美国公布六处商用无人机测试场所The US aviation regulator has announced the six states that will host sites for testing commercial use of drones.美国航空监管部门宣布，国内六个州将可以测试使用商用无人机。 The Federal Aviation Administration (FAA) picked Alaska, Nevada, New York, North Dakota, Texas and Virginia. The sites are part of a programme to develop safety and operational rules for drones by the end of 2015. Hitherto mainly used by the military, the potential of drones is now being explored by everyone from real estate agents to farmers or delivery services. The head of the FAA, Michael Huerta, said safety would be the priority as it considers approval for unleashing the unmanned aircraft into US skies. Pilots will be notified through routine announcements about where drones are being flown. The FAA said in a statement that its decision followed a 10-month process involving proposals from 24 states. The agency said it had considered geography, climate, location of ground infrastructure, research needs, airspace use, aviation experience and risk. The sites chosen are: A set of locations proposed by the University of Alaska in seven zones with varying climates, from Hawaii to Oregon Griffiss International Airport in central New York state will test how to integrate drones into the congested north-east airspace North Dakota Department of Commerce will test the human impact of drones and also how the aircraft cope in temperate climates The state of Nevada will concentrate on standards for air traffic and drone operators Texas A&M University plans to develop safety requirements for drones and testing for airworthiness Virginia Tech university will research operational and technical areas of risk for drones
