Density altitude

The density altitude; calculates the density; of the air and indicates at which altitude this value should be present under normal conditions.

Altitudine di densità n.1

As the altitude increases, the air density decreases according to well-defined average references, but if the temperature or humidity increases, the air density decreases and therefore the density altitude is higher than the actual altitude of the measuring point.

This value is of fundamental importance in the aeronautical field, in fact it greatly influences the phases of take-off and landing.
