摘要

Drone, remotely piloted vehicle (RPV), remotely piloted aircraft (RPA), remotely operated aircraft (ROA), Unmanned Aerial Vehicles (UAV), or Unmanned Aircraft Systems refer to aircraft without a human pilot on board. UAVs have three main classes based upon the weight - light, medium and heavy. There is a flight altitude restriction of 400 feet for light 10,000 feet for medium and 18,000 feet max for non-military UAV.
