Question for the garmin 430W guys

[rfazio1951]

I’ve got a SV1000 system in my plane, and an Arinc 429 between the Garmin 430W and the Skyview. The system works great. One point I’m seeming to have trouble with, is that when I choose a bearing on the skyview, and select the 430 I don’t get a signal. I could swear I was able to do it before, and I’m thinking I’m doing something wrong. I select a bearing #2 as my NAV 2000 and it works perfect. I see a bearing on the HSI to the VOR that I selected. But when I tune the same VOR on the 430 as bearing #1 nothing. So, now I’ve checked and swapped antennas, tuned in VORs to navigate to, and selected ILS approaches. That all works perfectly on the 430. I just can’t get a bearing, which I use to check the two units against each other. Anyone know what I’m doing wrong?

Is your 430 out of GPS mode (as controlled through the CDI switch)? Do you have the 430 selected as bearing 1 and as HSI source? The HSI needle should change to green color if set to a VOR.

 

[rfazio1951]

Yes the 430 is out of GPS mode. I have the 430 selected as bearing 1 mode. I don’t think it matters what you have selected as the HSI source. But yes I have tried it both ways.

This is going to sound really stupid, but...if you're using the same VOR, is one Bearing indicator covering the other one and hiding it?

 

[rfazio1951]

I thought of that, but no. You can tell the difference. One has one feather or what ever the arrow like lines are. Bearing two has two feathers. If they are on top of each other perfectly you will see three feathers. I also can shut off the second bearing and see nothing. Sometimes with the HSI on and close to the same bearing it is hard to tell though.

 

[skysailor]

Just a thought. With the system fully up, turn off the 430. Then power the 430 back up with the HSI source set to the 430. As the unit goes through self test as part of the boot process you should see the CDI move left and right as well as the glideslope moving up and down. The other idea is to check you are getting good data out of the ARINC module. Tech support would be the source here.

I’m getting info from the arinc 429 and 430. I do get info to the HSI if I put in an ILS approach for example. I get the horizontal on the HSI and the glideslope. It’s only when I’m trying to get a bearing that I’m having trouble. Only a bearing when using the PFD menu and selecting a bearing on the 430. I get a bearing on the NAV2000 no problem. Does the bearing use the arinc? Or is it on serial wires direct to the skyview? Could I have a bad connection?

Bearing information comes over ARINC, so it's not a physical connection issue. When you cycle through your bearings, what does it cycle through?

 

[rfazio1951]

Ok, I have the Garmin 430 connected and a Nav2000. When I cycle through the bearing options it start with Skyview, then comes the Garmin 430, and there are two bearings from the 430. One is GPS I guess, and the second is the VOR. The fourth choice is the NAV 2000. there are also two from the NAV 2000. Then nothing and back to the skyview.

do you mean that as you cycle BRG1 you see
Skyview
GNS430
GNS430
NAV2000
NAV2000

in that order?

 

[rfazio1951]

YES

And when I do, it I get a bearing on the first NAV 2000 not the second, but nothing on the 430 neither the first or second. This, when I have a vor tuned in on both the 430 & the NAV, and the 430 is on VLOC not GPS, and the frequency is selected as primary, not secondary.

Trying to be clear not nasty or anything. I’m pretty sure i’m doing something wrong, as that is how most of my problems turn out. I always think something is wrong or not working properly and it’s always me. But I’m learning.

 

[swatson999]

No worries...I know you're just trying to be clear...so am I.

Have you verified that the 430W settings are as per the installation manual, for both the Main ARINC page AND the VOR/LOC/GS ARINC page?

Have you verified the Skyview settings are as per the installation manual, for the ARINC 429 page?

 

[rfazio1951]

Yes, but I will be at the airport tomorrow, and will recheck the settings.

 

[Dynon]

And just to be clear - you won't expect a bearing when tuned to a localizer. You'd only expect one when you're tuned to a valid VOR signal.

 

[rfazio1951]

Ok, that’s what I’m trying. Like I said I’m seeing a bearing with the NAV unit. So I know the VOR is on line and working.

 

[rfazio1951]

I went out to the airport today and checked the settings. Both the 430 and the skyview match the settings in the installation manual perfectly. I was actually hoping to find something wrong.
