If you want to deliver cargo by drone in the United States, the Federal Aviation Administration may have just grounded your plans. Under the recently released rules proposed by the FAA for operating non-recreational unmanned aircraft systems (UAS) under 55 pounds, delivery of packages by drone would be prohibited in the U.S. The FAA rules, as currently proposed, may be a death knell – at least in the U.S. – for projects such as the Prime Air package delivery service that Amazon has been testing for several years, as well as a similar project still in development by Google.   According to the FAA, an operator will be required to maintain visual line of sight of a small drone at all times, or have an observer maintain visual contact with the UAS. The person flying the drone is considered the operator, according to the FAA. An operator has to be at least 17-years-old, pass an aeronautical knowledge test and obtain an FAA-approved UAS operator certificate. The operator has to pass the test every two years to maintain the certificate. – See more at: http://aircargoworld.com/Air-Cargo-World-News/2015/02/new-faa-rules-prohibit-cargo-delivery-drone/7029#sthash.MA4Ur2Z1.dpuf
