How do spoilers help during landing?

1. By increasing lift

2. By reducing speed and assisting brakes

3. By altering the shape of the wing

4. By providing lateral stability

The correct answer is: By reducing speed and assisting brakes

Spoilers play a crucial role during the landing phase of flight by reducing the lift generated by the wings, which consequently aids in lowering the aircraft's speed. By deploying the spoilers, a pilot can disrupt the airflow over the wing, which causes a decrease in lift. This decrease allows the aircraft to descend more rapidly and helps control the landing approach and touchdown process more effectively. Additionally, by reducing lift, spoilers allow the aircraft to settle onto the runway sooner, thereby enhancing braking effectiveness. When the spoilers are deployed, they also contribute to increased drag, further slowing the aircraft down upon landing. This combination of reduced lift and increased drag is advantageous for maintaining safe speeds during the critical landing phase. Other choices do not accurately reflect the primary function of spoilers. For example, spoilers do not increase lift or provide lateral stability; their main purpose is to manage lift and drag during landing to improve overall control and safety.
