A Free Source for US Airspace Data
I would really hesitate to speak authoritatively for the FAA. My
expectation, however, is that they will simply add the GIS format for
the SUAs to the NASR subscription. Eventually, I would expect them to
eliminate the older text-based format. I would be highly surprised if
they started talking about a royalty. There has never been any such
thing for the NASR data.
