What is one of the main functions of flaps during approach and landing?

Flaps are crucial for enhancing the aerodynamic performance of an aircraft during approach and landing phases. One of their main functions is to increase the lift generated by the wings at lower speeds, allowing the aircraft to maintain a safe flying attitude while descending. By extending the flaps, the aircraft can achieve a steeper angle of descent without the need to increase airspeed significantly. This capability enables pilots to manage their descent path more effectively, ensuring a controlled and safe landing approach without accelerating towards the runway.

The use of flaps not only helps in controlling descent but also stabilizes the aircraft during these critical phases, allowing for smoother transitions and adjustments as needed. This is particularly important as the aircraft approaches the runway, enabling the pilot to maintain the desired glide path while adhering to specified safety protocols.
