In November 2013, FAA released the Roadmap that describes its three- phased approach--Accommodation, Integration, and Evolution-- to facilitate incremental steps toward its goal of seamlessly integrating UAS flight in the national airspace. Under this approach, FAA's initial focus will be on safely allowing for the expanded operation of UASs by selectively accommodating some UAS use. In the integration phase, FAA plans to shift its emphasis toward integrating more UAS use once technology can support safe operations. Finally, in the evolution phase, FAA plans to focus on revising its regulations, policy, and standards based on the evolving needs of the airspace. Currently, FAA authorizes all UAS operations in the NAS--military, public (academic institutions and, federal, state, and local governments including law enforcement organizations), and civil (commercial). Federal, state, and local government agencies must apply for Certificates of while civil operators must apply for Waiver or Authorization (COA),special airworthiness certificates in the experimental category. Civil operators may also apply for an exemption, under section 333 of the 2012 Act, Special Rules for Certain Unmanned Aircraft Systems. This requires the Secretary of Transportation to determine if certain UAS may operate safely in the NAS prior to the completion of UAS rulemakings. This also gives the Secretary the authority to determine whether to allow certain UAS aircraft to operate in the NAS without an airworthiness certification. As we previously reported, research and development continue in areas related to a UAS's ability to detect and avoid other aircraft, as well as in command and control technologies and related performance and safety standards that would support greater UAS use in the national airspace. Some of this research is being conducted by DOD and NASA. Until this research matures most UAS operations will remain within visual line of sight of the UAS operator. Foreign countries are experiencing an increase in UAS use, and some have begun to allow commercial entities to fly UASs under limited circumstances. According to industry stakeholders, easier access to these countries airspace has drawn the attention of some U.S. companies that wish to test their UASs without needing to adhere to FAA's administrative requirements for flying UASs at one of the domestically located test sites, or obtaining an FAA COA. As we most recently reported in February 2014, the 2012 Act contained provisions designed to accelerate the integration of UAS into the NAS. These provisions outlined 17 date specific requirements and set deadlines for FAA to achieve safe UAS integration by September 2015 (See app. 1). While FAA has completed several of these requirements, some key ones, including the publication of the final small UAS rule, remain incomplete. As of December 2014, FAA had completed nine of the requirements, was in the process of addressing four, and had not yet made progress on four others. Some stakeholders told us in interviews that FAA's accomplishments to date are significant and were needed, but these stakeholders noted that the most important provisions of the 2012 Act have been significantly delayed or are unlikely to be achieved by the mandated dates. Both the FAA and UAS industry stakeholders have emphasized the importance of finalizing UAS regulations as unauthorized UAS operations in the national airspace continue to increase and present a safety risk to commercial and general aviation activities. Before publication of a final rule governing small UAS, FAA must first issue a Notice of Proposed Rulemaking (NPRM). As we previously reported, the small UAS rule is expected to establish operating and performance standards for a UAS weighing less than 55 pounds, operating under 400 feet, and within line of sight. FAA officials told us in November 2014 that FAA is hoping to issue the NPRM by the end of 2014 or early 2015. According to FAA, its goal is to issue the final rule 16 months after the NPRM. If this goal is met, the final rule would be issued in late 2016 or early 2017, about two years beyond the requirement of the congressional mandate. However, during the course of our ongoing work, FAA told us that it is expecting to receive tens of thousands of comments on the NPRM. The time needed to respond to such a large number of comments could further extend the time to issue a final rule. FAA officials told us that it has taken a number of steps to develop a framework to efficiently process the comments it expects to receive. Specifically, they said that FAA has a team of employees assigned to lead the effort with contractor support to track and categorize the comments as soon as they are received. According to FAA officials, the challenge of addressing comments could be somewhat mitigated if industry groups consolidated comments, thus reducing the total number of comments that FAA must be addressed while preserving content. During our ongoing work, one industry stakeholder has expressed concern that the small UAS rule may not resolve issues that are important for some commercial operations. This stakeholder expects the proposed rule to authorize operations of small UASs only within visual line of sight of the remote operator and to require the remote operator