COLD TEMPS
The GSU 73 is rated to -85 Dec C. For this reason alone I was set on a G3 being my next EFIS.
The last 3 EFIS failures I have had all happened in -10 to -18 C with units rated to -20. These were not Garmin systems.
To quote Matt, " First, the GSU 73 will absolutely still be supported for those who have one, or decide they want to buy one. However, as you pointed out, the new black boxes are lighter and less expensive - thus is the nature of technological progress. "
What are the temp spec limits for the new GSU 25? Will it work with no AOA probe or data?

GMC 305
Matt,
Is the GMC 305 Autopilot controller the unit that you had in mind to replace the AICD in the Doll's panel?

AOA input is optional and you can leave it off you want.
The draft version of the installation manual I'm looking at right now lists an operating temperature range of -45C to +70C for both the GSU 25 and GSU 73. You should see the clouds that form when the liquid nitrogen truck pulls up to top off the big storage tank that we use for production testing!  I believe the -85C figure you are thinking of is actually the lower limit for total air temperature (i.e. OAT) which is +/- 85C.

Hi Danny,
The GMC 305 is about the same height as your CD player, so I imagine it would work just great in your panel. As an ex-airline guy I'm sure you will have a special appreciation for the benefits of a dedicated AFCS mode control panel.

G3X
I was just drawing out options for my RV-8 panel last night. This will be a game changer.
I have a VM-1000 now. Will the probes, etc work with your engine module?
Thanks,
John

I do, and I think it will be a real asset. Gee, I thought I was done with the Doll's panel after installing the GTX 330es and GDL 39. These airplanes are never really finished!
Thanks for all your help.

Hello John,
Typically what we tell people who are converting from another engine monitoring system is that they will be able to re-use about half their sensors, especially their thermocouples. As for the rest, since we don't know exactly which sensors you have, the easiest way to determine if what you have will work is to take a look at Table 8-1 and appendixes E & F of the current G3X installation manual. The same probes will be supported for both the GEA 24 and GSU 73.

Matt,
Any talk of adding the AOA variable to the serial text output? I would love to have my remote AOA display back in action!
