New MLB100 978 MHz ADS-B In Receiver

scott wrote: I am planning a 540/440/340/MLB100 install next month. I currently have a GDL69 and I was told today by my shop that the GDL69 with the Pro subscription will deliver more information such as TFRs and higher resolution nexrad than the free wx info than you get with the MLB100. Is that true? I was also told that I could keep the GDL69 and display weather from that but get traffic from the MLB100. Anyone know if it is possible to split the source of weather and traffic like that?

The list of weather products supported can be found here:  http://www.avidyne.com/products/ifd540/ifd-weather.asp and then compare that to the table of supported MLB100 products in the pilot guide on page 3-27.  (BTW, I'll update the webpage comparison to add MLB100 shortly)



And here are some relevant snippets from the pilot guide:

NOTE
ADS-B US Weather Radar Data is Coarse

When compared to subscription Datalink service
data and even ADS-B Regional data, the CONUS
weather radar data appears as a noticeably coarser
depiction – this is a function of the supplied data.


NOTE
Weather Source Selection

An individual IFD can only display ADS-B (e.g.
“MLB100”) or Sirius/XM (e.g. “GDL-69”, “MLB700”,
etc) weather at any given time. The choice to select
the source is made at time of installation in the
setup pages.


TIPS AND TECHNIQUES
Weather Overlays in Dual IFD Operations

For those installations with dual IFDs and more than
one type of weather source (e.g. GDL-69 and a
MLB100) in the aircraft, Avidyne recommends wiring
one weather source to one IFD and the other
weather source to the second IFD

TIPS AND TECHNIQUES
Weather Overlays in Single IFD Operations

For those installations with a single IFD and more
than one type of weather source (e.g. GDL-69 and a
MLB100) in the aircraft, Avidyne recommends wiring
both weather sources to the IFD so that the higher
priority weather overlay can display on the IFD and
the lower priority weather data can be streamed out
of the IFD via WiFi for display on a compatible
tablet/wireless device application.
The current display priority is GDL-69, MLB700,
AV300/350, MLB100.


NOTE  Dissimilar Weather & Traffic Source Data Not  Shared

Dissimilar weather data sources (e.g. GDL-69 data
on one IFD and MLB100 data on the other IFD) will
not be shared between IFDs. Each IFD will display
its own weather data in this case.
Likewise, dissimilar traffic data sources (e.g.
TAS600 data on one IFD and MLB100 data on the
other IFD) will not be shared between IFDs. Each
IFD will display its own traffic data in this case.

NOTE
Traffic Source Selection

An individual IFD can only display ADS-B (e.g.
“MLB100”) or sensor traffic (e.g. “TAS600”,
“Skywatch”, etc) traffic at any given time. The choice
to select the source is made at time of installation in
the setup pages.

MLB100.

I am planning a 540/440/340/MLB100 install next month. I currently have a GDL69 and I was told today by my shop that the GDL69 with the Pro subscription will deliver more information such as TFRs and higher resolution nexrad than the free wx info than you get with the MLB100.

That's correct. 10.1 adds a new 232 port selection called, "MLB100 Wx".

Any ship date yet?

Aspen ATX100 (G) is already STC'd, using its internal GPS as WAAS position source.

I have two 540s so displaying plates on one and other things on the other is no biggie.

Not sure how much time delay this glitch introduces for the MLB100 Traffic display capability.

No much earlier
I recently did the G 500 upgrade, see my pic in BT
I had the shop pre wire me for the MLB100

I did a factory direct pre buy on my first 540.
Bought the 540/340 package deal from Gulf Coast.
Does that qualify?

Not too excited about the MLB100 or the 340. The 1090out/978 in combo seems incomplete. In fact, I had put my 340 up for sale and am planning on getting the Sandia ADS-B in/out transponder instead. But, if Avidyne sends me an MLB100 then might stick with the 340 for now. Still waiting for my BT keyboards, but I guess that is timed with the 10.1 release.

Me too!

I don't think you are confused.  Your solution sounds correct to me.  If you have an MLB100 you set your ADS-B out to announce only 978 MHz in.  The Stratus will see multiple messages about some planes but it can deal wit that - as was pointed out it already needs to be able to deal with it.

Boy, am I confused.  Currently I have an IFD540 and AXP340.  I also have a Stratus and an iPad.  The AXP340 is set up to indicate that I have 1090/978 in.  So if I get a MLB100 that means I won't receive ADS-B traffic from ground stations that originated from 1090 equipped aircraft because the ground station will assume I am receiving 1090 traffic directly?  So in that circumstance I should change the AXP340 configuration to indicate 978 in only.  That way the ground station will repeat on 978 all 1090 traffic as well as mode-C traffic so that it will be received on the MLB100.  978 traffic will be received directly by the MLB100.  Is that correct?  But that means the Stratus will receive both direct 1090 signals as well as 1090 signals repeated on 978 by the ground station.  Maybe that is not a problem and the Stratus can sort out the multiple returns?  Does all of this sound correct or am I missing something?

OK, so TIS-B and ADS-R are different concepts. Wasn't clear on that before.

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.

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?

Right.  From the Pilot Guide, Install Manual and FAQs:

Plug and Play Details

The IFD is a “plug and play” replacement of the following equipment:

Garmin Product ID	Plug & Play Software Baseline	Comments
530 530W 530AW	4.01 (Main)	No HTAWS enablement.  This corresponds to Rev C of the 190-00357-08 Garmin Install Manual.

The following table represents the complete list of unsupported 530/530W functionality in the IFD:

Unsupported 530 Functionality	Comments
Manual entry of fuel flow	Fuel totalizer data and computed fuel at waypoints/destinations are only supported in installations that integrate a fuel flow system.  In no cases can you manually enter fuel flow in the IFD.
TAWS/HTAWS	TSO C-151b TAWS is a future capability.
Demo Mode	Demo mode is not supported on the IFD.  The accompanying IFD tablet training application should be used as the demo device.

 

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?

If there is great concern about being outside of the coverage area to receive the air to air 1090 from a 978 rebroadcast, we offer the TAS-A. Not only are you going to see Mode A/C/S transponders but you will receive the extremely accurate position from ADS-B if it is available.  Things may evolve out of the "ML" series of ADS-B IN boxes in the future.

Hi David,

Yes, the next big avionics item for me is (probably) an Aspen PFD 1000 Pro to drive my Century III autopilot.

After that I'll save up for a DFC 90 as my trusty C-III won't last forever.

In that hierarchy the active traffic system is a distant 3rd. Still, I'd really enjoy having one as that will provide the most traffic info. (although still not all traffic).

But if I can pick up a dual band receiver and get it installed reasonably that would be worth having.

Regards, Jim

+1 for Bellanca guy Simpson.
