Wind Information Requirements for NextGen Applications Phase 1: 4D-Trajectory Based Operations (4D-TBO).

摘要

Many future air transportation system concepts require access to high quality wind information if they are to be effective. The primary objective of this work is to quantify the relationship between wind information quality and benefits delivery under future applications envisioned under the Next Generation Air Transportation System (NextGen). Relevant wind information quality factors have been identified in this work in terms of timeliness, spatial resolution, temporal resolution and intrinsic forecast accuracy. Quantitative metrics that capture the impacts of these different factors have also been explored, particularly in terms of Root Mean Square Vector Error (RMSVE) that effectively captures aggregate performance, and other metrics that more effectively capture large point errors. An extensive review has been conducted against these factors and metrics of wind forecast capabilities available in the U.S. and UK operational aviation system, as well as research models which may become available to the community in the near future. This has allowed realistic ranges of appropriate wind information quality metrics to be defined for use in the context of this study.
