I was wondering if I could get some advice explaining density altitude to one of my students.
He understands that the higher we fly and the hotter the temperature the less dense the air is. But, what he doesn't understand is why. I told him that there is less air molecules for the prop to work with so we will get less work out of the engine etc. I also talked about it taking a bigger bite out of the air since there is more air molecules.
He seems to think that since there is less air molecules we will get less drag so then we should get better performance. I told him we are getting less drag because we are getting less lift.
Maybe if I show him how the prop is an airfoil?? That's the only thing I can come up with so far. Any help simplifying this would be much appreciated.
