The Federal Aviation Administration (FAA) and the Transportation Security Administration (TSA) are proposing “performance-based regulations to enable the design and operation of unmanned aircraft systems (UAS) at low altitudes beyond visual line of sight (BVLOS) and for third-party services, including UAS Traffic Management (UTM), that support these operations.” Routine BVLOS operations “hold tremendous potential for railroads,” Association of American Railroads (AAR) President and CEO Ian Jefferies said following the Aug. 6 release of the Notice of Proposed Rulemaking.
