It's all about math.
Forthcoming technological advances in UAS navigational and sensory systems are expected to increase the pressure on the FAA to adapt its regulatory framework to new modes of UAS functionality that involve more indirect and/or attenuated human control. For example, we expect to see more of a push to permit the limited operation of drones controlled by remote software applications, as opposed to the direct control of a person holding a remote control device. Agricultural uses are some of the most likely immediate users of these new technologies. Another major technological leap will involve UAS operations beyond the visual line of sight (BVLOS), whether the UAS is under the control of a person or a computer. Right now, such operations are restricted and operators must apply for special waivers (under very limited circumstances) from the FAA to conduct small UAS operations beyond the Part 107 limitations. Continued advances in UAS software and sensor technology involving collision avoidance, smart navigation and BVLOS are the wave of the future.
