Recognizing the influence of ground effect during an approach to land is primarily done by observing the phenomenon known as "floating." Ground effect occurs when an aircraft is close to the ground, typically within one wingspan's distance. It causes an increase in lift and a reduction in drag because of the distributed airflow around the wings, leading the aircraft to feel as though it is floating above the runway during the final moments of landing.

This floating effect can cause the aircraft to remain airborne longer than anticipated and may require adjustments in approach techniques. Pilots should anticipate this increased lift and manage their descent rate appropriately to ensure a safe touchdown. Observing the floating is a direct visual and physical recognition of the ground effect's influence, making it a key aspect for pilots to understand during landing operations.
