Unmanned Aircraft Systems (UAS) represent a significant potential for growth in the aerospace industry. Their use in military operations has increased exponentially in the last decade alone, requiring a corresponding increase in training airspace in the United States. In addition to military usage, UAS have the potential to fulfill a myriad of roles for both the public and private sectors. However, the use of UAS has been limited in the National Airspace System (NAS) to military and public applications and only under fairly restrictive Certificates of Authorization or Waiver (COA). The only way to truly realize the potential of UAS is to fully integrate them into the NAS. The desire to integrate UAS was recently codified into law with the 2012 FAA Modernization Act, mandating integration by specific, fairly short timelines. There are several challenges currently preventing the full integration of UAS that range from technological to procedural areas. However, the one common theme in all of these challenges is Safety. Across the literature on this topic there is no consensus on how safe UAS need to be to achieve integration, whether UAS can currently meet specified safety targets, and if not, what is the best way to achieve the safety goals. The purpose of this effort was to demonstrate a comprehensive framework for analyzing UAS integration efforts using a Target Level of Safety (TLS) approach. Using reliability tools, aircraft encounter models, and data from a wide variety of sources ranging from manned aircraft safety, explosives, falling debris and earthquake damage, the primary outcome of the effort was a better understanding of the risk to second and third party persons as a result of UAS operations in the NAS. This framework and associated models are validated using reliability and casualty data from manned aircraft operations. The framework is then applied to several relevant and specific cases to demonstrate the impact of policy decisions on UAS reliability and allowed operational areas. The supporting research and analysis can serve as a baseline for future integration analysis and decision-making efforts, and was designed to allow stakeholders and decision makers in this field to assess UAS safety, and set minimum system reliability requirements and mitigation system effectiveness standards.

This book presents, in a comprehensive way, current unmanned aviation regulation, airworthiness certification, special aircraft categories, pilot certification, federal aviation requirements, operation rules, airspace classes and regulation development models. It discusses unmanned aircraft systems levels of safety derived mathematically based on the corresponding levels for manned aviation. It provides an overview of the history and current status of UAS airworthiness and operational regulation worldwide. Existing regulations have been developed considering the need for a complete regulatory framework for UAS. It focuses on UAS safety assessment and functional requirements, achieved in terms of defining an “Equivalent Level of Safety”, or ELOS, with that of manned aviation, specifying what the ELOS requirement entails for UAS regulations. To accomplish this, the safety performance of manned aviation is first evaluated, followed by a novel model to derive reliability requirements for achieving target levels of safety (TLS) for ground impact and mid-air collision accidents.It discusses elements of a viable roadmap leading to UAS integration in to the NAS. For this second edition of the book almost all chapters include major updates and corrections. There is also a new appendix chapter.

When discussing the risk of introducing drones into the National Airspace System, it is necessary to consider the increase in risk to people in manned aircraft and on the ground as well as the various ways in which this new technology may reduce risk and save lives, sometimes in ways that cannot readily be accounted for with current safety assessment processes. This report examines the various ways that risk can be defined and applied to integrating these Unmanned Aircraft Systems (UAS) into the National Airspace System managed by the Federal Aviation Administration (FAA). It also identifies needs for additional research and developmental opportunities in this field.

Prior to 2012, unmanned aircraft systems (UAS) technology had been primarily used by the military and hobbyists, but it has more recently transitioned to broader application, including commercial and scientific applications, as well as to expanded military use. These new uses encroach on existing structures for managing the nation's airspace and present significant challenges to ensure that UASs are coordinated safely and suitably with existing manned aircraft and air traffic management systems, particularly with the National Airspace System (NAS). Of particular concern is the interaction between human pilots, operators, or controllers and increasingly automated systems. Enhanced understanding of these interactions is essential to avoid unintended consequences, especially as new technologies emerge. In order to explore these issues, the National Academies of Sciences, Engineering, and Medicine organized a 2-day workshop in January 2018. This publication summarizes the presentations and discussions from the workshop.

Government and private-sector interest is growing in unmanned aircraft systems (UAS) for use in a variety of missions such as U.S. border protection, hurricane research, law enforcement, and real estate photography. However, UAS¿s can fly only after the Federal Aviation Administration (FAA) conducts a case-by-case safety analysis. This report had these research questions: (1) What are current and potential uses and benefits of UAS¿s?; (2) What challenges exist in operating UAS¿s safely and routinely in the national airspace system?; and (3) What is the Federal government¿s response to these challenges? Includes recommendations. Illustrations.

