Density Altitude Formula: How to Calculate it Correctly

Northstar VFR

Indicated altitude is the altitude read directly off the altimeter. If you set the altimeter to the standard 29.92, you can read the pressure altitude off of the altimeter. Let’s take KBJC’s field elevation of 5,673 and say the altimeter setting was 30.10. Pressure altitude is corrected for non-standard temperature.
