Hunt and published by . This book was released on 2013 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future air traffic environments have the potential to exceed human operator capabilities. In response, air traffic control systems are being modernized to provide automated tools to overcome current-day workload limits. Highly accurate aircraft trajectory predictions are a critical element of the automated tools envisioned as part of the evolution of today's air traffic management system in the United States, known as NextGen. However, automation accuracy is limited due to the effects of external variables: "errors" such as wind forecast uncertainties. The focus of the Trajectory Prediction Uncertainty simulation at NASA Ames Research center were the effects of varied levels of accuracy on operator's tool use during a time based metering task. The simulation's environment also provided a means to examine the relationship between an operator's reliance strategy and underlying trust attitude. Operators were found to exhibit an underlying trust attitude distinct from their reliance strategies, supporting the strategic use of the Human-Automation trust scale in an air traffic control environment.

This book was released on 2018-05-31 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A piloted simulation experiment was conducted to document the trajectory errors associated with use of an airplane's Flight Management System (FMS) in conjunction with a ground-based ATC automation system, Center-TRACON Automation System (CTAS) in the terminal area. Three different arrival procedures were compared: current-day (vectors from ATC), modified (current-day with minor updates), and data link with FMS lateral navigation. Six active airline pilots flew simulated arrivals in a fixed-base simulator. The FMS-datalink procedure resulted in the smallest time and path distance errors, indicating that use of this procedure could reduce the CTAS arrival-time prediction error by about half over the current-day procedure. Significant sources of error contributing to the arrival-time error were crosstrack errors and early speed reduction in the last 2-4 miles before the final approach fix. Pilot comments were all very positive, indicating the FMS-datalink procedure was easy to understand and use, and the increased head-down time and workload did not detract from the benefit. Issues that need to be resolved before this method of operation would be ready for commercial use include development of procedures acceptable to controllers, better speed conformance monitoring, and FMS database procedures to support the approach transitions.Oseguera-Lohr, Rosa M. and Williams, David H.Langley Research CenterFLIGHT MANAGEMENT SYSTEMS; AIR TRAFFIC CONTROL; AIRCRAFT APPROACH SPACING; AIRCRAFT GUIDANCE; APPROACH CONTROL; PILOT SUPPORT SYSTEMS; NAVIGATION AIDS; ARRIVALS; AIRCRAFT PILOTS; DATA LINKS; AIRLINE OPERATIONS; AIRFIELD SURFACE MOVEMENTS; PILOT PERFORMANCE; TRAJECTORIES; ERRORS

