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}

Cohen, Minh Truong","doi":"10.1109/DASC.2007.4391876","DOIUrl":"https://doi.org/10.1109/DASC.2007.4391876","url":null,"abstract":"Traditional six degree-of-freedom flight simulations provide a very accurate portrayal of aircraft motion allowing for many aspects of an aircraft's flight envelope, including those close to the edge of the envelope, to be accurately modeled. 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}

On the Eurocontrol-led ERASMUS1 program, we have conducted a study of the accuracy and sensitivity to disturbances of airborne Trajectory Predictions (TP). As future ATM concepts are typically based on information sharing between the air and ground, our analysis is focused on the factors that can be potentially improved by air-ground communication. For instance, ground systems may have access to the most up to date weather forecasts from the NOAA/NWS, yet have little information about the aircraft state and intent or local atmospheric conditions. Aircraft have accurate measurements of the local wind and temperature during the flight but have limited access to the latest weather forecasts. This paper analyzes the sources of errors that impact the TP performance, and the accuracy of the FMS predicted trajectory when compared against the flown trajectory. We also discuss the suitable metrics for this analysis and the potential use of shared intent data as a way to improve the ground based TP.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"6 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":"125589275","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}

With advanced tools, they can more effectively and efficiently carry out their responsibilities. MITRE/CAASD and the FAA have developed one such tool, the future traffic display, which displays future positions of air traffic. Future traffic display enables traffic managers to examine both current flight plan trajectories and the predicted results of proposed traffic flow management strategies. Evaluations conducted with the future traffic display, both in a simulation environment and in field shadow mode operations, show that traffic managers find the future traffic display useful for numerous tasks: analyzing potential problems, identifying flows involved in the problem, visualizing the effect of a proposed traffic management initiative for resolving the problem, monitoring customer-submitted preferred routes, determining whether those routes could be accommodated, and coordinating with customers and other traffic managers. After the most recent evaluations, both traffic manager and customer participants affirmed the value of future traffic display, listing it as their top priority for implementation.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"4 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":"122214834","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}

When this is done the two systems have the potential to interfere with each other and the flyability of the localizer can be impaired. In fact when two systems are located at the opposite end of the same runway, interference through mere brute force does occur. To minimize this interference FAA Order 6750.16d requires interlocks to be installed to ensure that only one ILS can radiate at a time. Usually this interlock is operated from the control tower. In Airports where there is no control tower the issue becomes a little more complicated. The intent of this paper is to analyze this interference and develop a model that can predict the effect of one system over the other. How well the receiver discriminates between the radiations of the system that are in proximity to each other depends on the receiver selectivity. The response of these receivers under the capture effect conditions will then depend on the capability of the receiver to reproduce the beat frequency waveform that results when the carrier from one system adds to the carrier from the other. Model results do indicate that the receiver capture systems do perform very well in these circumstances however a slight deviation of the aircraft from the centerline will result in excessive perturbations on course information for approaching aircraft during over flight of the opposite end localizer antenna array.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"94 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":"131635091","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}
