ADS-B on a 1982 J model

[zerotact]

Lets please ignore the fact that I have procrastinated too long on ADS-B.   I had originally planned UAVIONIX,  But it seems like Garmin has come down on the Prices and the GDL 82 is  about the same in price.   What has other owners experience been like?   I don't want an avionics shop treating this like a cat with a ball of twine, But I would consider more is there was a good reason.

[MBDiagMan]

What other Garmin units are in your panel, or expected to be added to your panel?

[RLCarter]

I went with Garmin GDL-82’s on my E and a buddies 172, it was crunch time for the FAA rebate. Really wanted the SkyBeacon for the LED light and strobe and the SkySensor for the other side for lights & ADS-B in. TailBeacon is super easy to install GDL-82 is a 3 day job

The low cost ADSB out boxes work in conjunction with your existing transponder...

If your transponder isn’t too ancient...

So... don’t forget to check the compatibility of whatever box you choose...

If you need a low cost transponder... there is a resource around here that sells pre-flown avionics... look for Alan...

PP thoughts only, not an avionics guru...

If you just want ADSB out, have no use for ADSB in (or prefer a portable in solution), and have a decent transponder, then I’d recommend tail beacon.  Low price, low installation effort, works good. If you ever think you’ll put in glass or a nice gps or a new transponder, then you probably should do an gtx345 or gdl82 now and avoid doing adsb twice.

One other consideration could be outside the country... the 978mhz systems (tailbeacon and gdl82) are only ADSB capable in the US.  Some countries don’t require adsb yet so you can still go, but when they do, 978 won’t work.

Do you have a certified Nav source in the plane such as a Garmin 430W?

You got a better recommendation if he does?  It seemed like 4 or 5 years ago a waas would help, but now it seems most of them come with their own (tail beacon, gtx345w, etc).  Just curious where you’re going... I like your outside the box options sometimes!

Were you gonna suggest a gnx375? Maybe kill two birds with one stone?  Bit more money but loads of capability.

King KT-74’s can be had for ~1600 if you look... maybe that’s the thought?

edit: nevermind- that’s about what a gdl82 costs as well.

No, there is no existing gps in the plane or any Garmin products...

 the beauty of the sky beacon / tail beacon is that the A&P could sign off on the install, keeping you from having to pay for a trip to the avionics shop.. 

I believe the gdl - 82 is like this as well..

 Replacing the transponder in the panel would most likely not prevent this ..  this would I do not want to turn a $2000 problem into a $20,000 bill.

I just didn’t know if there was a solution I was not aware of..

The gdl is more involved than tail beacon just based on location.  The tail beacon is really easy.  If you want cheap and easy, that’s it.  The gnx-375 is ~$6k. Gonna be $1-$2k to install.  Youd get adsb in/out and full gps/waas with lpv approaches and traffic and weather Bluetooth to your ipad.  It’s also on the higher ICAO adsb frequency, so no future problem in canada, mexico, etc.  It’s a lot of capability.  You could sell your old transponder too.

Anyway, as I see it, those are the best options.

[Yetti]

The tail beacon is great if your Transponder is strong, but eventually the tube is going to go out in the 76.   only single band.  And you still have an old altitude encoder.

So

There are three levels of GPS =  Enroute,  ADSB, IFR Approach certified.

The Lyxnx 9000 offers some great integration for around 5 AMU plus install.   https://sarasotaavionics.com/avionics/lynx-ngt9000   Install should not be the 20 AMU you are afeered of

The Trig 22 are dual band.  Needs at least ADSB level GPS input source.  About 4 AMU for the T22 and TN70- space considerations since Remote mount.

Tail beacon offers a temporary fix since most of the avionics shops are still busy.  But it comes with limitations and not really a long term solution

 

[MBDiagMan]

Sounds as if all you seek is compliance with no desire for IN.  If that’s the case, the Tail Beacon will get the job done easily if you currently have a good transponder.
 

I really like having both IN and OUT from the transponder with a 345 in the Mooney and an Appareo in the 140.  I really shudder to think about flying without it.  If you don’t want to spend the money for IN don’t fly with it because you will then want it.

[Yetti]

In can be solved with a couple hundred bucks with a Stratux and a Android tablet or phone.

[MBDiagMan]

I’ve yet to see a Stratus/Stratux provide in on a 430/530/650/750.

Because the 430 needs GDL 88 and the STratux puts out GDL 99 format.   That said the Stratux talks to the tablet.   Even with the fancy panels people still have tablets and phones.   The phone tablet helps with the party questions of How long would it take you to fly there?

[MBDiagMan]

I fly with an iPad with IN from the transponder in both my planes, but if all I had to receive IN were a Stratus/Stratux I wouldn’t have traffic on the 430.  Only on the IPad.  The Mooney has the 430W and a 345 while the little taildragger has an Appareo which only gives IN on the iPad, but there’s no panel Navigator anyway.  The taildragger is not used for a traveler so the iPad gets me by.  The Mooney on the other hand, I want traffic on the 430.  Depending on a stratus and a pad in a traveling airplane doesn’t seem adequate to me.  There’s a lot to be said for redundancy as a side benefit.

I have the same 430w and -345 setup as well and like it a lot.  Even the traffic on tge 430w screen is nice.  It wouldn’t be the end of the world to go with a tail beacon for out and a sentry for in on an iPad though.  As long as you’ve got traffic and weather on something, it’s pretty darn good.

I've been very happy with my decision to buy the TailBeacon.  For ADSB-In I have a Scout and use my iPad; a MUCH better display than the 430W.  All in, a $2600 solution.

Did you apply for the rebate? Considering you have to give 1/2 back as taxible income at the end of the year I just dropped mine.

But you have to fly around with you nav lights on? Does that dim you warning lights (like gear unsafe etc?)

We did, ended up doing 2 flights on each plane over Charlie, Cessna was missing a digit in the tail number and the Mooneys flight was short by less than a minute

Not that I can notice; all lights are quite visible even in bright sunlight.

?? He'd have to have a pretty bad alternator if the nav lights affected his main bus voltage!

There’s a circuit that automatically dims the annunciator lights in the J, I think that’s why he asked.
