We responded directly via email to your "keep alive" question. For this question, yes even if you power down the G3X Touch displays, ADAHRS, engine interface, etc and keep the the GAD 27 powered, it will still respond to the flap and trim switches and drive the trim and flap motors in a manual mode. Thanks, Steve |
Excellent. Thanks Steve. Much appreciated.

GAD 27 keep alive
G3Expert please post the answer to the GAD27 power question about the keep alive circuit. I am installing the system as well and have wondered about the same question.
Thanks! |

The most common way to power the PFD (GDU 4XX), ADAHRS (GSU25), and Engine Monitor (GEA24) in a system using the GAD27 conditioned power (keep alive) output is to wire the Power 1 pins on each to the aircraft main power bus and the Power 2 pins on each to the GAD27 conditioned power output. When this is done, main bus voltage drops which occur during engine cranking will not affect the PFD/ADAHRS/Engine Monitor which are up and running before starting the engine. This, of course, also maintains the GPS fix that the PFD may have already established before you started the engine. Let us know if you have additional questions. Thanks, Steve |
Steve, Thanks for the post!

Thanks Steve
Very informative Q & A session. Much appreciated.

I am retrofitting the G3X into my RV-7. Is there a way to use my current trim/flap position indicators as well as the G3X? Not sure how I would wire it with regard to the +5v from the GEA 24.
Anyone done this? Thanks! |
Vans Flap Positioning System
I am about to order the RV-10 Fuse Kit and would like to go with GAD27 to operate the flaps. Will I need the FLAP POSITIONING SYSTEM from Vans?
Thanks! |
Nope! The GAD27 will do it for you. What you do need is a flap position indicator to show you where the flaps are positioned on the G3X screen. I used a Ray Allen POS position indicator to do the job. Works great!

Kent, many thanks for your speedy reply!
