The atmospheric environment surrounding the crash of American Airlines Flight 587 is investigated. Examined are evidence for any unusual atmospheric conditions and the potential for encounters with aircraft wake vortices. Computer simulations are carried out with two different vortex prediction models and a Large Eddy Simulation model. Wind models are proposed for studying aircraft and pilot response to the wake vortex encounter.Proctor, Fred H. and Hamilton, David W. and Rutishauser, David K. and Switzer, George F.Langley Research CenterMETEOROLOGY; AIRLINE OPERATIONS; ACCIDENT INVESTIGATION; VORTICES; AIRCRAFT WAKES; CIVIL AVIATION; LARGE EDDY SIMULATION; TURBULENCE; STABILITY; CRASHES; AIRCRAFT PILOTS; AIRCRAFT SAFETY; VELOCITY DISTRIBUTION; WIND PROFILES; WEATHER

This book discusses human factors research directed towards realizing and assessing sustainability in the built environment. It reports on advanced engineering methods for sustainable infrastructure design, as well as on assessments of the efficient methods and the social, environmental, and economic impact of various designs and projects. The book covers a range of topics, including the use of recycled materials in architecture, ergonomics in buildings and public design, sustainable design for smart cities, design for the aging population, industrial design, human scale in architecture, and many more. Based on the AHFE 2018 International Conference on Human Factors, Sustainable Urban Planning and Infrastructure, held on July 21–25, 2018, in Orlando, Florida, USA, it offers various perspectives on sustainability and ergonomics. As such, it is a valuable reference resource for designers, urban engineers, architects, infrastructure professionals, public infrastructure owners, policy makers, government engineers and planners, as well as operations managers and academics active in urban and infrastructure research.

Jet airliner operations in the United States began in 1958, bringing, it was thought, a new era of fast, high, safe, smooth, sophisticated travel. But almost immediately, the new aircraft were involved in incidents and accidents that showed jets created new problems even as they solved old ones. This book discusses five disasters or near-disasters of the early Jet Age, experiences which shook the industry, regulators and public out of early complacency and helped build a more realistic foundation for safer air transportation. Special attention is paid to the 1966 destruction of Braniff International Airways Flight 250 in Nebraska. Nearly two years of inquiry helped advance the understanding of jet operations in severe weather and saw the first use of cockpit voice recorder technology in an aviation accident investigation. In addition, a University of Chicago professor, Dr. Tetsuya "Ted" Fujita, conducted a more intensive investigation of the weather system which downed Flight 250. Dr. Fujita's already extensive knowledge of thunderstorms and tornadoes led to his creation of the Fujita Scale of Tornado Intensity, the F-scale that we hear about so frequently during storm season.

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.

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.

The lift-generated wake vortices trailing behind an aircraft present a danger to aircraft following the same or nearby path. The degree of hazard to the following aircraft depends on the nature of the wake encountered in its flight path and on the ability of the aircraft to counter its effects. This report describes the current state of understanding of the factors that influence the motion and dissipation of wake vortices. The relationships of these factors to parameters that are measurable through meteorological sensors and from a priori knowledge of the vortex generating aircraft characteristics are discussed as an aid to structuring development plans for the creation of wake vortex advisory products by the Integrated Terminal Weather System (ITWS) and by special wake vortex sensors.
