That's why light aviation aircraft still use carburettors with their
attendant intake icing and falling out of the sky problems when a simple
replacement with fuel injection would fix the problem. It's too expensive
to
certify the safer solution often.

I'm not sure, but don't light aircraft engines have to run without battery
power.
