We have 3 screens, GTN750, stormscope, old skool strobes and lights??etc??.60A is fine.
If I could have a 70-80A I would though. Better looking at it than looking for it! |
Low amps
I went with low amp led lights and just A 35 amp accessory pad mounted alternator. Less weight and efficient. Autoelectric is great source of info.

3 screen g3x with 650, all lights are LED, VPX, and a iphone and ipad charging on USB, and see 18 amps with all lights on. Only thing not on would be flaps/AP servos and Pitot heat. Have a 60 amp primary and 30 amp on vacuum pad. Would be fine really with the 30 amp only.

I went through this exercise and it was a really eye opener looking up all the conditions and details for power draw. In the end, it will be a documentation in phase i for the various flight configurations and amp draw.
Like a strobe, use surge or continuous, will it blow a fuse during surge? I did not know, but Stein said I would be fine so I moved on. 60A PP. Regardless of reaching a definitive answer, building the amp list and being adding checks for configurations to yield a total is a good thing to think through. It will be interesting to see how close the real numbers will be. One plus is LED landing lights, rather than the original planned incandescent. |
