WebNov 24, 2024 · Atmospheric pressure (P atm) is the weight of the air as the Earth’s gravity pulls it toward its center. It is heaviest at sea level (more atmosphere above it), which is measured at 14.7psi (1.01325 bar). At higher altitudes, atmospheric pressure is different, so it’s important to know the pressure at your altitude. Webphysiological significance involved in flight are: marked changes in barometric pressure, considerable variation in temperature, and movement at high speed in three dimensions. Advances in aviation engineering in the past decade have resulted in the development of highly versatile aircraft. Since we are essentially creatures of the ground,
