ground effect
- noun
- /ɡraʊnd ɪˈfɛkt/
- Specialized
- So, as the plane is relatively stationary to the surrounding air (there's some air moving due to the ground effect of a moving conveyor), it cannot lift.
- ground effect craft
- ground effect flight
- ground effect machine
Does anyone know what ground effect is only a only a couple of you.

Examples
-
The conveyor moving in the opposite direction would drag a bit of air backwards with it, increasing the relative airspeed of the wing and increasing its lift (there may be some additional ground effect in play here that assists the takeoff as well...).

Except for very low altitudes, which is the ground effect and results in much reinforced lift.

Flying close to the runway, the airplane utilized ground effect to achieve a smoother landing.
-
The design of the aircraft maximizes ground effect, allowing it to fly efficiently at low altitudes.
-
Pilots often rely on ground effect to reduce fuel consumption during takeoff and landing.

Morphology
The phrase is transparently built from 'ground' + 'effect' so a B1 learner would correctly infer it denotes some effect produced by or related to the ground. However, the specific technical sense (increased lift and reduced drag for aircraft flying very close to the surface) is specialized and not fully predictable from the constituents, so learners would only get a vague idea without prior exposure.
Etymology
Ground effect comes from the image of a plane flying very close to the ground, where the effect of air squeezed under the wings acts like a soft cushion. This pushes the plane up and reduces air resistance, so the phrase means 'more lift and less drag' when an aircraft is near the ground.
