Drones, or UAVs (unmanned aerial vehicles), are on display at the China's first test-flight base for civilian drones of Civil Aviation Administration of China (CAAC) in Qingpu district, Shanghai, China, 14 October 2017. The country's first test-flight base for civilian drones opened on August 31 in Shanghai. The base, located in the district of Qingpu, provides service to thousands of unmanned aerial vehicles (UAV) in a country where private drones have become very popular. Drones in China are required to fly at a height below 150 meters (490 feet) and all test flights to be monitored for safety reasons to avoid obstructing air operations. According to the Aircraft Owners and Pilots Association of China, there are over 120, 000 registered drones in the country. China has approximately 500 drone manufacturers, including DJI, controlling almost 70 percent of market share. The use of UAV, initially used in videography, for recreational purposes, security and agriculture, has expanded dramatically in recent years.