The Federal Aviation Admin. (FAA) forecasts there will be roughly 7,500 active Unmanned Aircraft Systems (UAS) in the U.S. in 5 years. Concerned with the progress of integrating UAS into the National Airspace System (NAS), Congress established specific UAS provisions and deadlines for FAA in the FAA Modernization and Reform Act of 2012. This report shows that although FAA is taking steps to advance UAS operations, significant technological barriers remain in achieving safe integration, largely because current UAS have a limited ability to detect and avoid other air traffic. In addition, FAA has not established a regulatory framework for UAS integration and is also not effectively collecting and analyzing UAS safety data or managing its oversight of UAS operations. Furthermore, FAA is behind schedule in meeting most of the UAS-related provisions of the FAA Modernization and Reform Act, including the August 2014 milestone for issuing a final rule on small UAS operations. These delays will ultimately prevent FAA from meeting Congress's Sept. 2015 deadline for achieving safe UAS integration. Figures and tables. This is a print on demand report.

The Unmanned Aircraft Systems (UAS) Comprehensive Plan details work that has been accomplished, along with future efforts needed to achieve safe integration of UAS into the National Airspace System (NAS). Throughout Fiscal Year 2012 (FY12), work was conducted to develop elements required to create a more complete picture of achieving safe UAS integration. The perspectives and information available from these individual activities create a framework and reveal an evolving capability for the integration of UAS into the NAS.Representatives from the Next Generation Air Transportation System (NextGen) partner agencies – the Departments of Transportation (DOT), Defense (DoD), Commerce (DOC), and Homeland Security (DHS), the National Aeronautics and Space Administration (NASA), and the Federal Aviation Administration (FAA) – as well as industry representatives, provided through the FAA's UAS Aviation Rulemaking Committee (ARC), have actively participated in constructing this Plan. The completed work is a testament to the collaboration among representatives from the partner agencies and the UAS community.The continued safe integration of UAS in the NAS and increased NAS access for UAS will be driven by incremental advances in: research and development (R&D) (including test ranges); rulemaking (including operational approval and airworthiness standards); and development of UAS-related technologies. Safe integration will lead us from today's need for accommodation of UAS through individual approvals to a time when standardized/routine integration into the NextGen environment is well defined.Six high-level strategic goals that are specific, measureable, attainable, realistic, and timely were developed to reflect the principal objective of safe UAS integration into the NAS. These high-level goals – summarized below – were derived from existing goals provided by the partner agencies and should therefore resonate with the wide range of UAS stakeholders.The overarching approach for the Goals is to allow public integration to lay the framework for civil integration. The first two Goals apply to small UAS (under 55 pounds) within visual lineof- sight (VLOS), assuming the public realm would be accomplished first and civil would follow; the third and fourth Goals apply to the other UAS, with the same process: public would occur first and civil would follow. Goal 5 was established to plan and manage growing automation capabilities through research, and Goal 6 provides the opportunity for the U.S. to remain leaders in the international forum. The sum of these Goals shows a phased-in approach for UAS integration in the NAS.The UAS Comprehensive Plan sets the overarching, interagency goals, objectives, and approach to integrating UAS into the NAS. Each partner agency will work to achieve these national goals, and may develop agency-specific plans that are aligned to the national goals and objectives. The FAA's Integration of Civil UAS in the NAS Roadmap is an example of one such plan. It outlines, for planning purposes and within a broad timeline, the tasks, assumptions, dependencies, and considerations needed to enable UAS integration in the NAS within the wider UAS community. It will remain consistent with the UAS Comprehensive Plan. The FAA's UAS Concept of Operations (ConOps) reflects their desired end-state, and lays out the pathway for achieving this end-state, anticipating the technological and procedural enhancements required to make integration happen. In addition, it begins the engineering process of incorporating UAS-specific changes into the NextGen Implementation Plan.

With approval of UAS for civilian use in the National Airspace System, comes the need for formal integration. Manned and unmanned aircraft will share the same volumes of airspace, for which the safety standards must be upheld. Under manned aircraft operations, certain implicit assumptions exist that must be made explicit and translatable to the unmanned aircraft context. A formal system safety assessment approach through a fault tree analysis was used to identify assumptions contingent on a pilot's presence inside the fuselage and areas of weakness in operational equivalency of UAS.