to have continuous command and control throughout the flight. According to this stakeholder, requiring UAS operators to fly only within their view would prohibit many commercial operations, including large-scale crop monitoring and delivery applications. Furthermore, they formally requested that FAA establish a new small UAS Aviation Rulemaking Committee (ARC) with the primary objective to propose safety regulations and standards for autonomous UAS operations and operations beyond visual line of sight. According to FAA, the existing UAS ARC recently formed a workgroup to study operations beyond visual line of sight in the national airspace and to specifically look at the near- and long-term issues for this technology. In November 2013, FAA completed the required 5-year Roadmap, as well as, the Comprehensive Plan for the introduction of civil UAS into the NAS. The Roadmap was to be updated annually and the second edition of the Roadmap was scheduled to be published in November 2014. Although FAA has met the congressional mandate in the 2012 Act to issue a Comprehensive Plan and Roadmap to safely accelerate integration of civil UAS into the NAS, that plan does not contain details on how it is to be implemented, and it is therefore uncertain how UASs will be safely integrated and what resources this integration will require. The UAS ARC emphasized the need for FAA to develop an implementation plan that would identify the means, necessary resources, and schedule to safely and expeditiously integrate civil UAS into the NAS. According to the UAS ARC the activities needed to safely integrate UAS include: identifying gaps in current UAS technologies, regulations, standards, policies, or procedures; developing new technologies, regulations, standards, policies, and identifying early enabling activities to advance routine UAS operations in the NAS integration, and developing guidance material, training, and certification of aircraft, enabling technologies, and airmen (pilots). FAA has met two requirements in the 2012 Act related to the test sites by setting them up and making a project operational at one location. In our 2014 testimony, we reported that in December 2013, 16 months past the deadline, FAA selected six UAS test ranges. Each of these test sites became operational, during our ongoing work, between April and August 2014, operating under an Other Transaction Agreement (OTA) with FAA. These test sites are affiliated with public entities, such as a university, and were chosen, according to FAA during our ongoing work, based on a number of factors including geography, climate, airspace use, and a proposed research portfolio that was part of the application. Each test site operator manages the test site in a way that will give access to other parties interested in using the site. According to FAA, its role is to ensure each operator sets up a safe testing environment and to provide oversight that guarantees each site operates under strict safety standards. FAA views the test sites as a location for industry to safely access the airspace. FAA told us, during our ongoing work that they expect data obtained from the users of the test ranges will contribute to the continued development of standards for the safe and routine integration of UAS. In order to fly under a COA the commercial entity leases its UAS to the public entity for operation. the research and development supporting integration. According to FAA, it cannot direct the test sites to address specific research and development issues, nor specify what data to provide FAA, other than data required by the COA. FAA officials told us that some laws may prevent the agency from directing specific test site activities without providing compensation. As a result, according to some of the test site operators we spoke to as part of our ongoing work, there is uncertainty about what research and development should be conducted to support the integration process. However, FAA states it does provide support through weekly conference calls and direct access for test sites to FAA's UAS office. This level of support requires time and resources from the FAA, but the staff believes test sites are a benefit to the integration process and worth this investment. In order to maximize the value of the six test ranges, FAA is working with MITRE Corporation (MITRE), DOD, and the test sites to define what safety, reliability, and performance data are needed and develop a framework, including procedures, for obtaining and analyzing the data. However, FAA has not yet established a time frame for developing this framework. During our ongoing work, test site operators have told us that there needs to be incentives to encourage greater UAS operations at the test sites. FAA is, however, working on providing additional flexibility to the test sites to encourage greater use by industry. Specifically, FAA is willing to train designated airworthiness representatives for each test site. These individuals could then approve UASs for a special airworthiness certificate in the experimental category for operation at the specific test site. Test site operators told us that industry has been reluctant to operate at the test sites because under the current COA process, a UAS operator has to lease its UAS to the test site, thus