Drones: FAA Should Improve Its Approach to Integrating Drones into the National Airspace System
Fast Facts
The Federal Aviation Administration (FAA) is responsible for safely integrating drones into the national airspace—a complex network that includes airports, aircraft, and air traffic control facilities.
FAA has developed various planning documents to manage its efforts to integrate drones. But, it has yet to develop a comprehensive strategy to guide these efforts. For example, FAA's documents don't include important elements—such as goals, objectives, and milestones—that would help FAA manage more effectively.
We recommended that FAA develop a comprehensive strategy to integrate drones into the national airspace.
Highlights
What GAO Found
The Federal Aviation Administration (FAA) is responsible for safely integrating drones into the national airspace system—a complex network that includes airports, aircraft, and air traffic control facilities. FAA has developed various planning documents to manage its drone integration efforts but has not developed a comprehensive strategy. GAO found that FAA's documents partially include four of the seven elements of a comprehensive strategy but do not include the remaining three elements. For example, FAA's documents describe activities that are completed, under way, and planned. However, the documents do not identify drone integration goals and objectives and partially include milestones and performance measures for all activities. FAA officials stated they are developing a drone integration strategy. However, the strategy's release has been delayed multiple times, and whether the strategy will provide a comprehensive approach is unclear. Establishing a strategy with all key elements is critical to FAA's ability to effectively manage its drone integration efforts.
FAA has not clearly communicated: how drone operators' requests to conduct advanced operations can meet specific requirements or what is FAA's process for reviewing and approving those requests. Currently, drone operators seeking to conduct advanced operations not allowed under existing rules must submit operational requests by applying for waivers or exemptions to conduct these operations (see example in fig.). However, more than half of 15 industry stakeholders told GAO that FAA has not clearly communicated the requirements it looks for when reviewing and approving advanced operations. As a result, they faced challenges working with multiple FAA offices on these requests. For example, stakeholders said they experienced lengthy reviews of their requests, and at times received conflicting information from different FAA offices. FAA officials said that they recognize that their process for reviewing operational requests is complex and that they plan to take steps to improve FAA's guidance. By more clearly communicating how to satisfy FAA's requirements and FAA's process for reviewing operational requests, applicants could be better positioned to provide FAA with the quality information needed to assess these requests.
Drone Operations Allowed under Part 107 Regulations and with a Waiver
aPilots may fly at night if they have completed an initial knowledge test or training under 14 C.F.R. § 107.65 after April 6, 2021. In addition, the drone must have lighted anti-collision lighting visible for at least 3 statute miles that has a flash rate sufficient to avoid a collision. 14 C.F.R. § 107.29.
Why GAO Did This Study
Drones can provide significant social and economic benefits. For example, drones can be used to inspect infrastructure, aid in disaster and wildfire response, and deliver medical supplies.
GAO was asked to review FAA's efforts to integrate drones into the national airspace system. This report examines, among other issues, the extent to which: (1) FAA's approach to managing its drone integration efforts is consistent with key elements for a comprehensive strategy and (2) FAA has clearly communicated its requirements and process for reviewing and approving operational requests.
GAO analyzed FAA's planning documents and reports. GAO interviewed FAA officials, eight participants in one of FAA's pilot programs, and 15 industry groups, representing manufacturers, operators, and others. GAO selected industry stakeholders due to their participation in FAA pilot programs and rulemaking advisory committees, among other factors.
Recommendations
GAO is making four recommendations, including that FAA: (1) develop a drone integration strategy that includes all elements of a comprehensive strategy and (2) evaluate its current documentation to identify options to more clearly communicate how applicants can satisfy drone operational request requirements and FAA's process for reviewing and approving operational requests. FAA concurred with GAO's recommendations.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Federal Aviation Administration |
Priority Rec.
The Administrator of FAA should develop a drone integration strategy that includes all seven elements of a comprehensive strategy. (Recommendation 1) |
DOT agreed with this recommendation. In April 2024, FAA provided us with their drone integration strategy. The drone strategy includes five of the seven elements of a comprehensive strategy but do not include the remaining two elements. Specifically, the strategy does not describe (1) activities, milestones, and performance measures, or (2) resources and investments that would be required to achieve the agency's goals. In July 2024, FAA officials told us that FAA's individual lines of business and staff offices are developing business plans that will including information about activities, milestones, performance measures, and resources and investment needs. FAA officials stated that these plans will be updated on an annual basis, and will be released later this year. We will review these plans when they are completed.
|
| Federal Aviation Administration | The Administrator of FAA should evaluate its current documentation to identify options to more clearly communicate how applicants can satisfy drone operational request requirements, and communicate FAA's internal process for reviewing and approving operational requests. (Recommendation 2) |
DOT agreed with this recommendation. In July 2024, FAA reported to us that it had completed a review of its current public communications that describe how applicants can satisfy FAA drone operational request requirements. As part of its review, FAA reviewed and updated its website guidance related to part 107 waiver requests. FAA is also developing a video that will provide applicants with additional information about requirements that applicants must meet to receive a Part 107 waiver. FAA officials stated that at this time, they do not have plans to provide more detailed guidance related to conducting beyond visual-line-of-sight operations until a final regulation is completed. We will continue to monitor FAA's efforts regarding this recommendation.
|
| Federal Aviation Administration | The Administrator of FAA should develop and document a formal lessons-learned process for its drone integration activities that includes all six key practices for a lessons-learned process. (Recommendation 3) |
DOT agreed with this recommendation. In January 2024, FAA reported to us that it is currently developing a lessons learned process that will be applied to all future drone integration activities, including Part 107 waiver reviews and the BEYOND program. FAA plans to incorporate this lessons learned process in its Drone Integration Strategy. We will continue to monitor FAA's efforts regarding this recommendation.
|
| Federal Aviation Administration | The Administrator of FAA should implement the formal lessonslearned process it develops for its ongoing drone integration activities, including Part 107 waiver reviews and the BEYOND program. (Recommendation 4) |
In July 2024, FAA reported to us that it had developed a documented lessons learned process that includes all six key practices for a lessons-learned process. This process will be implemented across all FAA lines of business that have a role in implementing drone integration activities, including Part 107 waiver reviews and the BEYOND program. FAA officials stated that they began collecting data and information and analyzing this information to identify lessons learned. FAA will need to validate, document, share and apply these lessons learned to drone activities to fully implement this recommendation. We will continue to monitor FAA's efforts regarding this recommendation.
