However, there exists the possibility that the security measures employed can be circumvented or defeated, and that terrorists can take unauthorized control of an aircraft while in flight. If such a situation occurs, it is critical to detect the situation and to do so as soon as possible. Time is critical in these situations - the earlier the attack is detected, the more time is available to mitigate the situation. Sometimes there is an event that might be an indicator that an attack is underway. One such event is the loss of two-way radio communication with a flight under air traffic control. Monitoring for such events helps gain critical time needed for response if a hijack is occurring. However, loss of radio communication is a relatively common event - several occur each day in the National Airspace System. The vast majority of these events are not an indication of a possible hijack - they occur for other reasons. So the challenge becomes: how to differentiate between the vast majority of loss of communication events due to reasons other than an attempt to take unauthorized control of an aircraft while in flight from those that are (this is a classic \"needle in the haystack\" problem). This paper discusses a preliminary analysis of loss of radio communication events. MITRE's Center for Advanced Aviation System Analysis (CAASD) conducted this analysis to gain insight into these events which might lead to improvements in their use as an indicator of a potential security incident such as a hijack.","PeriodicalId":201010,"journal":{"name":"2008 Integrated Communications, Navigation and Surveillance Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134088227","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}

For each airport in the daily summary, we report the number of arrival and departure operations, total taxi-time, excess taxi-time, percent of known aircraft types, and the percent of complete aircraft taxi trajectories. Other data columns in the daily summary include fuel burn, fuel cost, and emissions (i.e., HC, CO, NOx), reported as total and excess quantities. A daily report is automatically generated for the airports at which Sensis Corporation currently makes recordings: ATL, BDL, CLT, DTW, IAD, MCO, MEM, MKE, ORD, PVD, SDF, SEA, and STL; this list will grow as more ASDE-X systems are fielded. Estimation of excess fuel burn and cost requires data on the aircraft type and excess taxi-time. The aircraft type determines the fuel burn rate, taken from the ICAO database; the excess taxi-time depends on a complete taxi trajectory in the movement area. The percent of known fuel burn rates ranges from 85 to 94% for the current set of airports. The percent of complete trajectories ranges from 83 to 93% for taxiing in the movement area. For validation, we have undertaken comparison of operation counts from the processing of ASDE-X data with data reported in the FAA's Aviation System Performance Metrics (ASPM) database, and have found good agreement (standard error < 1 operation). Also, we have performed some comparisons of the ASDE-X total-time estimates against the reportable quantities from the on-time performance database of the Department of Transportation (DOT) Bureau of Transportation Statistics (BTS). This analysis is performed on a per-aircraft basis by matching the tail numbers and out-off-on-in (OOOI time) events between the two data sets.","PeriodicalId":201010,"journal":{"name":"2008 Integrated Communications, Navigation and Surveillance Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124557496","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}

NextGen goals are to accommodate flight operator preferences, to the maximum extent possible, and to impose restrictions only when a real operational need exists to meet capacity, safety, security or environmental constraints. So the Air Traffic Management system should adjust airspace and other assets to satisfy forecast demand, rather than constraining demand to match available assets. The new capabilities that will be required to meet these goals will need to be developed and tested in a realistic environment to validate the expected benefits and to develop low-risk approaches to evolving today's systems to provide these new NextGen capabilities. Test beds provide a \"microcosm\" of NAS systems to incubate initial concept evaluation prior to larger-scale field trials at a desired airport area test bed or at higher density airports. The Integrated Airport project is a test bed that supports the evolution to NextGen through operational research, evaluation and demonstration of synergy among available and emerging technologies. The project will show the feasibility of accelerating the implementation of concepts and capabilities that can substantially improve the operational effectiveness of the National Airspace System (NAS) for its stakeholders.","PeriodicalId":201010,"journal":{"name":"2008 Integrated Communications, Navigation and Surveillance Conference","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124655637","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}

Searching NOTAM data based on a geographic area is a missing component in today's widely used NOTAM Web services. Geospatially enabled NOTAM Web service was implemented providing a solution for location-based searches against databases. Upon subscribing to a topic on the Enterprise Service Bus (ESB), where Airspace Volumes of Interest (AVOI) are published, client invoked the search method by passing AVOI data in possible 3 different shapes, point, cylinder, and polygon. Projecting 3D AVOI onto 2D map and executing the retrieval by employing \"point in polygon\", \"point in circle\" and \"compare points\" methods was the procedure that took place on the server side. The outcome was a number of airports with NOTAM data available. The response was passed as a SOAP message over HTTP to client. Upon receiving, NOTAM data was displayed in a tabular form as well as graphical map providing visual support. In addition, topic publishing AVOI was secured using Public Key Infrastructure (PKI), and web service was secured using Security Assertion Markup Language (SAML) token implementing Role Based Access Control (RBAC). Only those with proper keys were able to subscribe to the topic, as well as only those with credentials were allowed to invoke the web service. This implementation has been adapted to a test case where hurricane is approaching. With this test case, airmen have been informed about the threat and provided with tools to make time-critical decisions in order to determine airports at risk and possible mitigation options for reliever efforts.","PeriodicalId":201010,"journal":{"name":"2008 Integrated Communications, Navigation and Surveillance Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128383474","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 growth is expected to take an up-turn over the next 15 years. The rapid growth of IP traffic will pose a challenge to the FTI program to meet the future IP demand in a timely manner and at a minimum cost with the high levels of reliability, performance and security required for National Airspace System (NAS) services. The purpose of this paper is to quantify the expected growth in FAA IP traffic demand in the next 2 years. We also suggest consideration of a network concept, consistent with commercial Wide Area Network (WAN) enterprise practice, whereby IP traffic capacity at the trunk side of the service delivery point (SDP) can be sized less than the aggregate of all services at the port side of the SDP, resulting savings in telecommunication cost without impacting service delivery and without introducing excessive application layer delays. This concept is based on the observation that modern IP network architecture is increasingly taking advantage of WAN acceleration appliances to maximize applications delivery and minimize applications delay as opposed to simply increasing IP access capacity. Once this network concept is introduced, solutions are proposed to support FAA applications with minimum delays while economizing on network capacity requirements. Commercial off the shelf (COTS) products to perform WAN optimization such as data, transport, application and management streamlining are also discussed.","PeriodicalId":201010,"journal":{"name":"2008 Integrated Communications, Navigation and Surveillance Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126670976","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}

They share those bands with many radio-frequency (RF) emitters that expose the links to the possibility of RF interference (RFI) and resultant control link interruptions. In this analysis we quantitatively assess the potential interference levels to which such links may be subjected. We characterize unlicensed emitters in the bands of interest, and estimate the resultant aggregate RFI levels to which small UAS uplink receivers may be exposed while operating at various altitudes above representative locales within the U.S. We also analyze the potential interference impacts of licensed RF transmitters, which are far less numerous but often individually much more powerful than the unlicensed emitters. We conclude that the possibility of RFI from the two classes of emitters may degrade the reliability of UAS control links operating in these bands, especially in populated areas. However, before any firm conclusions can be drawn from our findings, it will be necessary to validate our methodology by performing field measurements of ambient power densities and uplink performance at typical small-UA altitudes in a variety of locales within U.S. airspace.","PeriodicalId":201010,"journal":{"name":"2008 Integrated Communications, Navigation and Surveillance Conference","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134173985","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}
