How To Figure Out Density Altitude. Density altitude is commonly referred to as the actual altitude at which the plane “feels” it’s flying. Density altitude = 7420 + 3047 density altitude = 10467 feet the increase from the temperature correction results from the fact that the temperature is above the isa temperature for that altitude.

If that seems all too much for you to remember, then try this quick formula: The definition of density altitude is the altitude at which the density of the 1976 international standard atmosphere is the same as the density of the air being evaluated. Oat is ‘outside air temp’ or the thermometer reading in celsius and isa temp is the international standard atmosphere temp.
