Were talking a low likelihood occurrence. You see rc guys flying in dry conditions. Its something where you plan to manage loss of life but doesn't restrict you generally. You take the steps to mitigate the risk, and ensure you understand them... Not refuse to fly. Otherwise you'd be refusing to fly anyway as you're much more likely to have a carb icing incident than a battery fire by statistics.That plan certainly wouldn't work for anyone flying electric aircraft in Ozzie at the moment. Actually one could probably have to add a fire ban check to ones pre-flight planning and just be prepared not to fly in summer.
