Dynon Previews Integrated IFR GPS Navigation Capability for SkyView HDX
Next-generation capability is in development to bring full IFR GPS navigation, including coupled LPV approaches, directly to the SkyView HDX platform with zero additional panel space required. Dynon is excited to announce the development of a revolutionary leap forward for the light general...

I'm quite excited about this to be honest, because I don't want to cut into my panel if I don't have to, and knowing Dynon, it should seamlessly integrate with everything. I've been holding out for GPS 175 to go with my Dynon set up, but now I think the plan is to wait for this!

Dynon Preflight Brief

Dynon Preflight Brief
Don’t know enough to make a fully informed opinion, but is a “revised” HDX similar to putting wallpaper over the wall? Could Garmin have introduced some new modules to revise the G3X, and call it integrated? It would seem that Garmin started with more of a blank slate, to derive AXIS as an integrated system. Will this new AXIS press Dynon back to the drawing board quicker than Dynon had expected? Thinking out loud here…
I’d say so. HDX is great from the network perspective, apt-com etc. synthetic viz isn’t smooth at all, toga button doesn’t bring up the FD to ROL-TO, can’t put a crossing alt on a waypoint in the flight plan.
I would think that Dynon had better be hiring serious hot dog AI programmers and AI computer architecture professionals to up the ante on Garmin. Whole new -- Next Generation Fully Integrated AI Enabled Panel. Makes flying easy and safe. Makes IMC easy. Maybe too easy...?? I guess we'll see...

I really like the HDX I'm installing. Pretty simple wiring, intuitive to use, and the button shelf will be nice to stabilize the hand in turbulence. But I do agree it looks unfinished.
From an install standpoint, super easy. Buttons are nice to hang onto that lip if needed
I agree, they get a C+ for estetics, but an A+ for functionality. When you are in the soup bouncing around, the functionality sure is nice.
The functionality is mostly pretty nice. There are some functions in the software that would be really nice to have. For example, both AFS (Dynon owned) and Garmin overlay the localizer and glideslope on the attitude indicator, so you don't need to scan down at the HSI to fly an approach. Another issue: there is no secondary HSI needle, only bearing pointers. It would be really nice to have, for identifying a crossing fix with VOR's; I know, old school, but GPS jamming is real. From a panel build perspective, Dynon don't have a true G5/GI-275/GRT-Mini competitor. The D30 is fully standalone and larger than those devices. It would be nice if they did, or like AFS, supported the use of G5 as a third ADHARS source. My last complaint is flight-plan cross fill to standalone IFR navigators-doesn't exist, even for the Avidyne products. Avidyne says they are happy to do it, but its over to Dynon to write the software.
My final note of the day: if you lose your pitch servo for some reason (it is no longer identifiable on the skyview bus), you're flight director also disappears. Fortunately I discovered this during day, clear and a million VMC ops. Wouldn't be fun in IMC.
That being said, the customer service is prompt, the nav updates are free, out of warranty repair costs are much more reasonable than big G, and they have a trade-in program for the classic to the HDX, which Garmin do not for the G3X Touch to AXIS upgrade. Since I'm already in their ecosystem, I am considering this IFR module, depending on price and database subscription. If it will run on the backup battery for the displays, that buys a pretty darn good bit of redundancy.

Agreed that would be nice to have.
That right there is the HDX's greatest weakness in my view. I really like the way GRT does it with their "needles" depiction of the localizer and glideslope. I like it so much I'm in the process of adding a GRT Sport EX to my already very nice panel just for that feature.
Same here. Well see where they come in on price. Would be hard to justify given I already have a GTN xi.
Can you please list some of the functionality that exist that Garmin doesn't have or is not as good.
I am not as familiar with newer generation of Dynon but I have flown behind AFS and it lacks many of the functionalities.
- For a simple navigation, you will need to have an active needle much in the way that ILS works. In Garmin your heading could be south and if you selection a destination to the North, I will turn you around automatically and captures that waypoint.
- Smart Glid
- VNAV
- Logic settings for sensors
And the whole ACM is single point of failure for all your electrically operated devices if one is using that.
