A Concept for Using Multiple Glide Slope Angles for Wake Vortex Avoidance on Parallel IFR (Instrument Flight Rule) Approaches,

Abstract

For parallel runways separated by less than 2500 feet, the longitudinal separation between aircraft on adjacent approaches must be maintained at the same distance as if the aircraft were on a single runway. The hazard associated with trailing wing tip vortices is the major hindrance to reducing separation distances during instrument approaches. This report shows how separations can be safely reduced on closely spaced parallel runways. The analysis exploits the use of staggered runway thresholds, multiple glide slope angles, and wind measurement devices to ensure vortex avoidance. The analysis is applied to Denver Stapleton International Airport. Keywords: Parallel Runways; Wake Vortex.
