This paper presents the results of a computer simulation of the NASA Autonomous Flight Rules (AFR) concept for airborne self-separation in airspace shared with conventional Instrument Flight Rules (IFR) traffic. This study was designed to determine the impact of varying levels of intent information from IFR aircraft on the performance of AFR conflict detection and resolution. The study used Automatic Dependent Surveillance-Broadcast (ADS-B) to supply IFR intent, but other methods such as an uplink from a ground-based System Wide Information Management (SWIM) network could alternatively supply this information. The independent variables of the study consist of the number of ADS-B trajectory change reports broadcast by IFR aircraft and the time interval between those reports. The conflict detection and resolution metrics include: the number of conflicts and losses of separation, the average conflict warning time, and the amount of time spent in strategic vs. tactical flight modes (i.e., whether the autoflight system was decoupled from the planned route in the Flight Management System in order to respond to a short-notice traffic conflict). The results show a measurable benefit of broadcasting IFR intent vs. relying on state-only broadcasts. The results of this study will inform ongoing separation assurance research and FAA NextGen design decisions for the sharing of trajectory intent information in the National Airspace System.

Air traffic management (ATM) services are migrating towards a global seamless concept. This requires new thinking not only on the necessary operational changes but also on the technological paradigms that determine our current service architectures. Driven by the availability of more and more bandwidth within wide area ground networks new technologies are emerging such as Cloud Computing. Beyond that, operational concepts of FAA's NEXTGEN and Europe's SESAR include dynamically moving the responsibility for airspace blocks from one facility to another, and ensuring continuity of operation by providing contingency operations. This contribution assesses the applicability of cloud computing in ATM, and the key differences to existing commercial applications. It presents the technical cloud computing elements necessary to achieve a truly global ATM system and addresses harmonization and interoperability aspects such as standardized working procedures and controller working positions equipment for air traffic controllers. Situational awareness is key for the decision making process of controllers and pilots in NEXTGEN. A key element different to commercial cloud applications is the necessity to communicate with aircraft and pilots as cloud participants via narrowband VHF radio communications, SATCOM, or other wireless communications technologies. Situational awareness of these participants is paramount which, in the current system, is automatically provided due to the broadcast nature of voice transmissions from controllers and pilots that can be received and heard by all listeners on a particular frequency nearly simultaneously (propagation delay of the radio signal not considered). To efficiently manage the access to this shared media and limit the access only to “relevant” participants, the concept of ATC sector within a geographical area, with boundaries (horizontal and vertical) aligned with traffic patterns exists today. This paper describes mechanisms that demonstrate how SATCOM, VHF, and various data link technologies can be integrated into a service cloud by virtualizing the sector concept and relaxing or completely removing the dependence on the underlying communications media. The advantage of this concept is that sectors can be dynamically defined based on operational ATM service needs without having to adhere to the coverage limitations of the underlying telecommunications service. The current ATM system is severely limited by the underlying telecommunications service models, most often by programmatic and contractual issues rather than their technical nature. We introduce the concept of a multi-point service within a virtual sector taking into consideration operational NEXTGEN issues and demands related to capacity, performance, and global coverage. Finally we introduce a new communications service model where selected parts of the infrastructure can be selectively and partially outsourced to certified service providers. This concept allo

This paper describes Internal Research and Development (IR&D) work in progress that is being performed by Boeing Advanced Air Traffic Management (AATM) and IBM. Boeing and IBM are implementing a service that records, retrieves, analyzes and visualizes patterns using aviation data. The initial implementation is based on aircraft surveillance data. Boeing AATM has been receiving live Aircraft Situation Display to Industry (ASDI) data and archiving it for over two years. At the present time, there is not an easy mechanism to perform analytics on the data. The incoming data is large, compressed, and requires correlation with other flight data before it can be analyzed. The service exposes this data once it has been uncompressed, correlated, and stored in a database for further analysis using a variety of descriptive, predictive, and possibly prescriptive analytics tools. The service is being built partially in response to requests from Boeing Commercial Aviation for analysis of capacity and flow in the US National Airspace System. The service utilizes IBM Warehouse with DB2, WebSphere Message Broker, XML Shredding, and will be used with IBM analytics products. This paper describes the service implementation and the value it adds to the aviation domain.

