Adding or interfacing external ADSB IN device (not out) to a G1000 MFD

[Healthpilot]

I do have ADSB out in my G1000 configuration. I am using my iPad now to get ADSB IN (traffic and weather) but it'd be nice to have it integrated on the G1000 MFD.

What are my options to do this?

As an example, I have seen this setup below (on FB not mine) and I was not aware that I could interface a Garmin GDL 50 to a G1000 MFD. What type of cable accessory is needed to do this?

What transponder are you running?

There is probably a Garmin box that connects to the G1000 that does both in and out… in case there isn’t IO room to add another box…

 

Review the GDL boxes that Garmin has… expect to find a remote mounted box that does what you want…

Some GDL remote mounted boxes include, in, out and act as a WAAS source…

 

If you use a Garmin resource to update your software… they make a great resource for updating hardware as well… 
 

PP thoughts only, not a Garmin guy…

Best regards,

The GTX-345R transponder should deliver weather and traffic to the G1000 MFD.

You can't. They are using that to supply adsb-in on to their tablet

I thought so too. However if you look at the MFD it looks like it gets ADSB traffic data. Maybe that's from another (separate?) internal G1000 transponder though. 

That configuration must be A LOT more expensive I am sure.

The GTX345R will definitely get you ADSB in..   Older GTX33& 33ES transponders will display TIS-A traffic from the mode S radars that are configured to send TIS-A. 

All G1000 systems have had that capability.   You would have to zoom in and see if the flight ID or speed shows up in the traffic display to know if that display is ASDB or just the original TIS.  It could also be a L3-Skywatch TCAS.  you can't really tell without looking at the LRU list. 

When the GTX345R is installed you loose TIS-A but replace it with the TIS-B and TIS-R traffic.

You can't take an uncertified portable (GDL 50, 51, 52) and display information from it on a certified panel unit (G1000).

If you see traffic displayed on a G1000, as Paul mentions, it's either (1) TIS-A (or originally just called TIS*) from the original GTX33 Mode S transponder, (2) TCAS Active Traffic from Skywatch 497 or Garmin Active Traffic or (3) they are getting TIS-B from a newly installed GTX-345 transponder and they have the updated G1000 software to make that possible.

I need to check but in my config. I have ADSB out and I have a 33 series transponder. I do have and see TIS-A traffic no problem. In your opinion is it worth considering an upgrade (I doubt it)? This is the Mooney SB btw... I was hoping to find another Garmin product to interface without replacing the transponder. Not feasible I guess.

I love my 345R with GPS. Could not imagine being without it.

If you don't have WAAS and you decide on the GTX345R, which is a great transponder, you'll need the one with the internal GPS, which means another GPS antenna. But once it's in i think you'll be pleased. Everyone sells their airplane someday. If you don't have ADSB-in there will be a reduction in what people pay. So in effect you'll pay for it someday anyway, if it's possible might as well do it while you own it to enjoy the benefits.

You could add a GDL88, but that costs almost as much as the GTX345R.   Since you have the GTX33ES and you must have WAAS GIA63W's to be ADSB compliant, I would upgrade to the GTX345R (or RD if you are going flying in Canada) and your avionics shop should be able to sell your GTX33ES.   

My ADSB-IN is down right now due to a technical glitch, and I miss the awareness that being on PFD/MFD provides.. the ipad just isn't the same.   I felt that paying the extra $$ for the 345R was worth it for ADSB compliance rather than upgrading the GTX33 to ES.   I had the option for both, I just wish now that they had the GTX345RD at the time, since it looks like the future outside of the US will be satellite ADSB and therefore need two antennas.

Seconded.

I would strongly consider retiring/selling the GTX33 and putting it against a GTX345R installation.

I already have WAAS so that's not a benefit to me. I still have to do the math but it's at least a $6k to $8k investment net after trading in/re-selling the GTX33 installed. For now I think that I will upgrade my iPad and get ADSB and weather on that one. That's a $1k investment max. Not integrated but also good for redundancy.

Great - the WAAS is the expensive upgrade! This is only about 20% of what WAAG would go for today.
