We all deal with engines, so we should know about their relationship with air pressure and density. Query any serious bracket racer, and you'll find he's become a virtual closet meteorologist.

A barometer also monitors variations in atmospheric pressure. As air becomes thinner, the density of air decreases, and so too does the pressure of air. Many different factors affect the density ...

As you move higher in elevation, air density decreases. Air density isn’t the simplest thing to model. It depends on the pressure and the temperature (both of which change with weather).

If the aircraft is operating from a high-elevation field, for example, taking off from an airport in the mountains where there is reduced air pressure, we have the trifecta of density altitude ...

causing its density and consequently its air pressure to decrease. Changes in elevation cause air pressure to change because air pressure at any given level is the weight of the air above you.

However, sometimes the actual pressure is different because of weather conditions. This differential affects air density and how the aircraft performs. If the air density is higher, the aircraft ...