New flight deck-based applications of Automatic Dependent Surveillance-Broadcast (ADS-B) offer the potential to meet improved critical safety and economic targets for airport surface operations. Specifically, standards for ADS-B applications have been developed [1] to reduce and prevent runway collisions between aircraft on the airport surface using flight deck equipment. Such applications require surveillance information with position accuracy ranging between 10 to 30 meters 95 percent of the time. Global Positioning System (GPS) information without Wide Area Augmentation System (WAAS) provides sufficient position accuracy under most conditions; however, significant solar flare activities can change the ionization characteristics of the upper layers of the atmosphere which alters GPS signal propagation resulting in decreased position accuracy, potentially making the information unusable for ADS-B surface applications. This paper describes the results of an analysis of the impact of ionospheric disturbances on the position accuracy of a single frequency GPS receiver under a range of assumed operational conditions. The results are expected to be useful for an assessment of single frequency GPS technology for ADS-B surface applications and to help identify mitigations. The analysis assumes a nominal GPS constellation as defined in the GPS Standard Positioning Service (SPS) Performance Standards (PS) and a set of GPS receiver errors models. These include tropospheric, multi-path, and receiver noise error models, which are either adopted by the GPS WAAS aviation receiver performance standard or shown in open literature as representative of actual GPS receiver errors. Interference errors are assumed to be zero and interference risks are assumed to have been mitigated by airport operation authorities. The ionospheric errors are modeled based on the errors in actual GPS Navigation Message broadcast values under minimum, maximum, and average solar cycle activity conditions. Results show the impact of these activities on various position accuracy parameters and horizontal position, and include worst case conditions. Given the assumed models, the accuracy requirements for ADS-B surface applications were always exceeded for modern GPS receivers operating in all-in-view mode, suggesting feasibility of non-WAAS, single frequency GPS for ADS-B surface applications. The paper concludes with an outline of research needs and proposed next steps.

A nationwide aeronautical data communications network for air traffic services is being planned for en route implementation beginning in 2018. Operating the network will require tradeoffs between spectrum conservation and interference prevention. While it may not be possible to preclude radio-frequency interference entirely, it is important to keep interference levels at the lowest levels consistent with the amount of spectrum available. In this paper we describe a methodology for attaining that goal through the use of “soft” (flexible) frequency-assignment rules.

Information sharing in the digital age is essential to providing a means to communicate faster and more efficiently. In aviation and air traffic management, communication is critical to daily operational coordination. At any given time there are multiple lines of communication that exist between pilots, air traffic controllers, airline operators, and other National Airspace System (NAS) users. In response to the growing need for better information sharing capabilities, the FAA has invested in a capability called System Wide Information Management (SWIM), a part of the Next Generation Air Transportation System (NextGen). The primary focus of SWIM is to provide the right information to people when they need it. The SWIM program has been developing and implementing an information sharing infrastructure to provide data services to both internal FAA and external stakeholders. The current SWIM schedule calls for a phased deployment known as segments that build upon previously introduced capabilities and technologies. The FAA is currently in the planning and prototyping phase of segment two. While SWIM is developing and deploying new infrastructure and capabilities, research and development programs are looking at future applications of SWIM and new capabilities that can potentially assist users with getting access to better data in a more reliable manner. One example of this research and development is the Network Enabled Operations (NEO) program, which demonstrated potential future uses of SWIM in assisting in airspace coordination and traffic flow utilizing the planned segment two infrastructure. The purpose of this paper is to outline in high-level summary the deployment strategy and status of SWIM segment two and to highlight the research and development work accomplished by NEO over the past year.
