A Human in the loop (HITL) evaluation was conducted to assess flight crew acceptability of IM PA operations, procedures, and display elements within the recently updated defined roles and responsibilities, during nominal and off-nominal operations. It consisted of eight training and ten data collection scenarios simulating approaches into San Francisco International Airport. Eighteen pilots, working as flight crews, used IM information and flew flight deck-generated IM speeds to maintain an Assigned Spacing Goal relative to a Lead aircraft using one of two alternative Cockpit Display of Traffic Information implementations (comparing a minimum display implementation or a minimum implementation plus enhancements). Overall, results indicate that pilots found the IM PA operation to be acceptable and desirable. No significant differences in acceptability, workload, or performance were found based on the different display implementations or scenario nominality. Pilots were comfortable with the roles and responsibilities for the IM PA operation, where ATC monitored for separation and flight crews followed IM speeds. Pilots expressed a desire for a more salient notification of new IM Speeds. No new display features were found to be necessary for IM PA above and beyond those recommended for other IM operations. The results and recommendations were intended to be used by the Federal Aviation Administration and RTCA Special Committee 186.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116982453","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}

Currently, UAVs can perform several tasks while in flight. UAVs have real-time systems with limited capability for time-triggered synchronization, which impose synchronization limitations for their platforms. Additionally, there is no time-triggered synchronization between the UAVs and the ground station. One of the requirements for a reliable communication links between a UAV and a ground station is the need for synchronization using Global Navigation Satellite System (GNSS) in a time-triggered network. However, the information exchange between UAV and ground station lacks the time-triggered abilities. In this context, GNSS time can be used as an external source to allow UAV performing tasks connected to the ground station with time-stamped messages. In this paper, we investigate the capability of GNSS as an external time source for the time-triggered network to achieve high quality of service (QoS) of a communication link between the ground station and UAV. Simulations analysis was conducted to evaluate the overall system performance, which gives a better understanding of performance of a time-triggered wired and wireless network.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122705028","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}

Many countries worldwide are funding several researches to identify and develop enabling technologies to make urban air mobility as safe as modern aviation. One of the most critical aspect of those aeroplanes rely on the reduced fuselage dimensions and available space on board to welcome all those safety critical systems commonly used on commercial aviation. The air data system is one of the safety critical system that is equipped with several probes and vanes, protruding externally from the aircraft fuselage, and some of its functionalities are adequately redundant for general aviation and large aeroplanes. Even though an airworthiness standard applicable to urban air mobility is not ready yet, worldwide there are several efforts that will lead to type certification standards in next years. This work presents a brief survey of certified technologies available for sensing solutions feeding air data systems and solutions based on synthetic sensors certifiable in a couple of years. The survey relies on certified and certifiable innovative data sensing units for realistic urban air mobility applications. To this aim, a safety assessment analysis is presented in order to support the validity of the certifiable air data sensing solutions presented in this paper.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128432490","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}

Even though these satellites rise level of new innovations and services for consumers, lack of regulations and standards consequently brings solutions which are not so well protected. Disrupting or hacking satellite connections can have a significant effect on society or business. Previously, satellite hacking has been considered only in the context of state organized activity, however our research proofs that cheap software defined radios offers possibility to listen and attack these connections without thorough domain knowledge. Companies and governments, who operate satellites or communication links, want to ensure that confidentiality, integrity and availability are guaranteed also under exceptional conditions. However currently there is not situational awareness provided for cyber related incidents for many civil operated satellites. Therefore, this research builds awareness of attack methodology against satellite connections to build robust, security tested satellite communication solutions that are protected against the attacks and that should be able to operate in constantly evolving cyber threat matrix.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123483829","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}

This paper presents a novel airspace management approach for Urban Air Mobility (UAM) below the skyline in particular. A robust airspace discretization methodology is developed based on the expected navigation performance. Additionally, a novel methodology is developed to optimally generate airspace sectors from discrete 3D airspace cells. A preliminary verification of the novel airspace structuring methodology is performed based on navigation performance with a reference navigation architecture based on the Global Navigation Satellite System (GNSS). The proposed performance-based discretization methodology promotes operational safety and efficiency and supports enhanced UTM operators' situational awareness under dense traffic conditions. The analysis performed demonstrates that the proposed airspace model can efficiently accommodate unmanned aircraft with varying avionics equipment and can be expanded to a full Communication, Navigation and Surveillance (CNS) performance-based approach, allowing a continuous dynamic optimisation of airspace capacity.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"428 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125842918","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}
