BTW, the new AXP340 ADS-B Out STC is SA00352BO. It includes an AML. I don't see this up on the Avidyne web site yet (at least not under AXP340 download section). It would be good to also have the ICA (AVAXP-006) and AFMS (600-00309-000) posted to the download section since these are part of the STC approval.

Simpson?

Agreed, we are going to post all the documents this week. Once they're up, I'll send the link over.

Great news!  Congratulations.

Now, if I can just get the rest of my avionics working, I can finally start flying this stuff.

Hi Simpson,

Any updates yet on getting the AXP340 docs (STC, AML, AFMS, ICA) posted? We sort of expected this by the end of last week....

I don't think it works that way.  If your transponder says you can receive on both frequencies then the ground radar can send you the data on whichever frequency it prefers.

Interesting perspective, but are you certain of the above, or just speculating?

It would seem more logical that if set to both, the system should assume an ADS-B IN reply is required on both. If not, then there would be no way to activate reception on both a portable UAT and panel mount 1090ES (like the upcoming TAS60xA units)

* Orest


I asked the Eastern Region, NextGen Branch of the FAA about this and they gave me some answers.  Retransmitting from UAT to 1090 or vice-versa is ADS-R.  Transmitting information from radar for a plane which does not have ADS-B out is TIS-B.

Here's the important info:
  • The ground stations assume that if an aircraft announces it has ADS-B in on a frequency it will hear all aircraft on that frequency directly.  So they never send an ADS-R rebroadcast on the same frequency as the aircraft sent it.

  • If an aircraft announces that it has ADS-B in on both frequencies the ground stations will not retransmit any aircraft.
  • If an aircraft announces that it has ADS-B In on both frequencies then TIS-B will be sent on UAT only.
So there is no way to activate traffic reception on a panel mount 1090 receiver and a portable UAT transceiver.  If you have two independent ADS-B in traffic systems, one on each frequency, at least one of them will not see all traffic.

If that is indeed the way it will roll out, it largely eliminates the traffic "carrot" altogether for most installations.

Most portable ADS-B In receivers sold now are dual-band.  If the installed ADS-B In receiver is single-band then the ADS-B Out device can announce that it has ADS-B in on only that band.  Both receivers will then see all traffic.

If someone has a portable single band receiver they might want to sell it and buy a dual band unit.  Compared to the cost of the certificated UAT or TAWS receiver the portable isn't expensive.

My avionics shop was going to have no problems activating the ADS-B portions but the day before they finished the install, the STC came through.
