I have the GRT Sport 8.4 screen on the left side and a dynon d10a on the right. The EFIS panels coming on the experimental market are the greatest heads down display since leather seats. As Larry Geiger says, ?Let?s be careful out there.? The GRT is very competitive price wise, upgradable, easy to read and intuitive to use. Lots of things I like ? especially HITS and the flight director. It?s just math and software but dynon doesn?t like it. My neighbor is building a seven and is down to the wiring. He has been sitting, for a very long time, on a cut panel waiting for the promised radio from dynon. He?s losing interest and his skyview is on the bench losing warrantee. He?s not real happy.

At the dynon booth, I asked one rep to help me understand why I can?t get my d10a to calibrate to within 6 degrees hdg (which can create 30 ? 40 knot winds aloft error). He told me to ask Ian. I also asked him about the availability of the comm radio. Again, ask Ian. On the calibration, Ian, said, ?just do the best you can in lining up the aircraft on the compass rose and keep the magnatometer away from metal.? Okay, that?s as good an answer as any. On the radio, he said, ?It?s still coming.? Check dynon?s post #2 on this thread; the radio, clearly is not their next high priority (maybe after weather and data logging?). As all EFIS systems evolve, more features will be added which will take each manufacturer time. Stein says GRT is slow. I disagree. Also, reread Vern Little?s post #23. That?s a pretty unbiased opinion.

Take a look at GRT HXr. Compare the cost to update the data bases. Compare the cost to upgrade. But, if you want a name, B$U$Y$ the garmin.

The radio absolutely is an active engineering project for us, but nobody should be waiting for our radio. At no point have we ever given anyone a date on the radio, and we do that on purpose so nobody bases a decision on the existence of our radio. We apologize if anyone got the impression that there was a specific date on which we would be able to deliver one, and we would happily refund any purchase that was made on that information.

Default Got It Backwards

To turn the thread concept upside down, the EFIS' already have too much integration, codependency, and button pushing, plus slot-machine whirling graphics (SV & HITS) that often obscure the really important information. They're quite capable of turning confusion into disaster.

First issue: you should not be able to loose the horizon in any manner, ever. The G3X is the only one I know that this is the case. All the others invite losing the AH and/or DG/HSI by pushing the wrong button.

Second issue: they want a lot of button pushing. Comm, transponders, SV, HITS, autopilot, intercom, nav, GPS... it's real easy to screw up.

Third issue: all your eggs are in one basket with all the integration.

Ol' Blue (#2 RV-7) is so easy to fly because the various functions are independently distributed in separate boxes. The TT AP is that thingy over there. Fiddle with that for AP. A D6 is the AH, atop a D10A for the HSI. Never touch those. That thingy over there is the GPS supplying guidance to the Dynons. Fiddle with that for navigating. Those thingies further over are the nav/comm atop a transponder. Fiddle with those for nav or comm or xpndr-ing. NO access buttons, no sub-menus to get to what you really want to fiddle with. It's blindingly obvious and your right-seater can help.

I shopped, boy did I shop. I can buy newer (which is to say still supported by Garmin) but the obvious trend is all-in-one. That might save a few bucks or a coupla' square inches of panel space. But you loose easy comprehension and failure constraint.

So look at all those twinkling EFIS' with a jaundiced eye. What features are you really going to use and how many buttons must you push to get to them?

Please look outside once in a while.

Issue 1. I have a GRT Horizon and it can be set up with the PFD locked, e.g., not possible to select a page without the horizon on it.

Issue 2. I guess I'm with you here; while the efis can select com frequencies on the SL 30 I prefer to enter them directly. I think It keeps me more in the loop.

Issue 3. I use a D6 as a completely independent backup, including a self contained battery. And battery operated gps and vor for navigation. I cannot believe anyone operates IFR with all their eggs in one basket.

Wow...been reading this thread and I'm amazed at the responses garnered around minor enhancements. I don't think anyone should make purchasing decisions over what something DOESN'T have. Look at the SV system vs price and it's a remarkable value with a multitude of major bells and whistles.
Have a neighbor who flies a Questair and is obsessed with weather. Wanted to spend 6k on a small receiver with a rats nest of wires just to get ADSB traffic. For not that much more you get a fully integrated system that has SV, EMS, full mapping with no update charges, ADSB compliant transponder, weather, traffic, ADAHARS, EFIS, autopilot, etc also with FREE future software upgrades and numerous optional enhancements constantly coming down the pipe.
Don't cry over what you don't have---count your blessings.
