Fixed Site means any site that is "approved & documented" by the FAA. I would suspect most of those are going to be more like AMA Flying Fields rather than random parks etc but I suppose any "fixed site" can get requested to get approval once the process is matured some.Wait, so regarding fixed sites. Does that mean in Controlled AS, you will only be able to fly in these "fixed sites"? Like a dog park or drone park? Or does fixed site mean already established sites where RC pilots fly?
