Biggest thing, though, is that it would permit integration with some of the other complex panels...for example lots of folks are looking for an FMS that Eaglesoft could integrate into its Citation X...such an interface might make a collaboration with them possible that'd sell more of both the C-X and your gauge package.
You lost me here. I use ISG1 it in my ESDG Citation X all the time, (by replacing the ES MFD with the ISG1 MFD) we even created a template for it that's available on the template page.
What are we missing that currently prevents others from this integration ?
Likewise, if I could integrate it into the freeware TinMouse II (I'm the gauge programmer) there'd be people interested in buying the ISG FMS just to have in our 737-200 I think.
The freeware CIVA INS, and the Reality XP GNS units both have good (but really different) interfaces and I've been able to integrate them properly with the TinMouse II HSI gauge to show CDI and distance-to-waypoint data based on the RNAV data.
Sorry if I'm not understanding.
But why wouldn't you just replace/retrofit the Tinmouse HSI with the ISG1 EHSI ?
You would then get the CDI distance-to-waypoint info from the ISG1 EHSI/FMS.
