Definition#
Density altitude is the pressure altitude corrected for non-standard temperature. It represents the effective altitude at which the aircraft "feels" it is flying based on actual air density.
Why It Matters Operationally#
High density altitude (caused by high temperature, high elevation, or high humidity) degrades engine output, reduces lift, and lengthens takeoff rolls. It is critical for planning at hot, high-altitude airports.
