In
fixed-wing aircraft,
ground effect is the increased
lift (force) and decreased
aerodynamic drag that an aircraft's
wings generate when they are close to a fixed surface. When landing, ground effect can give the pilot the feeling that the aircraft is "floating". When taking off, ground effect may temporarily reduce the
stall speed. The pilot can then fly level just above the runway while the aircraft accelerates in ground effect until a safe
climb speed is reached.
