Key Takeaways Air density affects aircraft performance, including lift, engine power, and propeller effectiveness. These include lift, propeller thrust, and engine combustion. This increased density increases airflow over the wings, generating more lift. Fewer air molecules result in less dense air, which means less lift.

More air molecules in engine cylinders allow the engine to produce more power; more air molecules moving across the propellor blades and wings means more efficient thrust and lift. As altitude increases, air molecules spread out, resulting in less power and lift. When we reached the OATES intersection, I pointed the Six toward Winslow.
