Pressure altitude is used to determine your aircraft’s performance in non-standard conditions, which are any time the barometric pressure is anything other than 29.92 Hg at sea level.

Atmospheric pressure Whenever rain or bad weather moves into a region, it’s often associated with the appearance of a system of low atmospheric pressure. But what exactly is atmospheric pressure?

As barometric pressure falls, tissues around joints can expand or swell, leading to pain, especially for those with arthritis. If colder temperatures accompany the pressure drop, that can lead to ...

At sea level, the average pressure is 1.013 bars. We use the sea level pressure standard to determine if air pressure will be relatively high or low as weather systems move over us.
