Oct 6, 2023 · Let’s walk through a quick example. Imagine you’re at an airport with an elevation of 1500 ft, and the current altimeter setting is 29.42 Hg: Pressure Altitude = (29.92 − Altimeter Setting) x 1000 + Elevation. Pressure Altitude = (29.92 – 29.42) x 1000 + 1500. Pressure Altitude = (0.50) x 1000 + 1500.
Pressure is a measure of how concentrated (or spread out) a force is. The amount of pressure exerted on an object depends on the force applied and the surface area it is spread over. We can ...
