Dynon or UAvionix with legacy generator

[Scott MacKie]

Got the stock generator in my Pacer. Have a venturi system driving a DG and an AI. Thinking of pulling. So: any issues with the load of the Dynon (D-3) or Uavionix (-30) when the generator is not on the step (in my case, above 1100 RPM with strobes, nav lights/ADSB, and radio going.

IMO better information, lose weight, and lose the g-awful looking monster Venturi's on the side of the airplane. Don't fly it in the clouds, don't intend to.

Thanks
Scott

Each AV-30 will require a 2 amp fuse. Not sure what the Dynon draws.

Why not spend the money on an alternator conversion and just pull the vacuum system out completely?

I can’t comment on the Dynon, but the AV-30 will actually consume approximately 0.5 amps while running. I wouldn’t expect there to be a problem with their operation at low engine speeds and no generator output but I haven’t seen one operating in those conditions either.

I run a generator with a full ifr panel. 430, 225, two G5’s, all led lights, transponder, audio panel, turn coordinator, double usb charger.
I did a load test, every single thing in the airplane on, including pitot heat and I still met the requirements with a 35 amp generator.

Your generator was installed years ago when all our radios were tube type and current draw was a lot higher back then.

With modern avionics, LED position lights and LED landing lights, the electrical load has been greatly reduced. Old style panel lighting can also draw a significant amount of current, so you might investigate that as a power saving modification.


Good luck

Generators get a bad rap, but they work!
I will not give mine up, sure, its heavy and a lightweight alternator would save some pounds. BUT, with my generator, I can have a battery failure, or forget to turn the master off and after a quick hand propping, I am back in business. But, just in case the generator AND the battery crap out, I have full mechanical instrumentation backup. I guess I am old school.
Get mine over 900 rpm and its charging. The old saying of "If it isnt broken, don't fix it", comes to mind.
