(IAI) delivered a software tool to NASA Langley that models Merging and Spacing (M&S) for arrivals and departures in the Airspace Concepts Evaluation System (ACES) NAS-wide simulation. This delivery allows researchers to use ACES for system-level studies of the complex terminal airspace. As a precursor to use of the tool for research, the software was evaluated against current day arrivals in the Atlanta TRACON using Atlanta's Hartsfield-Jackson International Airport (KATL) arrival schedules, Standard Terminal Arrival Routes (STARs), and traffic flow management (TFM) techniques typical for Atlanta. Results of this validation effort are presented describing data sets, traffic flow assumptions and techniques, and arrival rate comparisons between reported landings at Atlanta versus simulated arrivals using the same traffic sets in ACES equipped with M&S. Since emphasis for intended research is on arrival capacity, this was also the focus of the validation. Before testing began, the simulated system was expected to demonstrate superior capacity over current day Atlanta by managing spacing intervals efficiently and exactly. Initial results, instead, showed the simulation's modeled capacity to be far short of what human controllers currently achieve, despite the efficiently managed spacing. Investigation into the cause of the shortfall revealed aspects of systems-level flow and control techniques that are critical to achieving sustained high capacity in the face of varying traffic loads and type mixes. This new understanding, once applied to the current day validation model, allowed a match of Atlanta's arrival capacity as well as a better understanding of how modern airports are limited by current day route models. Following this validation effort, a sensitivity study was conducted to measure the impact of variations in system parameters on the Atlanta airport arrival capacity.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"68 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":"114579478","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}

Klopf","doi":"10.1109/ICNSURV.2011.5935272","DOIUrl":"https://doi.org/10.1109/ICNSURV.2011.5935272","url":null,"abstract":"Air Traffic Management (ATM) has embraced the concept of System Wide Information Management (SWIM) as the means to improve data exchange between various applications in different domains such as flight data management, weather and aeronautical information management. Even though SWIM definitions in the US and Europe put emphasis at different aspects in their NextGen and SESAR (Single European Sky ATM Research) programs, the transition phase towards SWIM-enabled systems will pose similar challenges for both program initiatives. Most existing ATM systems have been designed with interfaces for specific data exchanges limited by proprietary data formats and protocols. The SWIM paradigm enables legacy systems — when adapted to new interface technologies — to be connected to new information and service users and thus impacts the life cycle of highly valuable assets. The paper outlines a stepwise approach for adaptation and evolution of systems to enable their connection to a SWIM infrastructure that follows a service-oriented architecture. We show how the models and technology selected impact the engineering of the adapters between existing legacy applications and the target infrastructure. The approach also touches nonfunctional aspects including security. Using two case studies derived from recent work with Air Navigation Service Providers (ANSPs), we discuss the evolution steps in practical examples and describe successes and pitfalls encountered so far: One case study illustrates how the system interface of the European AIS Database evolves moving from a pure JMS messaging based solution towards a service enabled approach using mainstream web services to guarantee compliance with new interoperability requirements. The second case study describes the design and development of an adapter component that connects a backend system providing VT100 interconnections for input and output streams with a SWIM message bus that completely hides all communication complexity behind XML messages. The case studies demonstrate that the system evolution process towards SWIM is driven both bottom up (from the existing applications) and top down (by standardization institutions as well as industry). Information and services provided by existing systems are valuable assets which in course of the system evolution can be maintained when properly encapsulated and hidden behind service façades. Our paper provides an outlook on the evolution towards SWIM from an ANSP's perspective as well as from an industry viewpoint. This decade will see a substantial change of the way ATM systems interact. Our approach should support decisions on how to make existing infrastructure ready for SWIM and when to launch programs to build new generation components that natively f it into the information sharing infrastructure.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"369 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":"116055256","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}

Once below visual approach minima, such dual runway operations are no longer possible. To address this loss of throughput, several concepts are currently under consideration. This paper discusses a “paired approach” concept which enables use of CSPRs down to Category I and II approach minima. The paper documents Monte Carlo analyses on the feasibility and trade-offs of paired approach procedure variants with and without an escape maneuver. It concludes that both procedure variations require echelon staggering for most airports with runway centerline (RCL) separations below 2500 ft and provides window parameters required for an acceptable Target Level of Safety (TLS). It shows that a value of up to 4000 ft for this echelon spacing is adequate for most CSPRs for an adverse wind threshold of 10 knots; the specific value depending on the concept variation and geometry. Other findings include the ability to achieve abeam positioning with an escape procedure for several runway configurations. Many procedural combinations examined are capable of pairing 95% to 100% of aircraft. Additionally, this paper presents an analysis of wake encounter risk during blunders. The analysis results suggest the non-escape procedure variant has a high probability of wake vortex encounter during blunder. On the other hand, the escape procedure variant with a delay in breakout of 8 seconds or less appears to provide protection from wake encounters even during a blunder. Preliminary considerations for surveillance requirements are presented, including optional 1090 MHz Extended Squitter (1090ES) Automatic Dependent Surveillance-Broadcast (ADS-B) messages and fields that may support the escape procedure variation.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"6 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":"124308898","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}

Iris aims at designing, developing and validating a new system for air-ground safety communications within the framework of the Single European Sky ATM Research (SESAR) Programme, to enable operational use by 2020. The system design studies are progressing in an iterative process with projects of SESAR Joint Undertaking. Overall, the general source of requirements for applications and communication performance is the FAA/Eurocontrol COCR v2 document, but several system-level requirements are not defined yet. User requirements are being defined by SESAR JU but some of them require a better understanding of their impact on the system design before a consolidation can take place. To this end, ESA studies have been analyzing the range of options for user requirements defined by aviation, and deduced the requirements for the user terminals, the characteristics required of the communication protocols, the link budget and, consequently, determined the requirements for the space segment and the ground segment. To cope with the uncertainties linked to the future operational concept and implementation of it, variation and combination of the user requirements is considered for defining “requirements options” that are further assessed and traded-off. The present Paper provides the latest results of the analysis of these requirements options, focusing on their consequences on the system design.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"11 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":"132687753","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}
