Riddick and published by . This book was released on 2000 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been performed on a computer code modeling an aircraft wake vortex spacing system during final approach. This code represents an intial engineering model of a system to calculate reduced approach separation criteria needed to increase airport productivity. This report evaluates model sensitivity toward various weather conditions (crosswind, crosswind variance, turbulent kinetic energy, and thermal gradient), code configurations (approach corridor option, and wake demise definition), and post-processing techniques (rounding of provided spacing values, and controller time variance).
Book Synopsis Aircraft Wake Vortex Spacing System (AVOSS) Performance Update and Validation Study by : David K. Rutishauser
Download or read book Aircraft Wake Vortex Spacing System (AVOSS) Performance Update and Validation Study written by David K. Rutishauser and published by . This book was released on 2001 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis has been performed on data generated from the two most recent field deployments of the Aircraft Wake Vortex Spacing System (AVOSS). The AVOSS provides reduced aircraft spacing criteria for wake vortex avoidance as compared to the FAA spacing applied under Instrument Flight Rules (IFR). Several field deployments culminating in a system demonstration at Dallas Fort Worth (DFW) International Airport in the summer of 2000 were successful in showing a sound operational concept and the system's potential to provide a significant benefit to airport operations. For DFW, a predicted average throughput increase of 6% was observed. This increase implies 6 or 7 more aircraft on the ground in a one-hour period for DFE operations. Several studies of performacne correlations to system configuration options, and system inputs are also reported. The studies focus on the validation performance of the system.

Download or read book A Sensitivity Study of the Aircraft Vortex Spacing System (Avoss) Wake Predictor Algorithm to the Resolution of Input Meteorological Profiles written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-21 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AVOSS project demonstrated the feasibility of applying aircraft wake vortex sensing and prediction technologies to safe aircraft spacing for single runway arrivals. On average, AVOSS provided spacing recommendations that were less than the current FAA prescribed spacing rules, resulting in a potential airport efficiency gain. Subsequent efforts have included quantifying the operational specifications for future Wake Vortex Advisory Systems (WakeVAS). In support of these efforts, each of the candidate subsystems for a WakeVAS must be specified. The specifications represent a consensus between the high-level requirements and the capabilities of the candidate technologies. This report documents the beginnings of an effort to quantify the capabilities of the AVOSS Prediction Algorithm (APA). Specifically, the APA horizontal position and circulation strength output sensitivity to the resolution of its wind and turbulence inputs is examined. The results of this analysis have implications for the requirements of the meteorological sensing and prediction systems comprising a WakeVAS implementation.

Book Synopsis Wake Turbulence by : National Research Council
Download or read book Wake Turbulence written by National Research Council and published by National Academies Press. This book was released on 2008-04-27 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Without major changes, the current air transportation system will be unable to accommodate the expected increase in demand by 2025. One proposal to address this problem is to use the Global Positioning System to enable aircraft to fly more closely spaced. This approach, however, might be limited by the wake turbulence problem, which can be a safety hazard when smaller aircraft follow relatively larger aircraft too closely. To examine how this potential hazard might be reduced, Congress in 2005 directed NASA to request a study from the NRC to assess the federal wake turbulence R&D program. This book provides a description of the problem, an assessment of the organizational challenges to addressing wake turbulence, an analysis of the technical challenges in wake turbulence, and a proposal for a wake turbulence program plan. A series of recommendations for addressing the wake turbulence challenge are also given.

Download or read book Concept to Reality written by National Aeronautics Admininstration and published by CreateSpace. This book was released on 2013-11 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Langley Memorial Aeronautical Laboratory was established in 1917 as the Nation's first civil aeronautics research laboratory under the charter of the National Advisory Committee for Aeronautics (NACA). With a primary mission to identify and solve the problems of flight, the highly productive laboratory utilized an extensive array of wind tunnels, laboratory equipment, and flight research aircraft to conceive and mature new aeronautical concepts and provide databases and design methodology for critical technical disciplines in aircraft design. Prior to World War II (WWII), research at Langley on such diverse topics as airfoils, aircraft structures, engine cowlings and cooling, gust alleviation, and flying qualities was widely disseminated within the civil aviation community, and well-known applications of the technology to civil aircraft were commonplace. During WWII, however, the facilities and personnel of Langley were necessarily focused on support of the Nation's military efforts. Following WWII, aeronautical research at Langley was stimulated by the challenges of high speed flight and the associated problems that were exhibited by high-speed aircraft configurations operating at relatively low speeds, such as those used for takeoff and landing. Much of Langley's research during that time would ultimately be useful to both the civil and military aviation industries. With the emergence of the new National Aeronautics and Space Administration (NASA) in 1958, Langley retained its vital role in aeronautical research and assumed a leading position as NASA Langley Research Center, along with Ames Research Center, Lewis Research Center (now Glenn Research Center), and Dryden Flight Research Center. Langley's legacy of critical contributions to the civil aviation industry includes a wide variety of activities ranging from fundamental physics to applied engineering disciplines. Through the mechanisms of NASA technical reports, technical symposia, meetings with industry, and cooperative projects, the staff of Langley Research Center has maintained an awareness of the unique problems and challenges facing the U.S. civil aviation industry. With a sensitivity toward these unique requirements, Langley researchers have conceived and conducted extremely relevant research that has been applied directly to civil aircraft. These applications have resulted in increased mission performance, enhanced safety, and improved competitiveness. This document is intended to be a companion to NASA SP-2000-4519, "Partners in Freedom: Contributions of the Langley Research Center to U.S. Military Aircraft of the 1990s." Material included in the combined set of volumes provides informative and significant examples of the impact of Langley's research on U.S. civil and military aircraft of the 1990s. As worldwide advances in aeronautics and aviation continue at a breathtaking pace, documenting the significant activities, individuals, and events that have shaped the destinies of U.S. civil and military aviation has become increasingly important. In the research and development communities, many instances have occurred where fundamental, groundbreaking efforts have been forgotten or confused because of turnover of staffs, loss of technical records, and lack of documentation. This volume, "Concept to Reality: Contributions of the NASA Langley Research Center to U.S. Civil Aircraft of the 1990s," highlights significant Langley contributions to safety, cruise performance, takeoff and landing capabilities, structural integrity, crashworthiness, flight deck technologies, pilot-vehicle interfaces, flight characteristics, stall and spin behavior, computational design methods, and other challenging technical areas for civil aviation.
