Aircraft wake vortices can pose a threat, especially in the terminal environment where aircraft operate in close proximity. Vortex separation standards preclude hazardous encounters, but are oftentimes very conservative. A key to increasing airport capacity is to know when vortices are not a hazard so that aircraft can land and take off with closer intervals. A conference was held in London to address the capacity and wake vortices issue. This paper provides a brief overview of the highlights of the oral presentations.
Wake turbulence considerations currently restrict the use of parallel runways less than 2500 ft (762 m) apart.However, wake turbulence is not a factor...
The paper describes how to use simple models and, if needed, sensitivity analyses to determine the wake vortex categories for new aircraft. The method...
