It is based on the Broadband-VHF (B-VHF) system recently developed for aeronautical communications in the VHF band. As conditions in the L-Band significantly differ from those in the VHF band, basic physical layer parameters had to be adapted, which in turn required a re-design of the higher layers as well. B-AMC offers air/ground (A/G) as well as direct air/air (A/A) communication capabilities without ground relay. The physical layer has been designed to coexist with other systems located in the aeronautical L-Band. The B-AMC data link layer is optimized for low latency and low duty cycle data communication. The B-AMC study is funded by EUROCONTROL.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128068589","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 next generation air transportation system (NextGen) is a response to those challenges, a quantum leap forward that integrates human operators, automation, and aircraft within a net-centric and collaborative environment based on precise performance-based operations and common information sharing. Performance-based ATM is a mid-term step toward NextGen that has been demonstrated in a simulation environment and shows great promise as a scalable solution that is necessary, desirable, and achievable. Performance-based ATM is a set of capabilities, validation activities, and an operational concept that is firmly aligned with the NextGen concept and represents an affordable and realistic path to its mid-term implementation. Performance-based ATM integrates advanced flight deck communications, navigation, and surveillance (CNS) capabilities with improved ground automation, procedures, and flow strategies to improve predictability and overall ATM system performance. In such an environment, time based metering is an essential element in precisely regulating traffic flows across all domains. To date, the application of time based metering in arrival airspace has been accomplished using the traffic management advisor (TMA). Time based metering is an efficient alternative to the current practice of using miles-in-trail metering and becomes particularly beneficial when strategic resolutions can be applied to problems of contention at constrained resources. The performance-based ATM concept for time based metering in part drives the need for more accurate trajectories to be used for scheduling meter times and for strategic detection of metering problems. This paper presents the time based metering concept and focuses on the en route capabilities is needed to support that concept and identifies significant issues and areas where further research is needed.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132277856","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}

System interactions are exposed to external agents in contexts from air-to-ground links to OS patches downloaded via the Internet. This is a huge amount of software with the risk of attack from distant global sites. Yet users need assurance that the software will work and not create security problems. We focus on NIST's Software Assurance Metrics And Tool Evaluation (SAMATE) project and its contribution. SAMATE is developing specifications, metrics, and automated test suites for software assurance tools. For instance, source code security analyzers can help developers produce software with fewer security flaws. They can also help identify malicious code and poor coding practices that lead to vulnerabilities. The project's publicly available reference dataset, the SRD, contains more than 1800 flawed (and fixed!) program examples to help evaluate software assurance tools and algorithms. These metrics and reference datasets help purchasers confirm tool vendors' claims. We also study the assurance impact of tool use, methods, and techniques.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123371822","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 summarizes the communications services of current ATM systems as well as their basic operational concepts. Moreover, a comparison of different spectrum ranges and communication mechanisms used in physical and data link layers of aeronautical technologies was performed.

However, this functional aspect is almost never used in applications. A great improvement over existing procedures for statistical analysis of trajectories can be obtained by explicitly considering trajectory data as functional data. Since raw functional data is by essence infinite dimensional, no computation can be made unless a finite representation has been found: all the complexity of functional data analysis is hidden in this stage. The present paper will first analyze the functional aspect of trajectories in order to extract operationally relevant quantities then will give a way of representing optimally aircraft trajectories with a finite number of parameters, allowing further processing. Applications to trajectory prediction and classification will be briefly discussed at the end.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126095402","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}

These elements include the various system processes, including data acquisition, recording, real-time data processing, as well as the underlying networking devices themselves.
