[NSRCA-discussion] Power consumption

Yes, the air density is important factor.  It affects even more IC engines.  I think power = constant x air density x RPM^2.  Therefore is linear with air density.  The constant is a number that is determined for each prop so assuming using same prop.

Subject: [NSRCA-discussion] Power consumption

I've been flying an E-power sport airplane and noticed that similar 10 min.
flights in cool air (40 deg) consumes about 90% as many MAH it took last
fall flying in 85-90 deg air. Does it really take more power flying in hot
thin summer air, or am I dreaming.
