I'm New Here
Okay, I'm not building a Vans - I'm building a Rans S-21, but this forum is full of good knowledge so I'm hoping you guys will share it!
I'm planning out the avionics / electrical system now. My plan is to have dual independent electrical buses (which is a whole other topic for debate that I don't want to get into in this thread!).
The question is: I notice the Garmin GMC A/P controllers all have dual power inputs, i.e. "AIRCRAFT POWER 1" and "AIRCRAFT POWER 2", diode connected like all Garmin dual-power avionics. Yet the GSA28 servos have just a single power input.
What is the thinking here? What good is it to allow the A/P controller to have redundant power inputs when the servos themselves have just a single power input?
Seems like you'd just want to connect the GMC to the same bus as the servos are connected to. Connecting it additionally to the other bus would just allow the GMC to light up, I guess, but without the servos having power, that seems pretty pointless.
I think I am missing something - can someone enlighten me?
Thanks!
