ADSB compatibility with Avare

[The Wandering Wench]

I fly a low-end E-LSA (translation - used to be called a fat ultralight before being registered.) I almost never fly in airspace that requires ADSB, so didn't buy a unit. I'm now planning to do some flying that WILL require an ADSB unit and have gotten conflicting and confusing information about what unit to buy. One thing that jumped out at me was being told to be sure that whatever unit I buy is compatible with BOTH the Nexus Android on which I use Avare AND the Avare app. Any information on this - and possibly suggestions for an ADSB unit?

Thanks-

If your Nexus has a new enough version of Android, both of the ADSB In
solutions discussed here on the list should work fine. The two options
I know of are the "$10 ADSB" described on the Apps4Av website, and the
StratuX ADSB In (and much more) receiver.

The "$10" one is probably $30 for a good one these days, and has the
advantage of very light weight and space requirements (basically a thumb
drive). Downsides are that it will probably only be able to run using
the Nexus battery via the OTG USB plug (no wifi or bluetooth option),
probably preventing sending any power available from your E-SLA to the
Nexus. But maybe your flights are short enough for that to be moot?

The StrauX (X emphasized to differentiate it from the StratuS that's
much more expensive and potentially problematic with anything but
ForeFlight and iStuff ( Apple iOS). StratuX works with everything, and
includes an excellent GPS with inexpensive options to also add AHRS and
other goodies. It uses little power; costs about $100-150; can run on
its own battery if installed; connects via wifi; and can be permanently
installed, easily removable, or completely portable to use at home on
other flights or anywhere.

If you have the weight, space and cash required, I'd go with the
StratuX. That said, I also carry a "$10" unit in my flight bag for
backup. Both work quite well, and I like having the advantages of each.

I think you are mixing up ADS-B IN with ADS-B OUT, Avare has nothing to do with ADS-B out.

There is no requirement to have ADS-B IN anywhere, it was used as the proverbial carrot on a stick to entice GA to equip with ADS-B OUT.

Avare will take advantage of ADS-B In provided your IN device is using GDL-90, be forewarned that there are devices out there that are only compatible with foreflight, these will not work with Avare.

I would suggest you start here as it will tell you what you need for your flying:
 
https://www.aopa.org/go-fly/aircraft-and-ownership/ads-b

I believe E-LSA falls under the experimental rules for equipment, you might want to check with EAA for guidance as to what you can install as the experimental market has some low(er) cost solutions than the certified market has.

Thanks for pointing out the word "requirement" in the question, Jeff.
As for ADSB Out, you presumably know it's wise to have both Out and In.
Especially if you're going into airspace with lots of fast movers.
The question about compatibility w/Avare would be addressed by choosing
an Out unit with no In capability.

The least expensive Out-only options are cheaper than Out & In units,
and having them separate gives a modicum of redundancy along with
potential In portability. The least expensive In-only units tend to be
more broadly compatible, with "$10" and StratuX units topping that list
and both are fully compatible with Avare. The cost of Out-only with
StratuX for In is probably most cost effective, and completely
compatible with Avare and probably all other apps.

Flying where you "need" ADSB means "rule" airspace and ADSB-B out and a transponder.

Avare and many ADSB-In devices are not "needed" and without the system seeing you having "out" you may not have a full traffic picture ever, in any airspace.

If you have an engine powered alternator or generator then you may need a transponder and ADSB-Out in rule airspace.  A mode S transponder like the Appareo Stratus ES/ESG or a UAT and mode C transponder and altitude encoder run about $3k plus installation and sign off test.

It may enhance resale value enough to pursue it, it may also cost enough to land outside rule airspace and use ground transpo.

If a 2 stroke with more lighting coil than true alternator, you might not have the excess amps.  The EAA if not your FSDO might help.

What airports and routes and engine combo with what output electrical power generation do you have?

ADSB-In and Avare are likely easiest fed by a Stratux or dedicated IN.

There are many ways to skin the OUT cat if you need it.  The main gotcha for AVARE is NOT using a device like GARMINs that don't use the generic GDL-90 message sentence structure AVARE reads.
