The paper intentions are to develop a web-based questionnaire survey, coordinate responses, and make recommendations for future training. The survey focused on air forces of the North Atlantic Treaty Organization (NATO) and European Union (EU) countries, which do not necessarily have the same benchmark in terms of practical knowledge and equipment, along with a properly set program for training these skills, despite the established standards. The results of the survey provide a graphical illustration together with comments and discussion for evaluation and interpretation. The questionnaire survey responses and discussions with pilots provide a preliminary set of recommendations for the training of both current and future pilots in terms of theoretical knowledge and practical skills flight illusions and spatial disorientation (FI/SD). The results of the survey highlight the need for better cognizance of flight illusions and SD, more frequent instructions available to flying personnel, and specific situations for FI/SD awareness.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115860760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of Unmanned Aerial Vehicles (UAVs) generates a growing interest in coping with such challenges, along with new business opportunities. As a result, it is expected to see the number of drone-based applications to rise at a very fast pace, entailing new cybersecurity risks to emerge. In this paper, we propose to tackle the problem of secure communication among untrusting parties with a certificateless-group authenticated key agreement (CL-GAKA) scheme. The intent is to enable confidentiality, message integrity, and authenticity in UAV-to-UAV communication. Provisioning untrusted UAV networks with trusted communication will provide ground for further research and applications, such as collaborative cybersecurity deterrence, network extension using trusted relay nodes, collaborative mission exercise in time-critical applications, or anonymous communication for user privacy. Moreover, in order to fill the gap of technology awareness, we provide an implementation and demonstrate that the generation of a session key between two users can be performed in approximately 600ms on a Raspberry Pi 3 Model B+ system-on-chip (1.4GHz Cortex-A53). Finally, the protocol is formally evaluated with the Scyther tool.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132110874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increasing number of military and commercial UAS application, and the vulnerabilities associated with the Global Navigation Satellite Systems (GNSS), alternative self-contained navigation systems have become of more interest to the UAS community. In addition, the significant developments in the areas of lower size, weight, power and cost (SWaP-C) laser range scanners for the automotive and aerial mapping markets, the ALS has become a more mature and viable option for UAS operations. This paper extends previous work by the authors and discusses various filter mechanizations used to perform ALS-based terrain-referenced navigation in the context of performance-based navigation. It addresses the threat model of the ALS-based navigator and, thus, addresses issues related to the accuracy, availability, integrity and continuity for these methods. Finally, data collected with Ohio University's DC-3 aircraft over Athens, OH and NASA Dryden's DC-8 Flying over Reno, NV will be used to demonstrate the performance of these methods.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130018922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lack of determinism can impact safety. The normal way to separate modular software to reduce unexpected effects is to use partitioning. The software in each partition is isolated from other partitions so that partitions cannot impact each other's required behavior. When partitions share computing resources, the system architecture must provide mechanisms to enforce determinism on that sharing and the flight certification artifacts must demonstrate the reliability of that enforcement. This paper proposes an approach for analyzing the use of shared resources by partitions in an IMA system, particularly for those built around a multicore processor, as a conceptual scheme to identify all possible avenues for interpartition interference that might cause non-determinism and then to validate and verify the system isolation mechanisms to bound such interference. First, we provide background by summarizing the IMA concept, reviewing basic computer architecture principles focused on shared resources, and defining isolation (also known as partitioning or separation). Second, we highlight the key literature on partitioning. Third, we provide a taxonomy of isolation techniques. Fourth, we propose the start of a framework for analyzing shared resource interference in light of the applied isolation techniques. The paper concludes with a summary of areas for further research.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128829211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technology under study is NASA's Airspace Technology Demonstration 2 (ATD-2) system. Using high-fidelity fast-time simulations of current-day operations (including modeling of current-day operational shortfalls) and future ATD-2 operations (including the modeling of associated ATD-2 benefit mechanisms), ATD-2 benefits were projected for three major U.S. airports. Individual airport benefits were then annualized (extrapolated to full year benefits) and nationalized (extrapolated to Core-30 FAA airports), to compute total projected monetary benefits per year. FAA-recommended cost assessment approaches were applied to compute projected ATD-2 implementation costs. Finally, costs were compared against National Airspace System (NAS)-wide benefits, and a projected return on investment was calculated. Our results estimate that the ATD-2 system can provide $2.6 billion in monetary benefits nationwide over the lifecycle of the program due to significant reduction in taxi delay as well as shifting of the delays from taxi to gate. The projected ATD-2 benefits significantly outweigh the projected implementation costs. Incorporation of ATD-2 into the FAA's planned Terminal Flight Data Manager (TFDM) system deployments is estimated to improve the benefit-cost ratio of the TFDM program from an earlier estimated 1.09 to 1.89 over the lifecycle of the program.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131660415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the problem is to minimize the makespan (landing completion time) of a given set of eVTOLs, which is equivalent to maximizing the arrival throughput. The landing order (sequence) and makespan of the mixed fleet is optimized using a heuristic approach called insertion and local search (ILS) combined with two different scheduling methods i) mixed-integer linear programming (MILP) or ii) time-advance (TA) algorithm. Finally, sensitivity analysis is performed to see the impact of number of eVTOLs expected to land on computational times of both the algorithms. Through numerical simulations and sensitivity analysis, our algorithms demonstrated real-time scheduling capabilities for on-demand UAM arrivals, which can be used as a potential future service for UAM vertiports and terminal airspace.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115235805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure safe access for all stakeholders the Federal Aviation Administration has established regulations for hobbyist and commercial operators of UAVs, partially supplemented with concurrent guidelines for hobbyist from the Academy of Model Aeronautics. Initially, many of the regulations regarding UAVs sought to maintain current safety standards by ensuring air traffic segregation between manned and unmanned aircraft. That said, much of the ongoing regulation development has occurred without data and evidence-driven practices; regulators have based decisions without accurate knowledge of the real-world usage of UAVs. In an attempt to support ongoing regulation and policy development this initial study reports statistics regarding pilot observance of UAV regulations and guidelines when performing mapping operations. Over 168,000 UAV trajectories, representing real-world UAV mapping operations, are analyzed to determine if pilots likely maintained visualline-of-sight, and followed 400 ft altitude guidelines and airspace restrictions. While global variations are noted, UAV pilots performing mapping operations within the United States are observed to widely comply with regulations. Troubling however, the analysis indicates that the small group of UAV pilots exceeding altitude regulations are much more likely to break other regulations as well, thereby increasing the risk of interaction with manned aircraft.","PeriodicalId":405724,"journal":{"name":"2018 IEEE/AIAA 37th Digital Avionics Systems Conference (DASC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114742552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
