The FAA, NASA, other federal partner agencies, and industry are collaborating to explore concepts of operation, data exchange requirements, and a supporting framework to enable multiple beyond visual line-of-sight (BVLOS) drone operations at low altitude airspace (under 400 feet above ground level (AGL)) where FAA air traffic services are not provided.

Unmanned Aircraft System Traffic Management (UTM) is a "traffic management" ecosystem that is separate from, but complementary to, the FAA's Air Traffic Management (ATM) system. UTM development will ultimately identify services, roles and responsibilities, information architecture, data exchange protocols, software functions, infrastructure, and performance requirements for enabling the management of low-altitude drone operations.

UTM Vision

UTM is how airspace will be managed to enable multiple BVLOS drone operations where air traffic services are not provided.

With UTM, there will be a cooperative interaction between drone operators, service providers, and the FAA to determine and communicate real-time airspace status. The FAA will provide real-time constraints to the UAS operators, who are responsible for managing their operations safely within these constraints without receiving positive air traffic control services from the FAA. The primary means of communication and coordination between the FAA, drone operators, and other stakeholders is through a distributed network of highly automated systems via application programming interfaces (API), and not voice communications between pilots and air traffic controllers.
 

Near-Term Approval Process (NTAP) for UTM Services

The FAA Reauthorization Act of 2018, PL 115-254, Section 377, directed the FAA to develop a process to permit, authorize, or allow the use of UTM Services based on the service’s ability to maintain the safety and efficiency of the National Airspace System, including managing risks on behalf of drone operators.  In response, the UAS Integration office developed the Near-Term Approval Process (NTAP), which is intended to expedite third-party service provider approvals. The NTAP is not a certification process. Instead, it is a process by which FAA evaluates the safety mitigation value of a service, so that operators can receive safety credit for using that service when seeking waivers or exemptions. 

The NTAP team reviews UTM networked UAS Service Supplier (USS) and Supplemental Data Service Provider (SDSP) applicants that support drone operations up to 400 feet AGL. Low Altitude Authorization and Notification Capability (LAANC) USSs will continue to be managed by the FAA Air Traffic Organization, not  through NTAP.  

Selection of an NTAP Service Provider (SP) and Champion Operator (CO) involves initial discussions with the candidates and review of their proposed concept of use (CONUSE), concept of operations (CONOPS), service level agreement (SLA), requirements traceability matrix (RTM), and safety risk management (SRM) plan. Once the candidates have developed their proposal and supporting documentation, the NTAP Program Manager (and other FAA stakeholders, as necessary) will evaluate the submission to ensure the operation meets the established criteria.  

Once your submission has been determined to be eligible, the next step to participate in the NTAP program is to sign a MOA with the FAA. Contact the NTAP team at aus-utm@faa.gov for more information, or to get started. 

FAA personnel will review existing materials with the service provider using the intake criteria below. Additional materials may be needed so that the FAA can conduct a Safety Risk Management (SRM) evaluation of the service. The FAA uses the NTAP Service Evaluation Matrix to ensure that sufficient materials are provided so that the FAA can fully assess the service provider’s offering. 

UTM Operational Evaluation

In early 2023, the FAA evaluated new industry proposed UTM capabilities and standards in support of small drone operations. These capabilities and standards are needed to support increasingly complex operations, like package delivery. As these operations become more frequent and start to occur in overlapping areas, the risk of collision between drones increase, highlighting the need for a scalable approach to managing drone-to-drone interactions. 

UTM services provide a solution by enabling operators to collaboratively manage drone-to-drone collision risks. Traditional methods, like filing and reviewing Notices to Airmen (NOTAMs), are not well-suited for automated operations, particularly those operating in close proximity at high operational tempo.

The UTM Operational Evaluation (OE) is a consortium of industry operators collaborating to implement UTM by effectively managing overlapping BVLOS operations. The FAA and NASA are engaged with the consortium to safely enable routine drone operations. 

The consortium has developed a governance approach, using industry standards, that outlines how service providers and operators will share data and manage operations. It also establishes cooperative operating principles and implement mechanisms for capturing service verification through a comprehensive testing system, resulting in a national framework for UTM deployment that assures equitable access to shared airspace. 

Execution of activities signal the first near-term implementation of BVLOS operations leveraging UTM services for strategic coordination and provide the data required to expand implementation, as well as to inform rulemaking. 

The FAA has started to issue Letters of Acceptance (LOA) to companies in this consortium to safely conduct commercial drone flights without visual observers in the NAS. The LOA allows them to operate while strategically coordinating with each other using UTM.  The FAA anticipates that, as UTM mature and a common set of requirements emerge, these capabilities will be expanded to other locations across the country.

UTM Operational Evaluation FAQs:

Who will be developing the “federated network?” How will the network of USSs connect and share data?
Industry will develop USS capabilities that adhere to consensus standards, as they have in the testing environments up to this point. Connectivity and data sharing are ensured by network components such as the Discovery and Synchronization Service (DSS) and an automated test harness.

Who is allowed to participate in the operational evaluation?
Any drone operator qualified to operate BVLOS via waivers or exemptions to 14 CFR part 91, part 107, or part 135 may choose to participate. USSs and SDSPs that are recognized through the FAA’s NTAP may participate. 

Do OE operators need to be able to detect and avoid crewed aircraft?
Yes. All drone operators need a way to avoid crewed aircraft, whether they are using a USS or not. Crewed aircraft collision risk can be managed using visual observers or a technical detect and avoid (DAA) system that is evaluated by the FAA when a waiver or exemption application is processed.

Will this UTM be able to support future AAM operations?
The focus of this activity is specific to drones using distributed services. Lessons learned may be applicable to future passenger- or cargo-carrying AAM operations.

*Part 135 Operators will not be required to provide ConOps through NTAP. Part 107 operators will need to submit ConOps, among other documentation, for waiver/exemption application.
**A verified (pass) report is required to proceed to the next phase.
***These items will be addressed by the UTM Service Provider Shared Airspace and Governance Agreement in the United States (USP) for SP for the OE.
