Bringing together for the first time in the English language a wealth of Eastern and Western research and practical developments, Wake Vortex Control addresses the challenging issue of wake turbulence and its management. Covering relevant theoretical background, past work and modeling techniques alongside regulatory frameworks and operational issues, the book takes an interdisciplinary approach and highlights essential research that has moved the field forward. Critically, it considers in detail the design implications of wake vortex, promoting an approach that sees low wake vortex wing development taken into account in the early stages of aircraft design. Featuring examples of current control techniques and practical design advice, Wake Vortex Control will help researchers, engineers and designers to move closer towards aircraft optimization for maximum performance and minimum wake hazard. Brings together frontline research on wake vortex effects from leading groups across the world. Focuses on methods for control and management in addition to the theory and modeling information covered by other titles. Features practical advice and examples of wake vortex minimization efforts undertaken in the early stage of large aircraft design.

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.

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.

DOT/FAA/RD-95/6 DOT-VNTSC-FAA-95-4 Federal Aviation Administration, Final Report, April 1995 Airframe manufacturers, aircraft associations, airlines, pilot groups, air traffic controllers, government and regulatory agencies, and other organizations and individuals have developed this training resource dedicated to reducing the number of wake-turbulence accidents and incidents. The training package consists primarily of this document. Additionally, a companion video developed by the Wake Turbulence Training Aid Industry Team is also available. Wake-turbulence accidents and incidents have been, and continue to be, a significant contributor to the worldwide safety statistics. The National Transportation Safety Board (NTSB), in a report on safety issues related to wake-vortex encounters, stated that data shows that between 1983 and 1993, there were at least 51 accidents and incidents in the United States that resulted from probable encounters with wake vortices. As a result of these encounters, 27 occupants were killed, eight were seriously injured, and 40 aircraft were substantially damaged or destroyed. In this report, the NTSB raised concern over "the adequacy of air traffic control procedures" and "pilot knowledge related to the avoidance of wake vortices."
