Aerodynamic - Study guides, Class notes & Summaries

Commercial Pilot Operations- Aerodynamics & Principles of Flight 100% Correct 4 forces of flight Lift, Weight, Thrust & Drag. Accelerated flight Thrust exceeds Drag. Decelerated flight Drag exceeds Thrust. Lift Provides the upward which sustains the aircraft in flight. It is perpendicular to the relative wind. Lift Equation Coefficient of Lift * Wing Area * Air Density/2 * Velocity Four ways to control lift - Change the shape of the airfoil. - Increase airspeed. - Change the angle of attack...
