Hi, Long time listner, fist time caller,
I am having an arguement at work. I believe that on a C172 the flap motor will draw less current than the beacon and all avionics on.
If the flap motor was the only thing running, it would flatten the battery slower than if the beacon and all avionics were on.
The avionics that are on are: GPS, 2 x VHF, and transponder.
My arguement is that if all those things are on plus the beacon, the battery would drain quicker than if it had to power the flap motor.
Look forward to the replies.
