What is one result of an aircraft being in ground effect during landing?

Being in ground effect during landing leads to a phenomenon where the wings of an aircraft experience an increase in lift due to reduced drag when close to the ground. This effect occurs typically when the aircraft is within a wingspan's distance from the surface. The presence of the ground inhibits the formation of vortices at the wingtips, which normally increase induced drag at lower altitudes.

As a result, the aircraft can maintain lift at a lower airspeed than it typically would require, allowing for a shorter landing distance. This is particularly beneficial during the landing phase, as it enables the pilot to touch down at a more manageable speed and achieve a safe, controlled landing while utilizing less runway. This efficiency is crucial, especially on shorter runways or in landing situations requiring precision to avoid obstacles.

Understanding ground effect and its impact on landing distance is an essential aspect of flight training, helping pilots make informed decisions during landings.
