- An atmospheric density expressed in terms of the altitude, which corresponds with that density in the standard atmosphere. It is the pressure altitude corrected for temperature. Density altitude is used for computing and predicting aircraft and engine performance, including takeoff, climb, and landing performance, instead of true or pressure altitude. On most computers, it can be read directly when calculations for true air speed (TAS) are made.Calculation of density altitude when pressure altitude and temperature are known.
