What is induced drag?

Induced drag is a type of aerodynamic drag that arises specifically as a byproduct of the generation of lift. When an aircraft's wings create lift by generating a pressure differential between the upper and lower surfaces of the wings, the air pressure creates vortices at the wingtips. These vortices effectively increase the drag experienced by the aircraft, which is known as induced drag. This phenomenon occurs because the airflow over the wings is disturbed, and the resultant vortices lead to a reduction in overall lift efficiency. Understanding this drag is crucial for pilots and engineers, as it significantly impacts fuel efficiency, climb performance, and overall aircraft operation, particularly at lower speeds and angles of attack, where lift requirements are greater.

Other options touch on different concepts related to drag or forces but do not accurately define induced drag. Therefore, focusing on induced drag's relationship with lift generation clarifies its significance in aviation dynamics.
