"Witryna8 sie 2024 · Lift and Weight. As air flows around an aerofoil the pressure differential setup over the upper and lower surfaces produces a force. This force acts perpendicular to relative airflow and is known as lift. In steady level flight, lift exactly balances the aircraft’s weight. For a given airspeed, a lower weight requires less lift.
