What flap setting is typically used for a normal landing?

For a normal landing, a flap setting of 20 degrees is typically used because it provides an optimal balance of lift and drag. This flap deployment enhances the aircraft's ability to descend at a steeper angle without increasing airspeed excessively. By extending the flaps to this angle, the pilot increases lift during approach and landing, which allows for better control and stability. Additionally, the increased drag helps to slow the aircraft down, enabling the pilot to manage the descent rate effectively and achieve a smooth landing.

Utilizing 20 degrees of flaps also helps in reducing the stall speed, which is particularly important during the final phases of flight when operating at lower speeds. The increased lift associated with this flap configuration improves the aircraft's performance in the landing approach, especially in various weight conditions and environmental circumstances.

While other flap settings like 0 degrees, 10 degrees, and 40 degrees may have their places in specific aircraft configurations or in different landing scenarios, 20 degrees strikes the ideal compromise for most light general aviation aircraft during normal landings, promoting safety and efficiency.
