could be uniquely helpful. The FY2009 NASA Authorization Bill reflected the importance of UAS commercialization to Congress by calling for NASA to cooperate with other Government agencies, academia and industry in advancing UAS access to the National Airspace System (NAS).
NASA’s historical interactions with other Government agencies provided the needed framework for collaboration and coordination between NASA, the FAA (in particular), and other stakeholders in the formulation of the UAS Integration in the NAS (UAS-NAS) Project. The initial formulation work led to a deliberate focus of working towards routine access of UAS in the NAS for civil and commercial purposes. This focus helped determine the technical areas where NASA had the means and resources to assist the community. These areas were Separation Assurance and/or Collision Avoidance, which UAS-NAS addressed via the Detect and Avoid (DAA) Technical Challenge (TC); Pilot Aircraft Interface, which UAS-NAS addressed via the Human Systems Integration (HSI) team; Certification Requirements, which UAS-NAS addressed initially as a proposed activity, and eventually with the Systems Integration and Operationalization (SIO) activity; and Communications, which UAS-NAS addressed with Command and Control (C2) TC.
At the start of the project, it was recognized that research was needed to support the development of requirements and standards for DAA systems. It was acknowledged that these were necessary systems to safely integrate UAS into the NAS in compliance with FAR Part 91.113. The means were missing for electronically avoiding collisions. Also missing, was a definition of what \"well clear\" really meant for a UAS. The UAS-NAS Project provided answers to these questions. Effectively providing the bulk of the simulation and flight test data and analyses that resulted in DAA and Air-to-Air Radar (ATAR) Minimum Operational Performance Standards (MOPS). Later, the project leveraged these DAA and ATAR MOPS, and their corresponding FAA Technical Standard Orders (TSO), to demonstrate the safe compliance with 91.113 while accomplishing the No-Chase Certificate of Airworthiness Waiver (COA) or NCC demonstration.
Similarly for C2, when the project started there were no requirements or standards in place for spectrum to support UAS communications (command and control included). NASA's research directly led to the development of MOPS for Terrestrial C2, as well as FAA TSO (C-213). The Control Non-Payload Communication (CNPC) radio Version 7 developed by Collins (with help from NASA) is considered the radio that most closely meets the C2 MOPS, and the project performed testing of that radio to further update the C2 Terrestrial MOPS.
With regards to the Operational Test Environment, recognizing that new technologies need to be tested in a relevant environment that is representative of the NAS, the project developed the means to enable the safe performance of such tests. Testing in a relevant environment helps build confidence and acceptance by FAA regulators and the general public. The Live Virtual Constructive Distributed Environment (LVC-DE) was particularly useful, especially as its results were validated with flight test data.
When the project began, the FAA's business structure was not yet organized to address the integration or accommodation UAS in the NAS in a coordinated manner across their different lines of business. Close collaboration between the two agencies helped advance the FAA’s structural organization to better support the growing UAS market. The NASA/FAA UAS Integration Research Transition Team (RTT) particularly proved to be an excellent forum for focusing both NASA's and the FAA's work; while keeping executives at both Agencies aware of progress and challenges.
A most telling indicator of the project’s success was its impact in industry. When the project began, industry needed a more reliable and repeatable methodology for sustained UAS integration efforts. Standards, policies, procedures, and regulations for integrating UAS in the NAS were missing, especially to address the incorporation of the unique aspects of UAS. As a result of the UAS-NAS Project, critical MOPS and TSOs were developed and made available for industry, to the point that one of the project’s SIO partners, leveraged NASA's work, and obtained a No Chase COA approval — a first for private use of a UAS that size.
In summary, the UAS-NAS Project was fully successful at advancing the state of the art — at enabling UAS commercialization through the development of standards based on research findings validated in a relevant environment. Additionally, the UAS-NAS Project was a catalyst for increased FAA involvement, and helped advance the opportunities for industry to commercialize UAS operations at all altitude regimes.

The Integrated Aviation Systems Program (IASP) focuses on maturing and integrating NextGen technologies into major vehicle/operational systems and subsystems that will address these national challenges.
Using a system-level approach, NASA researchers explore, assess and demonstrate the benefits of those technologies in an operationally relevant environment.
By focusing on technologies that have already proven their merit at the fundamental research level, this program will help transition them more quickly to the aviation community, as well as inform future fundamental research needs. In addition, the program will focus on integrated system-level research of interest and importance to the aviation stakeholder community.
The Program synchronizes its work with the long-term, fundamental research conducted by other programs within the NASA Aeronautics portfolio, and closely coordinates with research efforts of other federal government agencies.
The Environmentally Responsible Aviation Project, the first project within IASP, began implementation in FY2010 and will continue through FY2015. The primary goal of this project is to advance vehicle concepts and technologies that can simultaneously reduce fuel burn, noise and emissions.
The second project within IASP is the Unmanned Aircraft Systems (UAS) Integration in the National Airspace System (NAS) Project. This project began implementation in FY2011 and is slated to continue through FY2015. The goal of this project is to contribute capabilities that reduce the technical barriers related to the safety and operational challenges associated with enabling routine UAS access to the NAS.
The third project within IASP is the Flight Demonstrations and Capabilities (FDC) Project. It consists of an integrated set of flight test capabilities and demonstrations and conducts complex and integrated small-scale flight research demonstrations. The FDC Project will focus on innovation and flexibility, which is consistent with the ARMD strategic plan, program/project activities, other NASA mission directorate activities, and national strategic needs.
The Integrated Aviation Systems Program (IASP), part of NASA’s Aeronautics Research Mission Directorate, focuses on the national airspace challenges of mobility, capacity, safety, security, energy and the environment. The program’s primary aim is to help with the nation’s transition to the Next Generation Air Transportation System, or NextGen, by developing technologies that can be integrated into future air vehicles and operational systems and subsystems.
IASP concentrates on proven technologies, and performs testing and validation in an operationally relevant environment. This approach helps to
transition advances more quickly to the aviation community and provides direction for future fundamental research. To enhance its relevance,
the program’s systems level research is guided by the usefulness to and the interest of key aviation stakeholders.
The work in the Integrated Aviation Systems Program (IASP) directly benefits the public by making it possible to test future aircraft designs and technologies that can someday transform aviation into an even more safe and sustainable mode of transportation. The program takes the most promising new ideas from the other ARMD research programs and tests the technologies in as real-world an environment as possible, usually through highly complex flight tests. The goals are to reduce risks associated with implementing the technologies and reduce the time it takes to transition them to the aviation community.
The Integrated Aviation Systems Program (IASP) addresses one of the most pressing challenges facing the Federal Aviation Administration – how to safely and routinely allow the access of Unmanned Aerial Systems (UAS) to the national airspace – by collecting data from flight test and simulations to inform the FAA's policies, procedures, and approval processes.
