Richard, I'm curious -- can you get into more details about these UI improvements.. and also if you can mention what's wrong wtih other units, so we better understand what exactly is being referred to in your previous post.
PS.. As for my own comment.. I keep seeing same thing over and over again.. EFIS and engine monitor.. be honest, I'd prefer they bring something new to the market.. a competition to GRT's Lite offering with their Sport + moving map + engine monitor. They need some competition there (at relatively similar prices).
I think the other posters have summed it up pretty well. It is quite a personal thing but I think you have to work out what it is that you want. For me my priorities are:
* Stable AH without gyros and at a comparable cost
* Replace as many flight instruments as possible i.e G meter, clock etc
* Enough screen space to display everything I need or share with my co-pilot if the workload is low
* Integrated EMS with voice prompting so I keep my eyes outside
* Not having to flip screens away from my AH under NVFR or IFR
* Simple to operate while still keeping eyes outside
* Believe it or not, I also want a real DG/HSI - tapes are nice, full DG cuts down a lot on mental work IFR and aids my situational awarenes.
* Autopilot separate from the EFIS for redundancy. I see people installing two units and an AP
* Minimum ongoing cost
I think it is fair to say that many of the expensive EFIS systems are going into VFR aircraft and are almost being used as toys. Sure they are good and offer some nice features. But can the owner every really get the value out of them and would he/she be better getting IFR instrumentation for the same price? That is a very personal thing.
You notice there is no moving map in the list above. For a VFR aircraft without a GPS or other instrumentation I think an integral map would be nice and I understand the reasoning behind wanting one. However the quality of all of them is nowhere near what can be achieved elsewhere for less.
Take this piece of software ->
http://www.oziexplorer.com/ . For virtually nothing I can use the CE version to display real aviation charts on my IPAQ or tablet PC. These are available in Australia as a digital file precalibrated to be used in this sort of tool. Nothing (perhaps with the exception of a Garmin MX20) can compete with that. I can swap between charts, zoom in and out all with a simple touch screen.
In Australia satellite based radar is not available, otherwise I would be seriously looking at the Garmin 395.
Both of these options make a certified GNS480 look reasonably primitive although to be fair it was not designed as a moving map display.
