An aircraft flying in "ground effect" will produce
- more lift than a similar aircraft outside of ground effect.
- less lift than a similar aircraft outside of ground effect.
- the same lift as a similar aircraft outside of ground effect.
Explanation
Close to the ground the wingtip vortices and downwash are physically restricted by the surface. This reduces the induced downwash, effectively increasing the angle of attack and reducing induced drag, so the wing produces more lift for the same conditions. Ground effect therefore gives more lift than the same aircraft flying clear of the ground.

Ground effect - the effect of added aerodynamic buoyancy produced by a cushion of air below a vehicle moving close to the ground.

Ground effect - the effect of added aerodynamic buoyancy produced by a cushion of air below a vehicle moving close to the ground + it acts exactly when the altitude is equal to the wing span. (its due to induced drag)
