New testing examines how emergency responders can maintain priority access to airspace as commercial drone traffic grows
As drone operations expand across the United States, managing shared airspace has become a key challenge. During the DRONERESPONDERS National Public Safety UAS Conference in Williamsburg, Virginia, on March 10, 2026, NASA researchers discussed new efforts to ensure that public safety missions maintain priority access to the skies.
DRONERESPONDERS is a global non-profit program advancing public safety UAS, counter-UAS (cUAS), and Advanced Air Mobility. The organization’s annual conference brings together public safety professionals, regulators, and technology providers to address emerging challenges in the use of drones.
In a presentation titled “Airspace Prioritization for Public Safety in UAS Operation,” NASA Research Lead Abhay AJ Borade described ongoing testing aimed at helping emergency responders operate safely and effectively in increasingly busy low-altitude airspace.
Managing Airspace in the Era of Drone Delivery
Borade explained that NASA and its partners are studying how large-scale commercial drone operations could affect shared airspace. One focus of the work is the Dallas–Fort Worth key site, where regulators and researchers are evaluating commercial drone delivery operations.
The project examines how multiple drone operators can share information and coordinate activities in the same airspace. As delivery networks grow, the number of aircraft operating at low altitude is expected to increase significantly.
Public safety agencies, however, often rely on their own communications systems and procedures. That raises a key question: what happens when an emergency response mission conflicts with commercial drone activity?
“If public safety needs to conduct a life-saving mission, the system must ensure they can operate immediately and safely,” Borade explained.
Demonstrating Airspace Priority with USS
To explore that challenge, NASA recently conducted tests with the Federal Aviation Administration and several industry partners. The demonstrations evaluated how priority airspace features within a UAS Service Supplier (USS) could help manage conflicts between different types of drone operations.
ANRA Technologies acted as the USS during the testing, while DroneSense provided software support for the demonstrations.
The tests simulated several scenarios designed to reflect real-world operations.
The first scenario examined how the system would handle high-priority public safety missions operating in airspace that also contained lower-priority commercial drone activity. The goal was to verify that emergency responders could receive immediate operational priority.
A second scenario explored what happens when two high-priority public safety agencies attempt to operate in the same airspace at the same time. Researchers studied how digital coordination tools could help resolve conflicts quickly.
The third scenario focused on dynamic missions, in which operational conditions change during a flight. Researchers evaluated whether automated systems could adapt quickly enough when missions evolve or new requirements emerge.
A live demonstration during the presentation showed how USS technology can visualize and manage these priority levels in real time.
Lessons from Early Testing
Borade said the early results were encouraging. The system successfully demonstrated how airspace priority could be assigned and managed in complex operational environments.
Still, the testing highlighted the importance of reliability.
In emergency response situations, delays can have serious consequences. Systems that manage airspace priority must therefore function almost perfectly.
“Seconds matter,” Borade said, noting that systems supporting public safety missions must operate reliably 99.9 percent of the time or better.
The testing also reinforced that priority airspace management will likely become a critical feature as drone operations continue to scale.
Integrating with Public Safety Operations
While the technical demonstrations showed promising results, Borade noted that further work remains.
One important challenge is integrating these priority features with existing public safety drone standard operating procedures (SOPs). Many agencies already operate under established workflows and communications practices.
Researchers are now studying how new airspace coordination tools can align with those existing operational models.
Another open question involves determining how many priority levels are necessary to effectively manage complex airspace environments. Too few priority levels could limit flexibility, while too many could make the system harder to manage.
Finding the right balance will be an important area of future research.
Expanding Future Testing
Looking ahead, NASA plans to expand testing and outreach efforts with additional partners. Future demonstrations may explore more complex scenarios, including operations during large-scale events.
Borade noted that situations such as major public gatherings or VIP visits could place additional stress on shared airspace systems, making them useful environments for further testing.
As drone delivery services and other commercial operations grow, ensuring that emergency responders retain immediate access to the airspace will remain a central concern.
NASA’s ongoing research is helping to define how that balance might work in practice.
By testing these systems today, researchers hope to build a foundation that allows commercial drone operations and public safety missions to safely share the skies in the years ahead.
