This looks reasonable. A 25Kg drone is a serious threat to aircraft, and, reasonably enough, the FAA wants to make drone operators take a test and get a license. UAVs in these classes have to be operated line of sight from the ground operator and under 500 ft AGL, and only in class G (uncontrolled, usually below 1200 feet) airspace.

There's a comment that "operations in Class B, C, D and E airspace are allowed with the required ATC permission." What that basically means is no drones anywhere near an airport, where class B, C, and D airspace goes all the way down to the ground and a drone under 500 feet might be in the way.

"Near an airport" covers a lot of territory near major airports. See "http://skyvector.com/". Wide blue lines show airspace boundaries. Where you see 100/SFC, that means the controlled area is from 10,000 feet to the surface. Big chunks of metropolitan areas are thus no-drone areas.

If you really need to operate a drone in controlled airspace, it's going to require all the usual procedures for flying in controlled airspace - a flight plan, radio contact with ATC, and probably a transponder so the controllers can see the drone on radar. Sagetech has a 100 gram transponder for UAVs which identifies a drone to ATC radar, just like larger aircraft. So when your drone is taking pictures of a building, ATC can see that it's at 250 feet, sending the ID they issued you with the flight plan, and nowhere near a runway approach. They're in contact with you if they need you to move the drone. This is a lot like helicopter operations in urban areas. This will cover the needs of movie companies, bridge inspectors, and such.

There's a proposal for comment mentioned for a 2Kg "microUAV" class with less regulation. That's useful, and will encourage toy manufacturers to stay below that weight limit.

None of this allows flying drones beyond visual range. The FAA isn't taking on that problem for now.
