Today would be a good day to fly for a while.
Clear skies, small winds, GREAT density altitude. (-5000 ft) and no chance of icing…..
Of course, there is the issue of getting the plane out of the hangar without frostbite, and I’m not sure I could get any oil temperature if it would start….and at -20F …i’m not sure the avgas won’t be frozen…
I’m going on Saturday though.
