and, seemingly ever dwindling) available airspace for true recreational flying is a bummer. Trying to enjoy flying and "dodging" boundaries to go where I wanted had become more fun than I could stand. Good for you -- hang on to those open skyways as long as you can! (At the risk of getting in trouble with mods, I'm reminded of even another old country song: (Paraphrased) "You ain't much fun since I quit drinking...or since I had ASD-B forced on me!" Seriously, it really isn't all that bad . Mac
