If you are planning on submitting an airport layout to Robin so that it is used to flatten terrain in the X-Plane 10 global scenery, please submit the layout to Robin no later than October 10th, 2010 (that is, 10/10/10).
If you have an incomplete but useful layout (e.g. the airport border is in place but not the taxiway signs, you can still submit it; we only consider border outlines and the pavement itself when flattening, not markings.
You do need both the border outline and all existing pavement. The reason for this is that the airport border is used to change the land class to grass, but water is only converted to land (if we have a coastline error) base on real pavement.
More info on airport layouts and how to submit data to Robin can be found here.
