The Future of Commercial Drones

Forecast

  • As infrastructure becomes more congested over the next decade, unmanned aerial systems will be increasingly used to manage supply chains.  
  • This transition will occur in stages as regulations adapt to technology and technology adapts to regulation, making it unlikely that much-anticipated home deliveries will be among drones’ first commercial uses.
  • Automated and unmanned aerial delivery systems will face congestion and chokepoint problems of their own, mostly caused by regulation rather than physical infrastructure.

Analysis

Moving goods from one place to another isn’t always as simple as it sounds. Intricate supply chains are often needed to coordinate transit across different countries, incorporating various modes of transportation. Every so often, new technologies come along that revolutionize how we send goods to other places. In the 20th century, it was the advent of container shipping; in the 21st century, it was the rise of a global marketplace made possible by the Internet, which changed shopping behaviors in the developed world and increased the demand for rapid delivery.

Now, as existing infrastructure struggles to keep up with the rising 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.

Overcoming Regulatory Hurdles

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 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 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 regulations likely will not be finalized until late 2016 or early 2017 because of a lengthy commenting and revisions process.)

Both the U.S. airspace system and the Federal Aviation Administration that oversees it were built on the assumption that pilots control aircraft from onboard. 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, be they autonomous piloting, networked control or other advances, will be critical to making drone flight feasible in congested urban areas.

A Gradual Development Process

Since its February announcement, the FAA has been working with industry partners to test technologies that could satisfactorily overcome the discrepancies between current regulations and drones’ potential uses. To this end, six test sites have been set up across the United States, where certain companies can look for ways to address safety concerns under three specific use scenarios in a controlled environment. Those scenarios are maintaining line of sight in urban areas where bystanders are present; operating in rural areas where observers extend the operator’s “sight”; and operating in isolated areas beyond the operator’s line of sight. In May, the tests led to the first FAA-approved drone delivery when a medical clinic in rural Virginia received much-needed supplies from an unmanned aircraft. And just this week, companies conducted the first approved long-distance drone flight in the United States and began testing a new avoidance system technology that will help operators “see and avoid” obstacles even when the aircraft are far out of their visual range.
