WebMay 21, 2024 · The ground effect can affect airplanes in several ways. As previously mentioned, it’s responsible for increasing an airplane’s lift and decreasing its drag during landings. Airplanes with fixed horizontal wings create air disturbances at their wingtips and behind their wings known as vortices. An airplane (also known as an aeroplane or simply a plane) is a powered fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Planes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for planes includes recreation, transportation of goods and people, military, and research.

For fixed-wing aircraft, ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a fixed surface. Reduced drag when in ground effect during takeoff can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached.
