As infrastructure struggles to keep up with the congestion that comes with growing demand, new technological developments are on the horizon that could help relieve some of that burden and improve the efficiency of global supply chains. Within the next five years, drones could become widely used to help transport goods. But rapid advancement and keen industry interest aside, the realities of regulation and technological constraints will limit the role of drones in delivering goods to customers in the United States, at least in the short term.
In 2012 the U.S. Congress instructed the Secretary of Transportation to "establish requirements for the safe operation of [unmanned] aircraft systems in the national airspace system." Three years later, the Federal Aviation Administration (FAA) responded by releasing its proposed rules of operation. The 195-page document, published in February, contained both laudable and questionable stipulations, but one overarching concern received the most attention: safety.
For any new airspace regulation, the FAA is required to consider three criteria: the safety of the aircraft, the efficient use of airspace, and the protection of people and property on the ground. Based on the proposed regulations, FAA officials are going to great lengths to ensure that drones can operate safely around other aircraft and people, even when pilots are far away. The new rules, if passed, would require operators to keep drones within their line of sight throughout the entire flight.
The line-of-sight requirement reflects the FAA's long-standing rules on determining right-of-way in the air, which mandate that operators stay vigilant "so as to see and avoid other aircraft." In modern manned aircraft, cockpit and control tower technologies have advanced enough to enable planes to stay separated and avoid hazards without needing the pilot to maintain visual continuity. The development of technologies that provide an equal level of safety assurance will be critical to making drone flight feasible in congested urban areas.
