What is a primary function of spoilers?

The primary function of spoilers is to reduce lift and increase drag during descent. Spoilers are devices found on the wings of many aircraft. When deployed, they disrupt the smooth airflow over the wing, decreasing lift, which aids in the descent by allowing for a controlled reduction in altitude. This function is particularly useful during landing as it enables the aircraft to descend more steeply without increasing airspeed. Additionally, by increasing drag, spoilers contribute to effective speed management, helping to slow the aircraft down during approach and landing phases.

Understanding this function highlights the significance of spoilers in aircraft operations, especially in the context of safe and efficient landings. While the other options may describe other characteristics or purposes of aircraft systems, they do not accurately reflect the primary role of spoilers in managing lift and drag during flight.
