* Density altitude is the altitude corrected for non-ISA International Standard Atmosphere atmospheric conditions.

* Density altitude – the density of the air in terms of altitude in the International Standard Atmosphere

Density and pressure decrease smoothly with altitude, but temperature ( red ) does not.

Density altitude is the altitude in the International Standard Atmosphere at which the air density would be equal to the actual air density at the place of observation, or, in other words, the height when measured in terms of the density of the air rather than the distance from the ground.

" Density Altitude " is the pressure altitude adjusted for non-standard temperature.

Density altitude can be calculated from atmospheric pressure and temperature ( assuming dry air ).
