Skyview / GNS 430W question

[Jrskygod]

In doing GPS approaches using the 430W. I get the course displayed on the Dynon Skyview map screen perfectly. However when shooting an approach with a hold or procedure turn, the hold or procedure turn does not display on the map. It shows the course to the hold and after the hold but no hold? Also when in VOR or LOC/ILS mode I do not get distance/dme displayed like I do with a LNAV approach. Am I doing something wrong? Am I not displaying something properly? Have I configured my system incorrectly?

For the hold procedures: check your 430's ARINC output. Is it set to to GAMA 429 or GAMA 429 GRAPHICS? GAMA 429 GRAPHICS is correct.

The NAV side of the 430 does not provide distance.  With radios that provide a decoded ident for VORs we can provide virtual DME information, but unfortunately that info doesn't come from the 430 (or other ARINC devices).

I had understood curved flight paths from the GNS-430W were not yet supported in Skyview (as contrasted with the GTN units). Has this changed? (Or was my understanding incorrect?) I've also never seen holds on the Skyview.

Sure enough. Changing GAMA 429 to GAMA GRAPHICS 429 did the trick. Holds and other curved flight plans are now displayed. Duh.

There is a second selection, GAMA 429 Graphics w/Int.
Does anyone know if that is valid for Skyview and how does it differs from the GAMA 429 Graphics.

 

[Jrskygod]

Just got back from the airport. I changed the configuration to GAMA 429 Graphics and presto I have a hold now displayed. I wanted to fly, but it started raining, so tomorrow I'll see how it works out. I also was reading about the GAMA graphics w/int and trying to figure the differences. Sure wished the install manual had this information, I would have changed a long time ago.

Next problem is to figure out how to get a DME when on an ILS or VOR approach.

 

[dynonsupport]

You will not get a DME when using the ILS or VOR from a 430. It doesn't have DME.

You are allowed to use GPS as a DME, but you have to program the GPS to the waypoint you are using. It doesn't know you've tuned the AAA VOR, you have to tell it.

This doesn't have anything to do with SkyView. Read up on the 430 some more and how to use GPS overlays and loading procedures on it so it gives you the info you want.

I'd recommend updating the Skyview install manual. Page 12-7 of Revision W says to use "GAMA 429" which is probably why all of us 430 owners were missing holds, until now.

I was *thinking* that I had set mine to GAMA 429 and didn't recall anything about "Graphics"...intended to check this next time at the hangar.

Yes, this would have been good information to know...how long has this been available and we didn't know it?

 

[Dynon]

Apologies - we indeed missed that detail in the documentation. We've got it in the system to address with our next manual revision.

Dynon, is GAMA 429 Graphics an option for the GNS 480?

 

[jakej]

Someone else who has got the correct settings may chime in here but the 480 should not need GAMA 429 Graphics (like the 430/530) as it will do the procedures like 'Holds' in it's own right. That took a while for Garmin the get it into their own developed products, the 480 lead the field, & some say still do, for a long time

I think he's talking about *outputting* GAMA 429 to the SV so SV displays it...?

And to second the other question above...what is GAMA 429 Graphics w/ Int?

 

[jakej]

I'll find out soon enough, am about to wire up a new 480 (still in original box) & will try various settings if no one comes back with an answer

 

[skysailor]

Thanks Jake. My 480 does fly all the holds and procedures but I am not sure they display on the Skyview map. Let me know what you find out. I'll get back here if I get to fly the Glasair in the next few days. I will check my display.

 

[Jrskygod]

I confirmed the GNC 430W GAMA 429 Graphics does display the holds/procedures. The skyview will fly them (always has) but it sure is nice to see the little plane following the box now. And to third the other question above...what is GAMA 429 Graphics w/ Int would it work with the 430 and give us additional information? I'm still trying to get a DME reading. I know the 430 has the information, the problem is can it tell Skyview haw to display it.

 

[Dynon]

According to the 430's installation manual (look around on the web for it - it's easy to find), GAMA 429 Graphics w/ Int is basically the same as GAMA 429 Graphics but supports a couple of particular Sandel HSIs. SkyView does not have a way to display DME information from a 430. It doesn't have an actual DME receiver, and it doesn't communicate tuned VOR identifiers in a way that will let us employ our "virtual DME" GPS distance feature (which is essentially the same number that the 430 itself will give you).

 

[Jrskygod]

It would be nice if the second needle could have a larger data box and then you could use the skyview or another reciever to display direction as well as distance to that waypoint. The gps in the 430 knows how far it is to a selected waypoint. Too bad it wont send that data out at the same time when on VLOC.

 

[dynonsupport]

If you're relying on GPS anyway for your DME, why not use a GPS overlay instead of VLOC?

 

[GalinHdz]

For the hold procedures: check your 430's ARINC output. Is it set to to GAMA 429 or GAMA 429 GRAPHICS? GAMA 429 GRAPHICS is correct.

What is the difference between GAMA 429 GRAPHICS and GAMA 429 W GRP -H?