This book was released on 1957 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this experiment six skilled radar air traffic controllers adjusted a movable target to a position judged to be one which would result in simultaneous arrival of the adjustable and standard targets at a reference. Each target trail consisted of five blips. The two aircraft were simulated as flying at different speeds, and three different traffic configurations were used. In addition, two types of simulated trails were used--one consisted of blips of constant brightness, whereas the other consisted of blips that faded in brightness in proportion to the phosphor-decay curve of the P-7 phosphor. The two major variables under study (Configurations and Types of Trails) were combined with the two minor variables (Controllers and Speed Pairs--both of which were included for purposes of replications) in a 3 x 2 x 6 x 6 factorial design, with 10 judgments in each of the 216 cells. The results were analyzed for both constant errors and variable errors. With both types of errors, there was an interaction between the two types of trails and the three configurations. Over all, the mean variable error in making the judgments required in this study was found to be of the order of 4 per cent of the distance-to-go, over and above a small amount of variability."--Abstract.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Air Traffic Management (ATM) paradigm is shifting towards a scenario where Trajectory Predictors (TP) play a key role. They rely on Aircraft Performance Models (APM), mathematical models of the performance related characteristics of aircraft. The widespread use of non-coventional take-off procedures, such as the flexible thrust method, has arose the necessity of modelling them to keep fidelity in take-off trajectory predictions. This project, carried out with Boeing Research & Technology Europe (BR&TE) and upon request of EUROCONROL, arises in response to the current lack in the APM market of a validated methodology to model reduced thrust operations. Its goal is to propose a complete and validated model to compute reduced thrust using Assumed Temperature (AT). The proposed methodology is composed by a model of AT and a thrust model properly validated for flexible thrust computations. To accomplish this goal, a new specification of the AT model that is being developed by BR&TE has been implemented, based upon a set of improvements suggested by EUROCONTROL. In order to determine a valid thrust model for flexible thrust computations, EUROCONTROL'S Base of Aricraft Data (BADA) and Aircraft Noise Performance (ANP) APMs have been validated. These validations have been carried out with different official Boeing's performance software: the Standard Take-off Analysis Software (STAS) and the Boeing Climbout Program (BCOP). As a result of the study different order polynomials that model the AT as a function of the take-off conditions have been produced. In addition, it has been concluded that ANP contains a valid thrust model for flexible thrust calculations, whereas the current version of BADA is not valid to compute thrust during the take-off phase. A first application of this method has been put into effect by developing a prototype of a Take-off Trajectory Predictor (TTP) that implements the flexible thrust model. This prototype is intended to be integrated in Boeing's trajectory computation infrastructure in the future as a take-off and landing module and needs to be improved, validated with Boeing's performance software and integrated as future work.

Available in PDF, EPUB and Kindle. Book excerpt: Since the very earliest years of aviation, it was clear that human factors were critical to the success and safety of the system. As aviation has matured, the system has become extremely complex. Bringing together the most recent human factors work in the aviation domain, Advances in Human Aspects of Aviation covers the design of aircrafts for the comfort and well being of the passenger. The book discusses strategies and guidelines for maximizing comfort, the design of aircrafts including cockpit design, and the training and work schedules for flight attendants and pilots. It is becoming increasingly important to view problems not as isolated issues that can be extracted from the system environment, but as embedded issues that can only be understood as a part of an overall system. In keeping with a system that is vast in its scope and reach, the chapters in this book cover a wide range of topics, including: Interface and operations issues from the perspectives of pilots and air traffic controllers, respectively. Specific human performance issues, studied from within the context of the air transportation system Issues related to automation and the delineation of function between automation and human within the current and future system The U.S. air traffic modernization effort, called NextGen Diverse modeling perspectives and methods Safety and ethics as driving factors for change Cognition and work overload Empirical research and evaluation of the air transportation domain As air traffic modernization efforts begin to vastly increase the capacity of the system, the issues facing engineers, scientists, and other practitioners of human factors are becoming more challenging and more critical. Reflecting road themes and trends in this field, the book documents the latest research in this area.

Download or read book The Future of Air Traffic Control written by Panel on Human Factors in Air Traffic Control Automation and published by National Academies Press. This book was released on 1998-02-09 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automation in air traffic control may increase efficiency, but it also raises questions about adequate human control over automated systems. Following on the panel's first volume on air traffic control automation, Flight to the Future (NRC, 1997), this book focuses on the interaction of pilots and air traffic controllers, with a growing network of automated functions in the airspace system. The panel offers recommendations for development of human-centered automation, addressing key areas such as providing levels of automation that are appropriate to levels of risk, examining procedures for recovery from emergencies, free flight versus ground-based authority, and more. The book explores ways in which technology can build on human strengths and compensate for human vulnerabilities, minimizing both mistrust of automation and complacency about its abilities. The panel presents an overview of emerging technologies and trends toward automation within the national airspace system--in areas such as global positioning and other aspects of surveillance, flight information provided to pilots an controllers, collision avoidance, strategic long-term planning, and systems for training and maintenance. The book examines how to achieve better integration of research and development, including the importance of user involvement in air traffic control. It also discusses how to harmonize the wide range of functions in the national airspace system, with a detailed review of the free flight initiative.
