The dismissal of sectors, however, necessitates the definition of a complete and unambiguous set of flight rules in order to regulate which aircraft has to introduce an avoidance maneuver in case of a conflict. This paper describes the research on flight rules conducted within DLR's research project on sectorless ATM and describes the developed rule set in detail. Since in a sectorless concept only one specified aircraft amongst the ones in conflict is responsible for the conflict resolution different kinds of avoidance maneuvers than nowadays are necessary. This paper specifies the avoidance maneuvers that have been developed for automatic conflict resolution by DLR's traffic simulator. In particular, vertical conflict resolution often combines horizontal and vertical avoidance to allow for inaccuracies of the vertical movement and trajectory prediction. The conflict resolutions are also offered as suggestions to the controller, who can either choose one of them or develop his or her own solution. It is debated why for short and medium-term conflict resolutions the automatically generated solutions might seem more sensible or efficient than for long-term conflict resolutions. It is explained that in long-term situations the system can be able to analyze situations more thoroughly than the controller. The discussion elaborates on possibilities to implement and apply these findings in a sectorless ATM concept.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128507333","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 benefits are achieved by allowing departures to accept delay at the gate, rather than in a long departure queue, while maintaining their position in a virtual queue. Previous work has evaluated these savings for individual airports, using simulation and data analysis. This paper extends the previous work to assess the potential impact of a queue management policy across a large number of airports. One factor often neglected in previous studies is the impact of limited gate capacity, which could limit the achievable savings at some airports. We study the effect of departure queue management on gate occupancy, and find that limited capacity imposes only a modest reduction in savings. We also evaluate the economic value of the savings offered by queue management, and find that they amount to tens of millions of dollars per year at a large airport, even before considering additional benefits such as prioritization of high-value flights and the reduction in missed passenger connections. Finally, we compare the potential benefits of departure queue management across 22 U.S. airports, using recorded surveillance data over a long period of time, covering a variety of conditions. The potential benefits of queue management will be greatest at airports where long departure queues, and long taxi-out times, are often observed. Using measurements of queue length derived from surveillance data, we quantify the benefits that may be achieved at each airport and identify those with the greatest potential savings.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"409 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122099649","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}

A significant portion of the delays are associated with operations on or near the surface of major airports. There continues to be keen interest in improving efficiency of surface operations in order to reduce delay costs. The projected growth of air traffic demand is further fueling this interest. The Tower Flight Data Manager (TFDM) initiative by the FAA is aimed at providing tools in the air traffic control tower that would aid in improving operational efficiency on the surface. This initiative seeks to provide benefits through the consolidation of legacy automation systems/displays, the coherent fusion of information from multiple external systems, and the prediction and planning of flight operations on the surface. The ability to predict and plan operations on the surface is delivered to air traffic controllers through a set of decision support tools. These tools provide decision support in the following functional areas: airport configuration, runway assignment, taxi routing, sequencing & scheduling, departure metering, and departure routing. This paper is focused on describing an implementation of these tools in a prototype of the TFDM system. This prototype system is installed at Dallas/Fort Worth airport and is undergoing operational testing. The paper provides selected results from the application of the decision support tools, as well as discussion of future enhancements to the tools.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114847629","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}

As new communication services are introduced, and as the band's spectral efficiency must be increased, a quantitative characterization of this channel will become critical for advanced wireless networking [1]. This paper describes a first step in this direction: measurement and modeling of propagation path loss in the VHF band [2]. Narrowband measurements were made in the aeronautical VHF band at Detroit Metropolitan Airport (DTW). A continuous wave (sinusoidal) signal was transmitted from existing VHF radio transmitter-receiver (RTR) sites, and a mobile receiver moved about the airport surface area in a prescribed path. Propagation path loss was computed using basic link budget analyses. Results for both line-of-sight (LOS) and non-line-of-sight (NLOS) conditions are provided using the log-distance path loss model. The mean propagation path loss exponents are found to be approximately 5.6 and 4 for NLOS and LOS regions, respectively. Results for LOS regions also correspond to the well-known “2-ray,” or “plane-earth” model.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125359310","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, the beacon code allocation process is based upon the concept of discreet beacon code assignment to each ARTCC (Air Route Traffic Control Center). This allocation process is done according to the rules published in NBCAP (National Beacon Code Assignment Plan). In this paper, the distribution of codes to the ARTCCs is presented. Also, Host data is analyzed to demonstrate the utilization of codes through the day with varying level of traffic. This analys is supposed to help identify beacon code bottlenecks in the NAS. There are two kind of bottlenecks studied: (i) ARTCCs which run out of beacon codes most frequently due to high demand/traffic. (ii) ARTCCs where maximum instances of enroute beacon code reassignment occurs due to conflict with another aircraft using the same beacon code. These kinds of beacon code reassignments are undesirable as it increases pilot/controller workload during hand-off. Five (5) months of HOST data from 1st August to 31st December 2007 is analyzed. Individual beacon code utilization statistic for each of the 20 ARTCCs in the CONUS is reported for the 5 month period. On select days for which radar track data is available, the correlation of the code utilization with the traffic level in the corresponding ARTCC is also presented. This analysis provides the foundation of exploiting the inherent structure of NAS traffic to enable a more efficient beacon code assignment, i.e. with fewer beacon code reassignments and more efficient distribution of the Beacon Codes among the ARTCCs.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117023627","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}

Using the available Internet connectivity, the carriers could offer services like Video-on-Demand (VoD), Voice-over-IP (VoIP), and gaming-on-demand within the aircraft. One of the major road blocks in implementing any of these services is the additional hardware and software requirements. Each service requires dedicated hardware resources to run appropriate software components. It is not possible to accommodate every hardware component within the aircraft due to space, power, and ventilation restrictions. Also, it is economically not viable to install and maintain hardware components for every aircraft. One solution is to use cloud computing. Cloud computing is a recent innovation that is helping the computing industry in distributed computing. Cloud computing allows the organizations to consolidate several hardware resources into one physical device. The Cloud computing concept helps organizations in reducing the overall power consumption and maintenance costs. The cloud computing concept could be extended to the Aircraft Data Network environment with every aircraft subscribing to the cloud resources to run their non mission-critical applications. In this paper, the authors explore the possibility of using cloud services for Aircraft Data Networks. The authors evaluate the performance issues involved with the aircraft mobility and dynamic resource transfer between servers when the aircraft's point-of-attachment changes. The authors predict that using cloud computing concepts would encourage many carriers to offer new services within the aircraft.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129071463","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}

However, the design and execution of HITL experiments is often very challenging and risk-prone. In our market-based Traffic Flow Management (TFM) research, we develop an approach to developing HITL simulations that leads to effective experiments that yield great results, while reducing programmatic risk. The software used for the HITL experiment is developed using the Probabilistic NAS Platform (PNP). The architecture of PNP allows software clients, representing various National Airspace System (NAS) elements, to interact with real-world NAS data provided by the PNP server. The architecture of PNP allows clients to be distributed across a network, such as the Internet. This flexibility allows HITL study participants to be located anywhere in the world, provided Internet access is available. This was a requirement for our simulation, in which participants would be participating from various locations. In addition to software risk, we also tackle user acceptance challenges. HITL experiment results can be detrimentally skewed by participants who are not fully engaged in the simulation. In this study, we incorporate a feedback solicitation process into our project planning mechanism. The development of HITL simulations, while challenging and risk-prone, can provide insights that cannot be derived from automated, fast-time simulations. The approach discussed here can lead to the rapid development of robust software that engages users and collection of useful results.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123442242","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}
