SkyTrax FAQ's

I had my Archer pre-wired for the MLB100 when my IFD540 was installed in April.  Checking with my avionics shop, my MLB is in, but he indicates it is not STC'd. 

Can anyone from Avidyne confirm this?  I want to make one stop for the 10.x upgrade and MLB install since the shop is not local.

Thanks in advance for any input you have.

I am expecting my IFP440 soon (supposedly this month) to replace my Garmin 430W.  I also have a Garmin GMX200 display and an Aspen Evolution unit.  The question is, can I get an MLB100 or MLX200 to display on any devices besides the Avidyne IPF440? 

I am installing an IFD-540 in my Cessna 172 and at the same time I am installing wire provisions for an MLX200.  The installation part is done and the airplane is mostly closed up, but I just learned something that I didn't know.

I thought that all of the data from the MLX200 would go to the IFD as serial data.

If I am reading this thread correctly, only the weather (FIS-B) data will flow as serial data (at least initially), and the traffic (TIS-B) data must flow over a 429 bus.

So the problem is that I did not provision 429 wiring, since I thought it would all be on the single serial data port.  It's my mistake, and if it means I have to wait for the traffic data until a future software release, then I am okay with that.

Please tell me that Avidyne at least intends to process all of the data through the serial port at some point?  I understand waiting, and I don't have a problem with that.

Orest Said: "It is my understanding that you need an A&P (although not necessarily an avionics shop) for a sign off. I'm lucky, my shop is right on the field. They slip over to my hanger and do the work so I don't have to worry about it."

Not sure how the A&P would work, but if it is an installation via STC it needs to have a 337 filed and that can be done by a mechanic who holds an IA.

Well, my early bird MLB100 is installed/configured, but here's a NEWS FLASH!

The one exception might be to feed 605A traffic to one device, say the 540, and then for some reason to feed ADS-B (TIS-B) only traffic from the MLB100 to the ASPEN, for example. That would be kind of an odd ball setup. * Orest

That oddball setup would not be good.  The ADS-B transponder tells the ground stations what ADS-B in capabilities you have.  The choices are none, 1090, UAT, and both.  Both means that traffic information can be received on either frequency, not that it must be received on both frequencies.  So at least one of the ADS-B receivers would not see all traffic.

In this scenario, when the TAS-A is operational, the MLB100 will serve as a ADS-B source for Wx, displayed on the 540.

No experimental here.  Confirmed by phone, MLB (x2) in his hands.  My installer is high volume Avidyne, and a squeaky wheel too.

I didn't realize the MLB100 was shipping.  Thought that was on hold pending 10.1.0.0 software cert?  

MLB100 received today for (pre-wired) install!

May, 2015 is almost over.  Sure wish these deadlines meant something.

The MLX200 looks like the ADSB- in/out solution for my IFD540 KT76A, since I don't fly in the flight levels. Have any idea of the availability and price?

OK, thanks.  I think your chart is confusing on that point as it says "Requires External GPS" for the MLB100 which I interpreted as needing to connect to one.

Interesting. I wasn't aware ADS-B In required a GPS.  Is that RS-232 or Arinc 429?

Simpson,

What concerns me about the chart there is MLX products list a RS232 & A429 Display port. I assume this is in reference to FIS-B data only?

As I understand it the MLB-100 uses A429 for the traffic information (TIS-B) and RS232 for FIS-B data.

Maybe I'm missing something obvious when I look a the table (i.e. Is display port some odd protocol I've never heard of?).  Either way that table could be cleared up a bit.
