New Rules Will Keep Unmanned Aircraft Away From Prisons and Power Plants

The rapid expansion of unmanned aircraft systems (UAS) has outpaced existing safety safeguards, prompting the FAA to codify a formal process for restricting drone flights near high‑risk sites. The proposed Unmanned Aircraft Flight Restrictions (UAFRs) stem from legislation dating back to the 2016 FAA Extension, Safety, and Security Act and its 2018 and 2024 amendments, which now explicitly include state prisons and other critical infrastructure. By establishing clear legal boundaries, the FAA aims to mitigate threats ranging from espionage over chemical plants to contraband smuggling into correctional facilities, while still supporting the burgeoning commercial drone market.

Under the new framework, a standard UAFR creates a defined polygon within a facility’s property lines, typically capping altitude at 400 feet above ground level. If a structure exceeds 300 feet, the ceiling can rise to the building’s height plus 100 feet, rounded to the nearest 50‑foot increment. A special UAFR, reserved for federal or highly sensitive sites, imposes a five‑year restriction and requires dual approval from the responsible agency and the FAA administrator. Eligibility thresholds are stringent: chemical plants must handle hazardous chemicals above set concentrations, power generators need at least 500 MW capacity, and prisons must house 500 or more inmates. Applicants must submit detailed risk analyses, traffic studies, and environmental assessments before the FAA publishes a notice for public comment.

The implications are far‑reaching. For operators, the rule delineates which drones may transit restricted zones—limited to vetted Part 91, Part 107, and future Part 108, 135, and 137 missions that broadcast remote identification. Non‑compliant flights expose pilots to civil penalties and, in national‑security cases, criminal charges. While the FAA projects $21‑$31 million in annual compliance and review expenses if 9,000 facilities adopt UAFRs, the cost is justified by the potential to avert catastrophic incidents such as explosions, toxic releases, or power outages. Ultimately, the policy provides a scalable, legally enforceable shield for America’s most vital assets while preserving the airspace needed for legitimate drone innovation.
