PA28 Turbo Arrow III/IV coupler radio selector broken
-
Hello,
Following your tutorial for this plane, I have set the Nav frequencies in Nav1, and Nav2, when arriving at the first VOR, I want the AP to follow the Nav2 frequency, so based on the tutorial, by selecting on the cuople radio selector from Nav1 to Nav2 it should do it. Well it doesn't. When I try to move the Switch down from Nav1, the switch just snaps back up. So I can put only Nav1 or Off position.
I have video showcasing this, but I can't upload it. Not enough privileges.
Anyway, is there something Im doing wrong? or is this part of the plane broken?

Hello, forgot to mention.. MSFS2024. I have submitting a ticket requesting some help as well.. But if you know something I don't, please let me know. Its kinda hard using just one nav. (not impossible, just makes it more annoying) :)

Thanks for confirming. I've moved this thread over to the MSFS section of the forum just so it doesn't get lost.
I've just tested this on my side, and the Coupler Radio Selector Switch is working as intended. Note that the position of the switch will only dictate which Nav radio the autopilot is coupled to, it won't affect which Nav radio is supplying data to the HSI.
In the following screenshot, NAV1 will always supply data to the instruments highlighted in blue, and NAV2 will always supply data to instruments highlighted in red, regardless of the position of the Coupler Radio Selector Switch.
Hope that helps.

I can confirm, I have the same issue, I can't switch to Nav2, it always instantly switched back to Nav1. The behaviour of the switch is correct when I use the PMS50 GPS, but not with one of the standard options.

@Mark I understand that the (in your screenshot) Nav2 will indicate the frequency I have set in Nav2 radio, and the "blue" ones the Nav1 radios, the CDI will show the deviation over that nav1 radial.
The problem is that the couple switch is not visible in your screenshot, is lower behind the yoke, If I have set Nav1 to X frequency and Nav2 to Y, based on your screenshot, I can set the AP to capture and follow that Nav1, and at any given point I need to start following Nav2, based on my understanding, and following your tutorial, in the couple selector I can switch down to the Nav2 position, and the AP should start following Nav2. The problem is that the switch when I try to put it in the lower position where Nav2 is written, it simply snaps back up, so the AP will never engage on Nav2, how is this working as intended? what am I missing? I have tried doing this using the G480 as well as normal radios configuration.. happens the same.
how could I provide a video showcasing this? I don't have rights to upload.

@Mark Hi,
I have tried again, and as @Astrogator mentioned, using the GPS 100 it seems the switch stays in position Nav2 without issues. Problem is when using GPS: WT GNS Dual or GPS: WT GNS 530. In these cases the switch snaps back to the Nav1/off position.
I can see from your screenshot, that you are using the GPS 100 option, maybe thats why seems correct to you. Can you try the other navigation options and confirm? Maybe we have discovered a bug? -
With it only occurring with the GNS430/530 GPS fitted (and working correctly with the GPS100 fitted), we believe that it is a limitation of the Working Title GNS430/530.
When we implement the GNS430/530 GPSs into our aircraft, we have to select which GPS is used for the NAV1 radios and which GPS is used for the NAV2 radios. The GPSs are then hardcoded to those radios. For example, it's not possible for us to have both "GNS530 only" and "GNS430 only" GPS options, as in one of those configurations, the only available GPS would be NAV1, and in the other configuration, the only available GPS would be NAV2. I believe this is the same limitation as is being reported in this thread with the Coupler Radio Selector Switch.
We have logged this as something to investigate further ahead of the next update for the PA28s, but at the moment, we're not too sure what may be possible.
The tutorial flight in the manual does use the "GPS100" configuration though, so the tutorial flight can be completed with the aircraft in that configuration.

Thanks @Mark for clarifying this.
Hopefully someday you will find the solution. Make a typealias so the WT GNS430 things you have initialised the GPS100 LOL. just kidding.
As as side note, Im really enjoying this plane, and im doing VOR navigation and VOR approaches.. is great plane.. I have to be focus on the flight since there is little AP involved, specially since Im not using the ALT hold virtual feature.Feel proud.
