2020 Requirement?

[cathead]

I have a 430W, a stratus 2, and an old collins transponder. What are my options to meet the 2020 requirement if my transponder dies? What's the best way to use what I have already?

The good news is you have a WAAS position source in the 430W.  To that you can add a mode S transponder that is ES ready: GTX330ES is one option.  There are other mode S transponders that will work, too.  Your Stratus2 will continue to provide you ADS-B IN data -- traffic, weather.  

Or you could add a UAT like the GDL88 and meet the requirements of ADS-B OUT that way.   About the same cost either way.

What is the differnce in the UAT(GDL88) and the transponder? What does it do that the transponder doesn't?

The GDL-88 will display weather and traffic on your 430W. The transponder only sends the "out" signal for ADS-B compliance. The GDL-88 sends the "out" and also receives the "in" (weather and traffic).

If you have a portable solution, like a Stratus or GDL-39, the "out" piece for either will trigger traffic, i.e. full FIS-B on the portable solution.

GDL-88 is only good for the Out option as long as you don't need the ES, meaning you are not flying at FL180 or above...

From Garmin site : 

"the GDL 88 offers an affordable solution to reaching compliance. And even if you fly above 18,000 feet, the GDL 88 can still give you all the benefits of ADS-B “In” data – consider pairing it with a GTX 330/33 ES transponder for a comprehensive ADS-B “In/Out” solution.With ADS-B “Out”, the GDL 88 gathers information about your position, track and ground speed from either your existing WAAS GPS source or an optional built-in WAAS receiver"

Or consider the L3 Lynx all in one box which does it all... More expensive but self contained and very very nice...

May I ask how much the L3 cost install and purchase ?, I'm looking at it...

When I talked to L3, the model I needed ( to fly about FL180 ) was a bit too pricey compared to a  GTX 330/33 ES and GDL88 Combined.

Very nice yes I like it but also expensive I thin in the 7-8amu range.

The basic one was like in the sixes installed, they have some specials for the first 1000 units... Yes, if your plane has a service ceiling above 18k, you need a 1080es transmitter...

I've got a 530W and will be installing a 330ES for the ADSB out. I'll use ForeFlight and the Stratus2 for the in.

Anyone with experience with the GDL88 with a 530W?  I am curious how the weather and traffic displays on the 530.