potentially exposing proprietary technology. With a special airworthiness certificate in the experimental category, the UAS operator would not have to lease their UAS to the test site, therefore protecting any proprietary technology. According to FAA and some test site operators, another flexibility they are working on is a broad area COA that would allow easier access to the test site's airspace for research and development. Such a COA would allow the test sites to conduct the airworthiness certification, typically performed by FAA, and then allow access to the test site's airspace. FAA has started to use the authority granted under section 333 of the 2012 Act to allow small UASs access to the national airspace for commercial purposes, after exempting them from obtaining an airworthiness certification. While FAA continues to develop a regulatory framework for integrating small UASs into the NAS these exemptions can help bridge the gap between the current state and full integration. According to FAA, this framework could provide UAS operators that wish to pursue safe and legal entry into the NAS a competitive advantage in the UAS marketplace, thus discouraging illegal operations and improving safety. During our ongoing work, FAA has granted seven section 333 exemptions for the filmmaking industry as of December 4, 2014. FAA officials told us that there were more than 140 applications waiting to be reviewed for other industries, for uses such as precision agriculture and electric power line monitoring, and more continue to arrive. (See figure 1 for examples of commercial UAS operations.) While these exemptions do allow access to the NAS, FAA must review and approve each application and this process takes time, which can affect how quickly the NAS is accessible to any given commercial applicant. According to FAA, the section 333 review process is labor intensive for its headquarters staff because most certifications typically occur in FAA field offices; however, since exemptions under section 333 are exceptions to existing regulations, this type of review typically occurs at headquarters. FAA officials stated that to help mitigate these issues, it is grouping and reviewing similar types of applications together and working to streamline the review process. While FAA is making efforts to improve and accelerate progress toward UAS integration, additional challenges remain, including in the areas of authority, resources, and potential leadership changes. As we reported in February 2014, the establishment of the UAS Integration office was a positive development because FAA assigned an Executive Manager and combined UAS-related personnel and activities from the agency's Aviation Safety Organization and Air Traffic Organization. However, some industry stakeholders we have interviewed for our ongoing work have expressed concerns about the adequacy of authority and resources that are available to the office. A UAS rulemaking working group, comprised of both government and industry officials, recently recommended that the UAS Integration Office be placed at a higher level within FAA in order to have the necessary authority and access to other FAA lines of business and offices. In addition, according to FAA officials, the Executive Manager's position may soon be vacant. Our previous work has found that complex organizational transformations involving technology, systems, and retraining key personnel--such as NextGen another FAA major initiative--require substantial leadership commitment over a sustained period. We also found that leaders must be empowered to make critical decisions and held accountable for results. Several federal agencies and private sector stakeholders have research and development efforts under way to develop technologies that are designed to allow safe and routine UAS operations. As we have previously reported, agency officials and industry experts told us that these research and development efforts cannot be completed and validated without safety, reliability, and performance standards, which have not yet been developed because of data limitations. On the federal side, the primary agencies involved with UAS integration are those also working on research and development, namely, FAA, NASA, and DOD. FAA uses multiple mechanisms--such as cooperative research and development agreements (CRDA), federally funded research and development centers (FFRDC), and OTAs (discussed earlier in this statement)--to support its research and development efforts. In support of UAS integration, FAA has signed a number of CRDAs with academic and corporate partners. For example, FAA has CRDAs with CNN and BNSF Railway to test industry-specific applications for news coverage and railroad inspection and maintenance, respectively. Other CRDAs have been signed with groups to provide operational and technical assessments, modeling, demonstrations, and simulations. Another mechanism used by FAA to generate research and development for UAS integration are FFRDCs. For example, MITRE Corporation's Center for Advanced Aviation System Development is an FFRDC supporting FAA and the UAS integration process. Specifically, MITRE has ongoing research and development supporting air traffic management for UAS detection and avoidance systems, as well as other technologies. FAA