Amazon Says Federal Rules Apply to U.S. Deliveries by Drone, seeking to bolster its efforts to deliver products via drone, said on Tuesday that states and local communities should not be allowed to regulate unmanned aerial systems authorized by federal aviation regulators. Paul Misener, the e-commerce retailer's vice president for global public policy, said in written testimony, "Uniform federal rules must apply. Given the interstate nature of UAS operations, states and localities must not be allowed to regulate UAS that the FAA has authorized, including with respect to airspace, altitude, purpose of operations, performance and operator qualifications." Drone advocates have pressed the FAA to accommodate advanced technology in commercial drone regulations expected by the end of 2016. The current proposed rules would limit flights to daylight hours at low altitudes and within an operator's visual line of site.
