Common EFIS Questions

Regarding the new generation products and their backwards compatibility with the existing products...What if someone wants the new system plus a D10A? Or, you have a D180 and want to display engine info on the new screen?

The EFIS-D100, EMS-D120, FlightDEK-D180, EFIS-D10A, and EMS-D10 will all still be for sale for the foreseeable future. We are not canceling any of our currect products. Over time, the D100, D120, and D180 will likely phase out in favor of the next generation system equivalents, which will have all of the same capabilities and much more.

All of our products will be supported for years - with repairs, technical support, and any bug fixes that are needed. There is no way that Dynon would ever stop supporting a past customer. We think one of the reasons we've been successful is that we've tried our best to support all of our customers, and that will continue to be the case. Call us with a question or a repair on a EFIS-D10, a product we haven't sold for over 4 years, and we'll still help with any question or problem you may have.

That being said, we are going to be winding down new feature development on the current series of products after the autopilot is released. After four years, we're reaching the limits of what we're able to do with the computing power in the current products. The major features that our customers have been asking for - such as synthetic vision, moving map, thin screens, etc - are not features that we can implement on our current hardware.

We've also learned a lot with the last generation of products, and to remain competitive we need to take all of that knowledge and translate it into the best avionics we can possibly build. To do this effectivlely and efficiently, we have we have to draw some lines between what we have now and what we'll be building next. For example, making DSAB work between the current and new products would be a huge software effort. If we put our limited resources there, development all of our products would slow down, and we're already a busy bunch over here.


We believe there's an easier way to cross the compatibility border, and that's the offer for trade-in credit on old units. If you are interested in the new system, then we'll take what you have and give you credit towards the next system. It's win-win: you get the new system, a new warranty, and we get to focus on our new product development.

We think that this trade-in program is a type of support that is uncommon in fast-moving technology (will Apple give you credit for your 2 year old iPod, or Dell for your old lappy?), but we want to do it anyway. We really do appreciate all of your business, and we want you to continue to grow with us. What's better than being sure that your past financial investment will continue to be an investment in the latest products from Dynon?

What are the advantages of connecting my SL30 to my EFIS-D10A (or EFIS-D100 or FlightDEK-D180) via an HS34 vs connecting it directly?

Connecting an SL30 directly to an EFIS, the SL30 can only send data TO the EFIS.

Connecting an SL30 to an EFIS via an HS34 enables:

  • EFIS transmits course data to the SL30
  • If a Garmin X96 is also connected to the HS34, EFIS transmits frequency data (from the X96) to the SL30
  • Easier switching between navigation sources via the buttons on the HS34