has cited many accomplishments in research and development in the past fiscal year, as we were conducting our ongoing work. According to FAA, it has made progress in areas related to detect and avoid technologies supporting ongoing work by RTCA Special Committee Other areas of focus and progress by FAA include command and 228.control, as well as operations and approval. According to FAA, progress for command and control was marked by identifying challenges for UAS operations using ground-to-ground communications. FAA also indicated, during our ongoing work, that it conducted simulations of the effects of UAS operations on air traffic management. Furthermore, in support of research and development efforts in the future, FAA solicited for bids for the development of a Center of Excellence. The Center of Excellence is expected to support academic UAS research and development for many areas including detect and avoid, and command and control technologies. FAA expects to announce the winner during fiscal year 2015. We have previously reported that NASA and DOD have extensive research and development efforts supporting integration into the NAS.NASA has a $150-million project focused on UAS integration into the NAS. NASA officials stated that the current goal of this program is to conduct research that reduces technical barriers associated with UAS integration into the NAS, including conducting simulations and flight testing to test communications requirements and aircraft separation, among other issues. DOD has research and development efforts primarily focused on airspace operations related to detect and avoid systems. However, DOD also contributes to research and development focused on certification, training, and operation of UAS. We reported in 2012 that outside the federal government, several academic and private sector companies are conducting research in support of advancing UAS integration. Research by both groups focuses on various areas such as detect and avoid technologies, sensors, and UAS materials. For example, several private sector companies have developed technologies for visual sensing and radar sensing. Academic institutions have conducted extensive research into the use of various technologies to help the maneuverability of UASs. A number of countries allow commercial UAS operations under some restrictions. A 2014 study, conducted by MITRE for FAA, revealed that Japan, Australia, United Kingdom, and Canada have progressed further than the United States with regulations supporting integration. In fact, Japan, the United Kingdom, and Canada have regulations in place allowing some small UAS operations for commercial purposes. According to this study, these countries' progress in allowing commercial access in the airspace may be attributed to differences in the complexity of their aviation environment. Our preliminary observations indicate that Japan, Australia, United Kingdom, and Canada also allow more commercial UAS operations than the United States. According to the MITRE study, the types of commercial operations allowed vary by country. For example, as of December 2014, Australia had issued over 180 UAS operating certificates to businesses engaged in aerial surveying, photography, and other lines of business. Furthermore, the agriculture industry in Japan has used UAS to apply fertilizer and pesticide for over 10 years. Several European countries have granted operating licenses to more than 1,000 operators to use UASs for safety inspections of infrastructure, such as rail tracks, or to support the agriculture industry. While UAS commercial operations can occur in other countries, there are restrictions controlling their use. For example, the MITRE study showed that several of the countries it examined require some type of certification and approval to occur before operations. Also, restrictions may require operations to remain within line of sight and below a certain altitude. In Australia, according to the MITRE study, commercial operations can occur only with UASs weighing less than 4.4 pounds. However, the rules governing UASs are not consistent worldwide, and while some countries, such as Canada, are easing restrictions on UAS operations, other countries, such as India, are increasing UAS restrictions. For our ongoing work, we spoke with representatives of the aviation authority in Canada (Transport Canada) to better understand UAS use and recently issued exemptions. In Canada, regulations governing the use of UAS have been in place since 1996. These regulations require that UAS operations apply for and receive a Special Flight Operations Certificate (SFOC). The SFOC process allows Canadian officials to review and approve UAS operations on a case-by-case basis if the risks are managed to an acceptable level. This is similar to the COA process used in the United States. As of September 2014, over 1,000 SFOCs had been approved for UAS operations this year alone. Canada issued new rules for UAS operations on November 27, 2014. Specifically, the new rules create exemptions for commercial use of small UASs weighing 2 kilograms (4.4 pounds) or less and between 2.1 kilograms to 25 kilograms (4.6 pounds to 55 pounds). UASs in these categories can commercially operate without a SFOC but must still follow operational