2018.2_RAVICH_FINAL GROUNDING INNOVATION: HOW EX-ANTE PROHIBITIONS AND EX-POST ALLOWANCES IMPEDE COMMERCIAL DRONE USE Timothy M. Ravich* Unmanned aerial vehicles—”UAVs” or “drones”—are increasingly becoming a mainstream commercial phenomenon and tool for a vast range of commercial consumer, prosumer, and professional activities. Given advances in automation and miniaturization generally—and flight control stability and autopilot systems specifically—anyone can now fly in any airspace at any time by operating hand-held fixed-wing aircraft or quadcopters with little more than an ordinary smartphone or tablet. As such, sales of store-bought drones number in the millions,1 corresponding to the wide range of civil applications and value propositions that UAVs offer. Though civil drones are an attractive business investment, substantial regulatory headwinds confront the drone industry as startups endeavor to get to market and scale quickly.
