Where The Drones Are

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.

Key Takeaways:

The population of small Unmanned Aircraft Systems (UAS), or drones, is rapidly increasing, with millions now in service, primarily operating in Class G airspace below 400 feet AGL.
FAA Part 107 regulations govern commercial drone operations, setting altitude limits and outlining airspace access rules, including exceptions allowing operation 400 feet above tall structures.
While drone encounters are becoming more common, the immediate risk to manned aircraft is currently lower than from birds; the greatest danger from drones is often to people on the ground due to operator error.
Manned aircraft pilots must be aware of the "Drone Zone" (below 400-500 feet AGL and near landmarks) and enhance "see and avoid" strategies, as coexistence requires increased vigilance.

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.
