Hi Juanvi,

In the not so far future, there will be a much inproved system to submit airport layouts. Read about it on http://developer.x-plane.com/2013/12/airport-authoring-sharing-airports/
And our scenery generation tools are in a much better shape than before, so more frequent scenery rebuilds will be possible.
