An unmanned aircraft system (UAS), sometimes called a drone, is an aircraft without a human pilot onboard – instead, the UAS is controlled from an operator on the ground. UAS offer great promise for a variety of applications in many areas of life and commerce, including opportunities for use by entrepreneurs and companies that rely on aviation as part of doing business. This is why NBAA remains deeply engaged in a number of UAS rulemaking committees, as well as the RTCA drone advisory subcommittee, working towards the development of sensible regulatory policies governing commercial UAS operations.
