Hi all,

 

Hoping someone can help. I am rebuilding an old B206 simulator under FSXSE as a favour for a friend who doesn't want to change to XPlane or MSFS2020.  

I have Panel Builder, FSXSE and RealityXP GTN750 on the same computer, and it's all running surprisingly well.

However, I am seeing some odd - and 100% repeatable - behaviour with the GTN750 and the HSI. 

When the SIM starts, the HSI GS NAV indicators are red, and the needle shows no left/right deviation.

I press the first Continue button on the GTN750, the HSI does not change.

I set the active NAV to a local VOR, and press the "Installed Databases" Continue button. The HSI course needle immediately turns to point to the VOR, the needle splits to show left of track, and the GS and NAV turn grey. So far so good.

But the instant I press the "All map and terrain data" Continue button, the GS and NAV indicators on the HSI turn red again, and the needle "unsplits". After that there is nothing I can do to reconnect them.

As you can tell from my description, I'm not an IFR pilot, but I'm sure this isn't correct behaviour. I've tried the following in the RealityXP.GTN.ini file in my aircraft folder:

LinkCrs = true

LinkHsi = true

LinkObs = true

LinkVor = true

But I can't see any obvious changes in behaviour. Ultimately, I will be connecting an Elite HDG/CRS panel (and others) to this computer, but that shouldn't make a difference, should it?

Any advice would be hugely appreciated, I am just about start tearing my hair out, and I don't have that much left...

Many thanks in advance

Chris

 

Hi,

I'm not sure to understand what you mean with "unsplit" but depending on the aircraft you're using, you might need either or both LinkHsi and LinkVor as a minimum. Please note the GTN device must also be set as "Master Device" and in GPS mode, and the simulator own NAV/GPS switch much also be in GPS mode. There is a GTN setting allowing you to configure the CDI synchronization mode between SIM and GPS.
