What flaps position should be set when preparing for landing, according to the checklist?

The flaps position set when preparing for landing is typically "Full." This configuration is designed to increase the lift generated by the wings at lower speeds, which is essential during the landing phase. By deploying the flaps to their full position, the aircraft can maintain a stable descent rate and a controlled approach to the runway. Full flaps also help to reduce landing speed, allowing for a safer and more manageable landing process, particularly in various environmental conditions such as strong winds.

In many aircraft, the full flap setting maximizes the wing's surface area and alters the wing's curvature, which results in increased lift. As a result, pilots are better equipped to handle the aircraft at lower speeds during final approach and touchdown. Therefore, the checklist's guidance to set the flaps to "Full" is a critical step in ensuring a safe and effective landing.
