WebOct 1, 2024 · Density altitude is pressure altitude corrected for non-standard temperature. When it's hot outside, your airplane doesn't perform as well. Your takeoff distance is longer, and you don't climb as fast. That's because when it's hot, density altitude increases, and your airplane "feels" like it's flying at a higher altitude.
