Simpson,

Dual band receivers (such as my GDL 39; these now sell new for $700) allows me to receive air to air traffic broadcast from any aircraft with ADS-B Out (978 or 1090 ES).

I noticed on my recent Tucson trip that there are times, even at 12,500', where I am out of range of a ground station, therefore I get no traffic info. from ATC even though I am talking to them on flight following and I am on an assigned squawk code in radar contact. Radar does not equal ADS-B Broadcast capability.

In those times a dual band receiver is valuable as I will get traffic info. from all ADS-B Out equipped aircraft.

Right now I would guess that most aircraft with ADS-B Out are using 1090 ES (like the Garmin 330 and AXP 340).

We would miss all that traffic.

Yes, Avidyne's active traffic system is a solution, but it's roughly $15k installed.

If Garmin can build and sell a GDL 39 for $700 with dual band in Avidyne should be able to get it done, with the ability to interface to panel displays (IFD 540) for under $3k.

Regards, Jim

Thank you for the reply.  I think there is enough evidence on this thread that you can't check the "ADS-B In" box until you have dual-band. I suppose there is a thread over in the 340 thread demanding a remote transponder but that seems more a feature than a basic function. 

You've left a hole in your product line so I sincerely hope you'll work with other mfgs to allow them to provide dual-band solutions to the 540 in the meantime.

It is in standard industry traffic data format, available on both a rs232 and 429 data line. It does not suffer from the TIS-B fragmented standards. One additional benefit to the TAS6xx units. * Orest

jblodgett wrote: The IFD-540 is supposed to be a 100% compatible replacement for the GNS-530.  That means that it should display traffic from a GDL-88 which can use a 530 as the display.  Can you confirm that?

Respectfully, I believe that you need to listen to your customers about this.  I believe that a dual-band receive only ADS-B solution is what the majority of Avidyne IFD-540 owners will want and will wait for.  Word is getting out about the limitations of the single frequency receivers and given the high cost of installed ADS-B solutions I would expect that you will find limited market for them.  I would like to see you move getting a dual band receiver certified higher up on your priority list.

Thanks,
Jim

Well, the good thing is that Avidyne is at Sun-n-Fun and will be able to look around.  It isn't hard to see where the market is heading in this area.

brou0040 wrote: My understanding from Avidyne's ADS-B material is that with a dual band ADS-B solution, you won't see non-ADS-B equipped aircraft via TIS-B or ADS-R when near a ground station (slides 18 and 19) from http://www.avidyne.com/publications/guides/ADS-B-Overview.pdf.  Unless you are in somebody else's non-dual puck, it's showing that you don't qualify for TIS-B or ADS-R, so how would you see non-ADS-B aircraft?  Is this up to date and correct? How do they know if you have a dual in receiver?  If it's portable I'm sure it wouldn't matter, but if you have a certified unit, could you be required to somehow make that distinction via the installation instructions?

Paul wrote: I think the slides are correct.  If an aircraft has dual-band ADS-B in the ground stations won't send ADS-R to it because it will receive all aircraft directly.  However they will send TIS-B, which is the information about aircraft which do not have ADS-B out.  So the aircraft will have all the known information about nearby traffic.

brou0040 wrote: Slide 19 says "To be a TIS-B client an aircraft must: .... • ADS-B In on only one link"  This is what I think is wrong.

I'd missed that.  I agree, that sounds wrong.  If you have ADS-B In on both frequencies the TIS-B will be sent to you on the UAT frequency.

I don't know anything about the stratus, but I'd hope that it can sort it out because if you left your setup as both in and anybody else is in your puck that is 978 in only, you'll have the same problem.

This just landed on my inbox

Does anybody have insight into how ADS-B and the military aircraft in MOAs or restricted areas will work?  What I think I'm understanding is that they are 1090.  Do they have a requirement to transmit while in the MOA's, I assume they are governed by a different set of regulations than GA.  If that's the case, that would seal the deal for me going dual in due to the high speed low level flights around here.
