Calculating density altitude is like filing your taxes; annoying and often neglected until the last minute, but crucially important. Why is density altitude critical to ensuring safety, what factors affect it, and how is it calculated? Today is the day that the mystery of density altitude is solved.

This ensures everyone is reading the same altitudes. Density Altitude Density altitude is my personal favorite, and the reasoning is simple. It’s the altitude at which your airplane thinks it's at. When checking your ATIS (or AWOS/ASOS), sometimes you’ll hear at the very end “Density Altitude feet”.

2: What effect does high density altitude have on the efficiency of a UA propeller? Density altitude does not affect propeller efficiency. 1: To avoid a possible collision with a manned airplane, you estimate that your small UA climbed to an altitude greater than 600 feet agl. Example question No.

While calculating an aircraft’s performance, you must take into account ground effect, particularly when operating on short runways or in high-density altitude areas. For example, a Cessna 172 with a 36-foot wingspan will begin to experience ground effect between 30 and 36 feet Above Ground Level (AGL).

At approximately 30-40 feet agl, the spinning stopped and the helicopter appeared to stabilize for a brief moment before continuing a nose-low, forward descent into the grass north of Runway 28. When it stopped climbing, the helicopter maneuvered erratically drifting towards the north and descending. As it descended it spun around 2-3 times.

Temperature An increase in temperature will increase the density altitude. A high density altitude decreases the performance of the engine and the wing. Your aircraft will fly at a faster true airspeed at higher density altitudes. x V SO (or POH recommendation) by around 500 feet AGL.

Northbound general aviation corridor altitudes are 11,500′ or 13,500′; southbound altitudes are 10,500′ or 12,500′ [as of June, 2021 – check a current chart for changes]. Altitude Caution Flying a normally aspirated (non-turbocharged) aircraft? Be sure you know your aircraft’s capabilities.
