In addition I installed an SD-8 engine driven alternator with a separate alternator switch and SD-8 alternator switch as a backup as well.

That way if there's a total electrical failure, failure of either EFIS computer or display there's still something working with all attitude, heading, airspeed and altitude info.

I just wanted to say that my Grand Rapid units have performed perfect for 80+ hours. There have been no performance issues. I do have issues with menus and some functions but nothing on it's reliability. Depending on the kind of flying you do, GRT might be a good system for you. Customer service is the best and my units arrived couple of weeks early. Do not archive.

For those who are planning an EFIS, even a reliable and expensive one, don't forget to put backup gauges in for the critical stuff. I've seen a few EFIS-only panels already, and I can't help but think there's something to be said for non-electric, or at least self contained backups. Check out this story on a G1000. http://www.alexisparkinn.com/nwpilot's_tranatlantic_flight.htm And I got a copy of this service alert from Avidyne. http://www.myrv10.com/files/avidyne/SA-05-001.pdf You'll see that even they now specify backup instruments after having issues with their systems. So I haven't heard of an EFIS yet that doesn't have at least some issue. Dynon's were previously famous for losing attitude when the system loses airspeed. BMA has had all sorts of things. Chelton has had the Crossbow 425 stuff. OP tech has had some interesting issues. So plan your panels accordingly....and remember these things are programmed by humans....hopefully not the same ones who wrote Windows 95. :) -- Tim Olson - RV-10 N104CD - Flying do not archive - The RV10-List Email Forum - Thank you for your generous support! Subject: RV10-List: Fw: Emailing: PA050075.JPG backup instrumentation Just installed a GRT Sport in the Glastar. picture included. The 10 is a dual battery, dual buss, single alternator. Instrumentation is dual Cheltons (gadahrs), Digiflite autopilot (internal gyros) and TT 2,25" ADI (if they build it). Three ways to fly the aircraft in IMC. ----- Original Message ----- From: David McNeill Sent: Friday, October 06, 2006 8:53 AM Subject: Emailing: PA050075.JPG The message is ready to be sent with the following file or link attachments: PA050075.JPG ________________________________ Message 4 _____________________________________ Time: 09:22:16 AM PST US From: Jeff Carpenter Subject: RV10-List: Not the best publicity... --> RV10-List message posted by: Jeff Carpenter http://www.tulsaworld.com/NewsStory.asp?ID=061006_Ne_A1_Inhof10315 Do Not Archive ________________________________ Message 5 _____________________________________ Time: 10:40:29 AM PST US Subject: RV10-List: Re: Not the best publicity...

The MFD thumbnail sits to the left of the EHSI and while probably not as convenient as having an overlay "white" line it does give you information in front of you. The G 1000 system I fly has a King Auto pilot which I'm sure is not as convenient as an integrated auto pilot such as the STec 55 system...FYI.

Also, I think this is a better location because in a forward inpact crash, the body will be thrown forward and the belts will be the in the truest opposite direction coming from the longerons. Thanks for the comments on the web site. I am no where near working on the cabin top so unless someone knows it chemical makeup, I will ask Van's later.