restrictions, such as a height restriction and a requirement to operate within line of sight. Transport Canada officials told us this arrangement allows them to use scarce resources to regulate situations of relatively high risk. For example, if a small UAS is being used for photography in a rural area, this use may fall under the new criteria of not needing an SFOC, thus providing relatively easy access for commercial UAS operations. Finally, our ongoing work has found that FAA interacts with a number of international bodies in an effort to harmonize UAS integration across countries. According to FAA officials, the agency's most significant contact in Europe has been with the Joint Authorities for Rulemaking for Unmanned Systems (JARUS). JARUS is a group of experts from the National Aviation Authorities (NAAs) and the European Aviation Safety Agency. A key aim of JARUS is to develop recommended certification specifications and operational provisions, which countries can use during the approval process of a UAS. In addition, FAA participated in ICAO's UAS Study Group, an effort to harmonize standards for UAS. ICAO is the international body that, among other things, promotes harmonization in international standards. ICAO plans to release its UAS manual in March 2015, which will contain guidance about UAS integration for the states. Additional international groups that FAA interacts with in support of UAS integration include the Civil Air Navigation Services Organization, European Organization for Civil Aviation Equipment, and North Atlantic Treaty Organization. Chairman LoBiondo, Ranking Member Larsen, and Members of the Subcommittee, this completes my prepared statement. I would be pleased to respond to any questions that you may have at this time.

Summary:
UASs are aircraft that do not carry a pilot aboard, but instead operate on pre-programmed routes or are manually controlled by following commands from pilot-operated ground control stations. The FAA Modernization and Reform Act of 2012 put greater emphasis on the need to integrate UASs into the national airspace by requiring that FAA establish requirements governing them. FAA has developed a three-phased approach in its 5-year Roadmap to facilitate incremental steps toward seamless integration. However, in the absence of regulations, unauthorized UAS operations have, in some instances, compromised safety. This testimony discusses 1) progress toward meeting UAS requirements from the 2012 Act, 2) key efforts underway on research and development, and 3) how other countries have progressed in developing UAS use for commercial purposes. This testimony is based on GAO's prior work and an ongoing study examining issues related to UAS integration into the national airspace system for civil and public UAS operations. The Federal Aviation Administration (FAA) has made progress toward implementing the requirements defined in the FAA Modernization and Reform Act of 2012 (the 2012 Act). As of December 2014, FAA had completed 9 of the 17 requirements in the 2012 Act. However, key requirements, such as the final rule for small unmanned aerial systems (UAS) operations, remain incomplete. FAA officials have indicated that they are hoping to issue a Notice of Proposed Rulemaking soon, with a timeline for issuing the final rule in late 2016 or early 2017. FAA has established the test sites as required in the Act, sites that will provide data on safety and operations to support UAS integration. However, some test site operators are uncertain about what research should be done at the site, and believe incentives are needed for industry to use the test sites. As of December 4, 2014, FAA granted seven commercial exemptions to the filmmaking industry allowing small UAS operations in the airspace. However, over 140 applications for exemptions were waiting to be reviewed for other commercial operations such as electric power line monitoring and precision agriculture. Previously, GAO reported that several federal agencies and private sector stakeholders have research and development efforts under way focusing on technologies to allow safe and routine UAS operations. During GAO's ongoing work, FAA has cited many accomplishments in research and development in the past fiscal year in areas such as detect and avoid, and command and control. Other federal agencies also have extensive research and development efforts supporting safe UAS integration, such as a National Aeronautics and Space Administration (NASA) project to provide research that will reduce technical barriers associated with UAS integration. Academic and private sector companies have researched multiple areas related to UAS integration. GAO's ongoing work found that other countries have progressed with UAS integration and allow limited commercial use. A 2014 MITRE study found that Japan, Australia, the United Kingdom, and Canada have progressed further than the United States with regulations that support commercial UAS operations. For example, as of December 2014, Australia had issued 180 UAS operating certificates to businesses in industries including aerial surveying and photography. In addition, Canada recently issued new regulations exempting commercial operations of small UASs weighing 25 kilograms (55 lbs.) or less from receiving special approval.
