Question

Quizplus · Accepted Answer

Wing slots, also known as leading-edge slots, are a type of high-lift device used to delay or prevent the stall of an aircraft wing. When airflow over the wing separates (stalls), lift is greatly reduced, and the aircraft may lose altitude or even enter a spin. Slots improve the airflow over the wing, enabling it to generate more lift at lower speeds and higher angles of attack before stalling occurs.

Therefore, the best choice is B, in preventing or delaying stalling.
