The latest DJI Phantom Quadcopter actually has presets which look like they will avoid defined airspace,(at least in the US) although this appears to be able to be altered.

With a size of bigger than the average bird and a max flight ceiling of well over a thousand feet, the Phantom 2 Vision+ can pose a very real danger to aircraft of all sizes. With that in mind, DJI includes airspace restrictions in the Phantom’s firmware.
If the drone’s GPS detects that it’s within certain preset limits (starting at about five miles) of an area of controlled airspace, it begins to limit its flight ceiling, with the limit decreasing the closer one gets to an airport. Within about a mile and a half of an airport, the drone will refuse to fly altogether.
It has a 3-axis stabilised gimbal carrying a camera which records 1080 video., multiple modes apart from the normal "return to home if i'm lost" type, and looks like something I'd really like to have for filming in remote areas.
