A global air traffic emissions database is an essential tool for both policy makers and climate change scientists. The last comprehensive aircraft emissions inventories date from 1992, therefore an update was necessary. This need is being addressed in Europe through a project entitled AERO2K. The Eurocontrol Experimental Centre’s SEE (Society, Environment and Economy) Business Area became involved in this European project. The objectives of the work package led by Eurocontrol were to produce a worldwide civil air traffic movement inventory in order to assess aviation related emissions geographically. The database consists of 4-D flight trajectories (latitude, longitude, altitude and time) enabling project partners to calculate fuel consumption and emissions. This database should supply data, which are not currently available. The collection of data for the year 2002 was spread over six representative periods of one week each for North America and Europe. Considering six weeks of data allowed taking into account diurnal, weekly and seasonal variation in air traffic. Data for the rest of the world were extracted from Back Aviation a commercial database. The collection of data required the collaboration of aviation authorities in order to gather as many measured flight trajectory data as possible. Schedule data from Back Aviation database does not include any flight trajectory information. It was thus necessary to complete this data with flight route and aircraft performance information when available. The various formats, origin and sheer-size of data involved necessitated the development of a toolset allowing the automatic importation of the data, their filtering, their standardization, their analysis, their merging and the storage of the final flight movement inventory. Analytical studies for improving data quality and creating trajectories for schedule data were carried out. For the days of the year for which no data were collected, flight data were derived from inventories realized for the data collection periods while trends were obtained from Back Aviation scheduled flights database. A prototype database application was initially developed in MS Access with pilot data from Europe and North America. The final application was migrated to an Oracle 9i database toolset and the data collection was extended worldwide. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址:AERO2K Flight Movement Inventory Project Report(7)
