The drones—they are among us. Though not yet as prevalent as Canada geese, their number has exploded as economies of scale in manufacturing and the Moore’s law effect have resulted in both lower prices and greater capabilities with each successive generation. From an aviation safety standpoint, these are the drones you should be looking for because you are most likely to encounter them.
Understanding how drones—in FAA parlance, an unmanned aircraft system (UAS) is sometimes called a drone—are used is the first step toward avoiding an unexpected and unwanted encounter. In its recently released Part 107 regulations on commercial use of UAS, the FAA focused on small UAS, craft weighing under 55 pounds. Given their numbers and popularity, this is the class of systems with which we should be most concerned.
