What requirement, if any, does the control tower or airport operator have to agree with RC aircraft flying above 400 feet within 3 miles of a airport.? Does not the airport operator have the final say as to who can fly within the controled airspace?
It is not necessarily the case that the airspace within three miles of an airport is "controlled airspace." Indeed, in most cases, if the airport has no tower, that airspace is uncontrolled up to 700 or 1200 feet above ground level, even right over the runway. Which of course doesn't mean that it would be sensible to fly RC planes there.
"Airport" covers a lot of very different places, from Chicago O'Hare to some guy with a grass strip in his back yard he flies an ultralight from. It wouldn't make much sense to give the guy with the grass strip veto power over model airplane operations within a three-mile radius. Or for anybody to be flying much more than 400 feet high near a major airport. The rules we've got now don't come close to spelling out a set of sensible requirements for all these varied situations. The AMA says it's working with the FAA to come up with stuff. Hope it works.
