Document Summary
Critical angle of attack: causes stall if exceeded. Laminar flow: thin layer of air hat is smooth and adheres to the wing. Transition point: when airflow changes from laminar to turbulent: the greater the aoa the further up the transition point on the wing. Atmospheric conditions (pressure) and airflow relative to the airfoil: to recover from stall push nose down and add full power, the heavier the aircraft, the higher the stall speed. Heavier aircraft have a higher angle of attack to climb compared to lighter planes. (same speed for both, but different angles) Centre of pressure: centre of lift forces, as the angle of attack changes so does the centre of pressure. Moves forward till critical angle, when that is reached the cop will move backwards (helps during stall, pushes nose down if the centre is further backward) Climbing turns (do not exceed gentle bank: higher aoa causes plane to overbank.
