How is lift primarily generated on a wing while in steady flight?

• A. Through the angle of incidence.
• B. By the airplane's weight.
• C. By the dynamic effect of the air on the wing.
• D. Through electrical systems on the wing.

Answer: (C)

Lift is primarily generated on a wing in steady flight through the dynamic effect of the air on the wing. When an aircraft is in motion, air flows over and under the wing, and this movement creates a pressure difference between the upper and lower surfaces. The shape of the wing, known as the airfoil, is designed to facilitate this pressure difference. As air travels faster over the curved upper surface, it reduces pressure compared to the slower-moving air beneath the flat or slightly curved lower surface. This pressure difference is what generates lift, allowing the aircraft to overcome its weight and maintain flight. The angle of incidence does influence the amount of lift produced by changing the airflow characteristics, but it is not the primary way lift is generated during steady flight. The airplane's weight itself does not generate lift; rather, it is the force that lift must counteract for the aircraft to ascend or maintain level flight. Electrical systems play a role in controlling various aspects of the aircraft, but they do not directly contribute to the generation of lift. Therefore, the dynamic interaction between the wing and the airflow is the key factor in lift production during steady flight.
