I have played with the HX steering gain but not recently. I'll try some extremes and see what I get. Regarding the various modes: There is 'full function 2 axis HX driven mode' where the TT AP displays "EXT LS GS". I assume that is ARINC driven and it is full GPSS steering mode. There is '...

I have 1,000 hours on this installation of (3) HX systems and a TT AP in an RV10. This problem occurred sporadically in the past and is only noticeable in calm air. Now it's a constant problem in calm air. When HX is driving TT AP it constantly banks left and right. It seems to be hunting for the ex...

The waypoint markers were added to the HX a year or so ago and they are great. What are they called? (I call them 'lolipops') They provide both lateral and vertical guidance to the next waypoint on a flight plan. What else can you tell me about how they work? Is there any point at which they are not...

I have disco'd the clock power lines and taken a few flights. Didn't miss it a bit. All is fine now. Having (3) HXs installed, and therefore 3 clock power lines, I think the draw was just too much for my battery. I've flown over 150hours each of the last 2 years but my flights are often 3-4 weeks ap...

Thank you Katie! Exactly what I needed to know. Since normal ops depend on the G430 GPS, I'm thinking that I won't even notice the search time. I will be discoing the line to all 3 ASAP... am hoping that I have them fused separately so that popping a fuse is all that will be required. Thanks. Bill

My (3) HX panel is wire so that 'clock power' is supplied 24/7. Originally, as I recall, it was required if the systems clock was to retain the time of day. Recently, went I had left clock power disconnected, it seemed that the system retained the correct time, or at least picked it up from the GPS ...

I don't recommend replacing IAS with TAS in the airspeed tape either (actually, you can't do it anyway) for the same reason Bob wrote. TAS can be displayed on the PFD, however. In the Horizon, go to Primary Flight Display page in the Set Menu. You can configure one of the data fields to show TAS. I...
