The sensors produce data at varying sampling rates and must be synchronized with each and with the aircraft state. Further, the sheer volume of data created (tens of gigabytes per run) creates analysis challenges of its own. This paper describes our solution to the data collection and analysis problem.

RVSM airspace includes discrete-event model and continuous-time model, while both the discrete-event model and continuous-time model are unable to simulate the airspace system accurately, Multi-agent based simulation can merge different types of simulation models into a combined simulation model.

This global ATM concept is central to the Joint Planning and Development Office's (JPDO) Next Generation Air Transportation System (NGATS), and underlies Europe's Single European Sky ATM Research (SESAR) initiative. The availability of timely, accurate and relevant aeronautical and meteorological information in the cockpit is critical to the safe conduct of flight and forms the basis for Air Traffic Management (ATM) decision making. The data link of aeronautical and meteorological information will facilitate the creation of a common picture of the airspace situation for all flight crews, air traffic controllers and airline operations personnel. Change notifications and timely warnings and alerts of threats to the safe and efficient conduct of flight will be enabled by these services. The ultimate goal is to provide access to on-line, real-time, quality information and weather services to any aviation user, any time, anywhere. In this framework, this paper presents the operational services and the environment of the aeronautical Information management (AIM) and meteorological (MET) data-link services envisaged to be implemented over the next decade in both Europe and USA. It reflects the concepts and system performance requirements currently developed by a joint EUROCAE (WG-76) / RTCA (SC-206) Committee. The envisaged AIM data-link services are presented: aeronautical updates both in textual and graphical form, synchronization of aeronautical data between onboard and ground systems (exchange of permanent aeronautical data regardless of AIRAC cycles). The MET data-link services are also developed : weather planning, near-term and reactive decision services.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"02 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":"121982121","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 predictive capabilities of the European ATM network will be improved with the objective of taking more strategic actions prior to departure. This process will be supported by 4D trajectory information, managed on a shared network. In this paper, we present a methodology to analyze and react to the expected traffic flows that will take advantage of this more predictive ATM network. The method consists of dynamically adapting the configuration of the sectors to the future situations by predicting not only the traffic flows but also the complexity of those flows. Currently, the traffic volume that can be managed into the sector is determined by the declared capacity or maximum number of incoming aircraft per hour. However, with the same number of incoming aircraft, the complexity of the traffic can vary over time with a significant impact to the controller's workload. Low traffic complexity can lead to situations of low cost efficiency, or other situations could lead to a degraded safety level because of an increase in the number of ATC interventions, traffic in evolution or weather conditions. The measurement of traffic complexity would allow a more efficient use of human resources by balancing workload among the operative sectors, an increase in the flexibility of the capacity management by adapting the sector boundaries to the expected situation, more efficient decisionmaking support to protect controller from overloads, and, possibly, an overall capacity gain by allowing to break free from conservative figures based on the number of aircraft per sector. These expected improvements have pushed Aena, Spain's Air Navigation Service Provider, to develop a new tool called eTLM (Enhanced Traffic Load Monitoring) to measure and react to the traffic complexity. eTLM is based on the continuous complexity that takes into consideration up-to-date data rather than historical demand. Every sector's complexity is measured in terms of the controller's workload from the present time through the next few hours by means of continuous Fast-Time Simulations of planned traffic. eTLM uses this information to dynamically adjust sector configurations to the real traffic situation. The best sectorisation is determined based on a predefined set of possible combinations, avoiding workloads higher than the maximum acceptable safety level, minimizing the number of open sectors and balancing workloads between the operative sectors. This methodology, together with the associated operational concept was validated at Aena. Several fast-time and real-time simulations were looped in order to analyze the applicability and benefits of this concept in the Spanish airspace. The first assessment was carried out by applying the current operational practices. The second step was the validation of a future operational environment with new technical enablers such as MTCD and CPDLC","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"44 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":"131317340","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 European Commission project NUP 2+3 has created a unique infrastructure that provides the networking of real-time 4D Trajectory (4DT) data created by GE Aviation's (formerly Smiths Aerospace) B737 flight management system (FMS) with air traffic management functions during revenue flights. This FMS has been modified to output and downlink an implementation of the ARINC 702A-1 \"Trajectory Bus\", making the FMS-predicted 4DT available to controllers on the ground. This provision of the aircraft 4DT to the Air Navigation Service Provider (ANSP) has enabled a set of TBOs in Sweden including 4DT-based arrival management with time-based metering to the runway threshold, application of required time of arrival (RTA) to fine-tune this arrival management, and 4DT enabled advanced-continuous descent arrivals (A-CDA), referred to as \"green approaches\" by the project. The NUP2+ project goals include facilitating the study of 4DT performance requirements, associated 4DT air/ground networking requirements and producing operational flight data to support further studies. To begin to produce such study data, a series of controlled Trajectory Evaluation Flights was conducted by the NUP2+ project in December 2006. This paper presents an overview of the motivation, objectives, experiment conduct, and preliminary data analysis of this initial set of flights. Plans for the project's expansion of these experiments are also discussed.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"574 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114049560","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}

New tactical capabilities offer the potential to increase throughput by enabling reduced separation, more effective sequencing, parallel approaches and flexible arrival and departure routes. The foundation for these tactical capabilities include advanced communication, navigation and surveillance (CNS) functions that enable control based on more closely spaced 4D trajectories enabled by aircraft with tighter Required Navigational Performance (RNP) and RNAV capabilities. Especially in weather scenarios, however, use of these tactical capabilities must be embedded in an integrated approach to managing the traffic flows providing arrivals and departures through SDO airspace. This paper focuses on the development of Collaborative Traffic Flow Management (CTFM) strategies to deliver aircraft to airports and metroplexes (groups of geographically close airports) in a manner that enables effective use of advanced tactical operations making use of Trajectory-Based Operations (TBO) -using 4D Trajectories as a basis to support closely spaced, parallel approaches and departures and the optimization of trajectories to reduce fuel consumption and minimize environmental impacts.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"15 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":"129318959","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}

In some simulations, especially those that make use of aircraft as only one contributing component of the simulation and only in normal modes of aircraft operation, it may only be necessary to approximate the general motion of aircraft. In this case it is not necessary to study the many intricate forces that act on the airplane body or to solve the associated complex dynamical equations. In this situation, six degree-of-freedom aircraft simulators may add unnecessary complexity. However, it may still be of interest to accurately model different types of aircraft uniquely in order to enable the comparison of different performance and maneuver characteristics for different aircraft in the simulation. The original, kinematics-based model detailed here uses precise flight data collected by the Federal Aviation Administration and provides a satisfactory level of fidelity for a variety of aircraft types. It is especially accurate in representing different aircraft in normal flight regimes (i.e., within the flight envelope, non-emergency, standard operations). This paper presents the general mathematical aircraft formulation, a description of both the pilot and aircraft models and parameters, and an explanation of the concept for and design of a future control system.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"171 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":"116128115","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}
