Improving the accuracy of airport emissions inventories using disparate datasets

摘要: Environmental regulations require airports to report air quality emissions inventories (i.e., tons emitted) for aircraft such as carbon oxides (COx) and nitrogen (NOx). Traditional methods emission inventory calculations yield over-estimated due an assumption of the use maximum takeoff thrust settings all departures. To reduce costs, airlines “reduced” (such derated or flex temperature settings) that can be up 25% lower than setting. Thrust data each flight operation are not readily available those responsible inventory. This article describes approach estimate actual using algorithms combine radar surveillance track data, weather standardized performance models. A case study flights from Chicago's O’Hare airport exhibited average 86% (within 4% average...
