As pilots, we love altitude. So much that we’ve created a bunch of different kinds of altitude: true altitude, absolute altitude, indicated altitude, assigned altitude, and two kinds of confusing ones – pressure altitude and density altitude. For many pilots, this can lead to a mental overload. Many pilots don’t have a working understanding of pressure and density altitude. Are they even real altitudes at all?
In this seminar, SCFC CFI’s introduce and explain the terms “pressure altitude” and “density altitude” and demystifies their meaning. Although the word “altitude” is used, these are clearly not measures of altitude. In fact, they are measures of atmospheric pressure and density just converted into units that pilots can understand. Confusing at first, yes, but once understood they serve a valuable purpose in determining aircraft performance.
Although few things are as important to a pilot as knowing the performance capability of the aircraft before taking to the skies, measuring the critical factor – atmospheric density – is not something that pilots can do directly. Instead we use rules of thumb, conversion factors, and our best understanding of how elevation, pressure, temperature, and humidity are interrelated. If you’ve ever opened your aircraft POH to the performance section and felt humbled, this seminar is for you.
