WebMay 13, 2024 · As the altitude increases, density, pressure, temperature, and the generated lift decrease. With a decrease in density, the drag on the plane decreases. In other words, in "thin air" there is no drag, essentially. However, this in turn affects the lift that is needed to keep the plane in the air. To compensate, the engines should produce more ... WebFeb 19, 2024 · With lower air density, a naturally aspirated engine cannot make more power when there is no supercharger to compensate. Aerodynamic drag reductions may not overcome the power loss. Highly streamlined race car bodies can see minimal improvements in aerodynamic drag reduction from high altitude.
