The Wingrove Parameter: A new Turbulence Metric

摘要

This paper discusses the development of a real-time turbulence metric called the Wingrove parameter. This metric is proportional to the turbulent kinetic energy of the vertical wind. It is computed from Digital Flight Data Recorder (DFDR) information after the elimination of gust scales that do not contribute to aicraft turbulence via a numerical filter. Preliminary results from this study show a strong correlation between high aircraft vertical accelerations and large Wingrove parameters except in a maneuvering case. It is conclded that the Wingrove parameter is a strong candidate for a standardized, quantitative, real-time turbulence metric.
