I've forgotten how to use my whizz-wheel to calculate Density Altitude, so could someone answer my this, please?
A few weeks ago, a deep High Pressure system moved across South Ausralia and Victoria. I saw a pressure reading of something like 1040 hecto-thingies. If that was the airpressure, and the OAT was, say 15C, ignoring Moorabbin's height of 50 ft AMSL, what would the density height be with those meteorological conditions?
