ENSURING SAFE OPERATION OF DRONES The airspace over London is among the most crowded in the world and the soaring popularity of small unmanned drones has added to the congestion. 1. _____ If we want to prevent such incidents in the future, stricter enforcement of regulations and better technology are required. The scale of the problem is unknown. Sales of drones in Britain and many other countries are not counted but we know the trend is increasing. America’s Federal Aviation Administration reckons consumer sales could grow from 1.9 million in 2016 to as many as 4.3 million by 2020. Close encounters are also on the rise and many of them can potentially be hazardous. Britain’s Airprox Board, which is responsible for collecting reports, found 23 near-misses between drones and aircraft between April and November last year. Today no one is sure how much damage a drone could do to a jet airliner. 2. _____ What’s more, many of them have metal components, including lithium-ion batteries, which can explode if damaged. Rules for operating drones are meant to ensure that collisions do not happen. 3. _____ Not complying with these regulations is a criminal offence. However, rules alone will not stop accidents. Stricter control is necessary. In America, recreational users are required to register their drones online and are given an identification number for their craft. Failure to register could mean a fine of up to $250,000. Schemes to help identify drone operators are also planned in Europe. Technology can also help keep drones out of trouble. 4. _____ Another method is a “virtual tether”, which in effect puts a drone on an invisible leash to prevent it from flying too far from its operator. adapted from www.economist.com A. In Britain and America drones are not supposed to go higher than 150 metres and should be kept in sight by their operators at all times. B. Those the size of a large insect are probably nothing to worry about, but there are some which can weigh 20 kilos. C. But neither various rules nor the most modern technology will stop those intent on deliberately causing harm. D. Some drone-makers are restricting the speed drones can reach, as well as installing software which programs a drone’s GPS to prevent flights near airports or nuclear power stations. E. As a result, there have been many close encounters between drones and planes and one minor collision, thankfully with negligible damage. 1. 2. 3. 4.
