When air flows over the aircraft wing, the shape of the airfoil creates low pressure above the wing and relatively higher pressure below the wing. Vortex size is also affected by proximity to the ground. If youre flying low enough to be in ground effect, the vortex isnt able to fully develop.

Combining the Gweduck’s advanced hull with its counter-rotating propellers means differential power allows crosswind water taxiing impossible in floatplanes along with higher hull-in-water taxiing speeds. “We Resist pulling back, instead letting it accelerate in ground effect (or should we say water effect) for a few seconds.
