As far as an airport has been constructed on an
artificial island in open waters, it needs runways in different directions to enable airplanes to take
off and land against the wind. The surface of such an airport therefore
requires extensive acreage. Its construction normally implicates various environmental problems.
Hence, construction
cost are out of proportion.

The Rotating Floating Airport is a platform that rotates along a fixed circulair terminal, constructed on the bottom of the sea and connected with the mainland by a tunnel metro line. The
RFA always rotates according to the wind direction, enabling airplanes to take
off and land comfortably in all wind conditions. This type of airport
just requires only two parallel runways. Constructing an airport
this way minimizes the surface required. In addition, its 'central' construction concept
enhances minimal enviromental implications. Its offcoast location also
facilitates night traffic.
