This article states that "the Federal Aviation Authority bans the flying of unmanned aircraft, including hobby drones, above 400ft." This is incorrect. The 400ft "limit" is a guideline for safe separation from manned aircraft (which are generally restricted from operating below 500ft). It is true that the Advisory Circular 91-57, Model Aircraft Operating Standards (June 9, 1981) restricts operation above 400 feet, but this is document is explicitly non-binding and has never been given the force of law. A hard 400' limit was considered and rejected in both the FAA Modernization and Reform Act of 2012 and the FAA's pending Interpretation of the Special Rule for Model Aircraft. If you are interested in the details of pending U.S. legislation, I suggest following the Academy of Model Aeronautics' Government Relations blog: http://amablog.modelaircraft.org/amagov/ http://amablog.modelaircraft.org/amagov/
