Interesting topic. To some people a drone is one a flying military aircraft that fires missiles and blows things up. I guess it depends on the context of how the question is asked. If someone asks: "What do you do for a living?" I probably wouldn't say "I fly a drone." But in context of my real estate business and how do I get my aerial photos, I would say: "I fly a drone." The government, and in my case Transport Canada has a lot of names to call a Phantom 4. It is a: sUAS, UAS, sUAV, UAV, Drone, UA, Aircraft. Not sure if they call it other things like xxxxcoptor. In describing the complete system of remote controller and aircraft, then it is a system. However when referring to the actual vehicle that is in the air it doesn't make sense to call it a system because my remote controller is not flying at 300 feet. Unfortunately this is going to be like the USB ports of computers. Good idea, but silly implementation...or is it silly implementation but a good idea. I never seem to get it right...lol I just use UAV or Drone. Easier to say and type.
