Drone Operations Beyond Visual Line of Sight: Safety, Speed, and Scale
FAA Part 108 is about to become a reality. Here are some thoughts on how this will benefit search and rescue operations, potential issues, and the future.
In Tuesday’s newsletter, there was a story regarding the FAA continuing to develop Part 108 regulations for routine Beyond Visual Line of Sight (BVLOS) drone operations. Yesterday morning I began considering the implications of what this means for the future of Search and Rescue. I think I covered it all.
Drone Operations Beyond Visual Line of Sight: The Promise and Challenges of FAA Part 108
The Federal Aviation Administration (FAA) is on the verge of a significant regulatory shift with the development of Part 108 (PDF), the first set of comprehensive rules designed to allow routine Beyond Visual Line of Sight (BVLOS) drone operations in the United States.
As of June 2025, the FAA is under executive order to issue a Notice of Proposed Rulemaking by July 6, 2025, with a final rule expected by January 31, 2026. These new regulations will potentially unlock a wave of commercial, public safety, and industrial applications for unmanned aerial systems (UAS), fundamentally transforming how drones are used for infrastructure inspection, package delivery (think Amazon and Walmart delivery… I’ve seen it in action here in Phoenix, AZ), and emergency response across vast distances.
BVLOS?
Let’s take a step back and put Beyond Visual Line of Sight into simple terms: this simply means the operator cannot see the drone with the naked eye, and the flight relies on technology such as GPS, onboard cameras, sensors, and real-time telemetry for navigation, situational awareness, and safety.
What Is Part 108 and Why Does It Matter?
Under current FAA drone rules (Part 107), commercial operators are generally limited to flights within the operator’s visual line of sight, with BVLOS operations only permitted through case-by-case waivers. This restriction has “stifled innovation and economic potential” (per the EO) in industries ranging from energy and agriculture to public safety and logistics. Part 108 will allow standardization and streamlining of BVLOS operations, enabling drones to fly beyond the operator’s direct line of sight under specified safety and operational conditions (i.e., SAR!).
How will (could) Part 108 advance SAR efforts in the United States?
As I alluded to above, I can think of many ways this will help SAR, but the average person doesn’t think about those kinds of things. So, here’s where I can see drone ops pushing the current boundaries (literally) for search and rescue at both the federal and state levels.
Area Coverage and Access to Remote Locations
BVLOS drones can fly far beyond the operator’s direct sight, allowing them to quickly search expansive wilderness, remote coastlines, open water, or disaster zones that would otherwise be inaccessible or time-consuming for ground teams or manned aircraft.
This capability is critical for locating missing persons in forests, mountains, deserts, or at sea, where rapid aerial reconnaissance can make the difference between life and death.
Real-Time Data and Enhanced Situational Awareness
Drones equipped with thermal cameras, high-resolution video, and other sensors can provide live feeds and detect heat signatures through smoke, fog, or darkness, helping rescuers pinpoint survivors or hazards that would be invisible to the naked eye.
Imagine if you were preparing to take off in an aircraft to search for someone at sea. Said aircraft can’t "just takeoff.” It often takes up to 45 minutes to get into the air. What if someone could send a drone ahead of an aircraft to start searching an area - this could save a significant amount of time. With onboard AI vision, there would be little left to chance if the drone did or did not see anything. ~r
Real-time data allows SAR coordinators to assess evolving situations and deploy resources more effectively, improving overall mission efficiency.
Faster Response and Reduced Risk to Personnel
With routine BVLOS approval, SAR drones can be deployed immediately—without waiting for special waivers—enabling faster response times in emergencies such as floods, wildfires, or maritime incidents.
Drones can survey dangerous or unstable environments (e.g., collapsed buildings, chemical spills, rough seas) before human teams are deployed, reducing the risk to first responders.
Scalability and Operational Efficiency
Part 108 is expected to enable Remote Operations Centers, where a single operator can oversee multiple drones simultaneously, thereby greatly expanding the reach and scalability of SAR operations.
This is especially valuable for large-scale incidents or when resources are limited, as it enables broad-area searches with fewer personnel.
Integration with Air Traffic and Safety Systems
The new rules will require advanced detect-and-avoid technology and integration with national airspace, ensuring that SAR drones can operate safely alongside manned aircraft, even in controlled or congested airspace.
This integration improves safety and reliability, making drone deployments more predictable and routine in critical missions.
Key Features of the Proposed Part 108 Regulations
Part 108 will introduce significant operational flexibility by establishing two pathways for BVLOS approvals:
Operational permits for smaller, lower-risk missions and operational certificates for large-scale, and
Complex operations such as drone delivery networks.
The rule is expected to mandate advanced safety and technology standards, including the use of detect-and-avoid (DAA) systems, robust communication links, and possibly type certification for BVLOS-capable drones. In addition, new training and certification requirements will be introduced for remote pilots, focusing on the unique challenges associated with BVLOS operations.
Airspace integration is another key feature, as Part 108 will define specific “air corridors” and procedures for incorporating drones into controlled airspace, with coordination from air traffic control as needed. The rule also aims to streamline approval processes, reducing the need for individual waivers and allowing routine BVLOS operations for certified operators and organizations.
Routine BVLOS drone operations offer several compelling advantages. They enable expanded operational reach, allowing drones to cover much larger areas, which is ideal for searching large swaths of water or wilderness, infrastructure inspection, agricultural monitoring, and search and rescue missions.
These operations also increase efficiency and cost savings by reducing the reliance on manned aircraft and ground crews, thereby lowering operational costs and boosting productivity. In emergency situations, public safety agencies can deploy drones immediately, improving situational awareness and coordination without the delays associated with regulatory clearances.
Furthermore, the rule is expected to support the growth of emerging industries such as drone delivery and remote sensing, enhancing U.S. competitiveness in the global drone market. Finally, standardized BVLOS rules will facilitate safer integration of drones into the national airspace system, supporting the coexistence of manned and unmanned aircraft.
Now What?
The introduction of FAA Part 108 regulations for routine BVLOS drone operations is a pivotal moment for the U.S. drone industry. By standardizing and streamlining BVLOS flights, the rule will unlock new opportunities for commercial, industrial, and public safety applications, driving innovation and economic growth. However, the transition also brings significant challenges, including safety, technological, regulatory, and privacy concerns that must be carefully managed to ensure the safe and responsible integration of drones into the national airspace. As the FAA finalizes Part 108, stakeholders across industries have a unique opportunity to shape the future of U.S. aviation and unlock the full potential of drone technology.
