Aircraft fly because of lift generated by the wings. The engines merely provide the forward thrust to drive the wing forwards. As air passes over the wing, the difference in pressure between the top and bottom surfaces, and the angle at which the air hits the wing, creates lift. However, not all air is the same. dauphine libere cycling

WebAir pressure changes with altitude. Air is all around us, but we cannot see it. Gravity from the Earth pulls air down - this is called air pressure. We don't feel this pressure because our bodies push an equal amount of pressure outward. This graph shows how air density and air pressure changes with altitude (the distance above sea level). WebHow Does Altitude Affect Blood Pressure? When you are at sea level, your blood pressure is usually around 120/80 mmHg. At high altitudes, your blood pressure can rise to as …

The human body can perform best at sea level, where the atmospheric pressure is 101,325 Pa or 1013.25 millibars (or 1 atm, by definition). The concentration of oxygen (O2) in sea-level air is 20.9%, so the partial pressure of O2 (pO2) is 21.136 kilopascals (158.53 mmHg).
