SkyGuardTWX Vision-Pro

Anyone else using the SkyGuardTWX Vision-Pro system with their iFly 740? I'm seeing an issue where the SkyGuard loses GPS lock. The iFly is set to default to the Skyguard sigal. If I shut the Skyguard down, the iFly built in GPS takes over and navigation is restored. If I power the Swkyguard back up, sometimes it regains lock and sometimes not. The problem has been pretty random thus far.

I've checked the antenna connections and they are good. Both the Skygruard and iFly external antenna sit side-by-side in the top of the windshield.

Ought to be flying instead of posting.

Re: SkyGuardTWX Vision-Pro

That sounds more like a Skyguard issue than an iFly issue. If iFly is connected to an ADSB-in receiver, it will always preferentially use the GPS from the ADSB device...even if the GPS solution there is poor. iFly only uses the internal GPS of the iFly device or tablet it's running on if no external ADSB-in device is connected.

Sounds like the GPS subsystem in the Skyguard is not operating properly, and that's the problem that needs to be addressed.
