I'm working to finalize an upgrade panel design that's been two years in the making, and I find myself going back & forth over what should be on the clearance delivery / brownout bus on Bob's new Z-101 architecture in a G3X, IFR panel.
If you were building a full-up dual-G3X plus GTN 650xi panel, what would you want on a clearance delivery bus? In other words, what all bits & bobs do you need to have online to call for a clearance & set up your flight plan prior to turning on the main bus for engine start?
And then, when you start the engine, what components are prone to restart due to low voltage? Instead of the TCW IBBS I see in a lot of these panels, I'm planning to use the TCW power stabilizer, which will provide up to 8A. I also have a GAD 27 in the mix, which can provide 3.5A of stabilized power if 8A isn't enough.
Finally, what do you absolutely want on pullable breakers vs. on fuses inaccessible during flight? Right now I have AP servos, pitch trim servo, and flap motor on breakers.
Thanks!
