Re: GNS430 flight plan not displayed on cross side Hx

Pull the Hx units out of the panel, then work thru the holes on the wiring/connectors, while sitting upright.

Re: GNS430 flight plan not displayed on cross side Hx

I don’t know the answer to your question. But I wonder why you didn’t follow grt’s wiring recommendation, and run the data lines to both Hx units? As it is, if #1 Hx dies completely, you also lose the 430 data on #2. Just splice additional wires to the RS232 line and the ARINC lines out of the 430, ...

Re: Viewing approach plates on HXr

I don’t think gps is required. You’re sure the plates folder has folders for each airport, with approaches inside that folder? Airport folders have three letter/number names, no leading ‘K’? Are you using the memory stick that came from GRT? Some other brands may not work.

End of Support?

It looks like GRT is no longer offering the Hx? Any idea on how long parts and service will be available?

Re: When HX (now HXr) is driving TT AP it constantly wing ro

Agreed, great autopilots. I feel the same way about my Trio, except I need to push 2 buttons after takeoff (Trio has separate engage buttons for roll and pitch); push one stick button to disengage both prior to flare. I don’t see anything like what your display is showing, in the TT digiflight II ma...

Re: When HX (now HXr) is driving TT AP it constantly wing ro

Bill, I can’t find anything on the TT web site about a ‘Programmer’ model. There is a manual for the Digiflight II VS which agrees with my previous post - that you have to push the mode button until displaying ‘GPSS’ to get it to accept external commands. Yours must be a rare model. Perhaps you can ...

Re: When HX (now HXr) is driving TT AP it constantly wing ro

Bill, did you say (and I miss it) exactly what model TT you have? It's been a while since I was behind a TT, but I thought it displayed "GPSS" in the lower left, when being driven by the GRT. I also seem to recall it had to be in altitude hold (my memory may be failing here) to switch corr...

Re: When HX (now HXr) is driving TT AP it constantly wing ro

I’m stumped. One thing you have different from me (beside the TT vs Trio) is the fast trak hub. Is it possible there’s a wiring error, like A and B swapped? I have no idea what that would do. Or, could there be some sort of 1/2 Hz interference being picked up? One last, non-trivial thing to try, wou...

Re: When HX (now HXr) is driving TT AP it constantly wing ro

Did you try Jeff's suggestion? Let the 430 drive the TT; watch the efis carefully. Does the AI or heading indicator (tape) ever "twitch" (even if the plane is rock-solid level)? I'm really curious as what can be going on here.
