AOPA Aerodynamics Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is the definition of lift? Lift is the upward force generated by the wings of an aircraft as air flows over them, allowing the plane to rise. What is drag in aerodynamics? Drag is the resistance an aircraft experiences as it moves through the air, opposing forward motion. What is thrust? Thrust is the forward force produced by an aircraft's engine that propels the airplane through the ...

When the angle-of-attack of a symmetrical airfoil is increased, the center of pressure will A —move aft (rearward). B —move forward. C —not move. C —not move. A symmetrical airfoil moving through the air at zero degrees angle-of-attack A —will generate a low static pressure above the wing and a high static pressure beneath the wing. B —will produce a high pressure above the wing and a low pressure beneath the wing. C —will cause similar acceleration of the airflo...

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...
