GROUND EFFECT Meaning and
Definition
-
Ground effect refers to the aerodynamic phenomenon that occurs when an aircraft is flying in close proximity to the ground or any other surface. It describes the increase in lift and decrease in drag that a flying object experiences when it is within one wingspan length or less from the ground. In this state, the aircraft is said to be operating in the ground effect.
When an aircraft flies in the ground effect, the air pressure below the wings is compressed due to the close proximity of the ground. As a result, this compression increases the lift generated by the wings while reducing the induced drag. This allows the aircraft to experience greater lift and efficiency at lower speeds.
Ground effect is particularly noticeable in low-winged aircraft that have wings positioned close to the ground. The increased lift and reduced drag experienced in ground effect can enable these aircraft to take off and land at lower speeds, resulting in shorter distances required for both procedures.
The ground effect is also utilized by some watercraft, such as hovercrafts, which use a cushion of air to maintain lift and reduce friction. Additionally, ground-effect vehicles (GEVs) apply this principle to achieve high speeds by coasting just above the water surface, minimizing drag and increasing efficiency.
Understanding ground effect is crucial for pilots, as it affects the control and performance of an aircraft during takeoff, landing, and low-level flight near the ground. It requires careful consideration and adjustments to the aircraft's flight controls to ensure safe and efficient operations in this specific aerodynamic state.

Etymology of GROUND EFFECT
The term "ground effect" is derived from aviation and refers to a phenomenon where the lift and drag experienced by an aircraft change when it is in close proximity to the ground.
The word "ground" originates from the Middle English "grounde", which is derived from the Old English "grund", meaning "the surface of the earth". It can be traced back to the Proto-Germanic word "grunduz" and the Proto-Indo-European root "ghrendh-".
The word "effect" comes from the Latin "effectus", which means "accomplishment" or "performance". It is derived from the verb "efficere", which combines "ex-" (meaning "out") and "facere" (meaning "to do" or "to make").
