Book excerpt: This viewgraph presentation reviews the cooperative work that FAA and NASA are engaged in to safely increase the capacity of the National Airspace System by studying the wake vortex operations. Wake vortex avoidance is a limiting factor in defining separation standards in the airport terminal area and could become a reducing separation standards in en route airspace.

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.

This book was released on 2018-06-12 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA Langley Research Center has a long history of aircraft wake vortex research, with the most recent accomplishment of demonstrating the Aircraft VOrtex Spacing System (AVOSS) at Dallas/Forth Worth International Airport in July 2000. The AVOSS was a concept for an integration of technologies applied to providing dynamic wake-safe reduced spacing for single runway arrivals, as compared to current separation standards applied during instrument approaches. AVOSS included state-of-the-art weather sensors, wake sensors, and a wake behavior prediction algorithm. Using real-time data AVOSS averaged a 6% potential throughput increase over current standards. This report describes a Concept of Operations for applying the technologies demonstrated in the AVOSS to a variety of terminal operations to mitigate wake vortex capacity constraints. A discussion of the technological issues and open research questions that must be addressed to design a Wake Vortex Advisory System (WakeVAS) is included.Rutishauser, David and Lohr, Gary and Hamilton, David and Powers, Robert and McKissick, Burnell and Adams, Catherine and Norris, EdwardLangley Research CenterAIRCRAFT WAKES; VORTEX ADVISORY SYSTEM; VORTICES; NASA PROGRAMS; AIRCRAFT APPROACH SPACING; AIR TRAFFIC CONTROL; ARRIVALS

Download or read book Advances in Human Aspects of Transportation written by Neville Stanton and published by Springer Nature. This book was released on 2021-06-26 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the latest advances in the research and development, design, operation, and analysis of transportation systems, including road, rail, aviation, aerospace and maritime as well as their supporting systems and infrastructure. Focusing specifically on the contributions made by human factors and ergonomics, it analyses a wealth of topics, methods and technologies associated to accident analysis, automated and autonomous vehicles, assessment of comfort and distraction of drivers, and environmental concerns, giving emphasis to intelligent transport systems and driver-assistance systems, among other topics. Based on contributions to the AHFE 2021 Conference on Human Aspects of Transportation, held virtually on July 25-29, 2021, from USA, this book offers extensive information on the latest human factors and ergonomics thinking and practice in the area of transportation, and a thought-provoking guide to researchers, graduate students and professionals in this field.

This book was released on 2019-01-18 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document contains a general description for data sets of a wake vortex system in a turbulent environment. The turbulence and thermal stratification of the environment are representative of the conditions on November 12, 2001 near John F. Kennedy International Airport. The simulation assumes no ambient winds. The full three dimensional simulation of the wake vortex system from a Boeing 747 predicts vortex circulation levels at 80% of their initial value at the time of the proposed vortex encounter. The linked vortex oval orientation showed no twisting, and the oval elevations at the widest point were about 20 meters higher than where the vortex pair joined. Fred Proctor of NASA's Langley Research Center presented the results from this work at the NTSB public hearing that started 29 October 2002. This document contains a description of each data set including: variables, coordinate system, data format, and sample plots. Also included are instructions on how to read the data.
