Data Bank 21 - Form 41 Schedule T-2 (T-100) Quarterly Traffic and Capacity Data of US Air Carriers, Summarized by Aircraft Type: second quarter: [2012]

This CD is derived from monthly T-100 Segment/Market reports. This data bank presents traffic data (i.e., revenue passenger-miles and revenue ton-miles for all classes of passengers and cargo), capacity (i.e., available seat-miles and available ton-miles), and certain aircraft statistics (i.e., aircraft hours and fuels and oils issued) for one aircraft type flown by the reporting carrier. All data items are summarized by carrier entity, date, and aircraft type. Data are available since 1991. NOTE: Prior to October 2002, this product was derived by summarizing data submitted by U.S. air carriers in monthly T-100 Segment/Market reports and quarterly supplemental Schedule T-2 reports of domestic all-cargo and domestic charter data. Effective October 2002, carriers are required to report all-cargo and charter data on monthly Segment/Market reports.

本数据集源自月度T-100航段/市场报告（T-100 Segment/Market reports）。本数据库涵盖报告航司运营的单一机型的三类统计信息：一是运输量数据，即各舱位旅客与货运的收入客英里、收入吨英里；二是运力数据，即可用座位英里、可用吨英里；三是部分航空器统计数据，即航空器飞行时长、燃油与滑油发放量。所有数据条目均按航司主体、统计日期及机型进行汇总。该数据集的历史数据可追溯至1991年。
注：2002年10月之前，本数据集通过汇总美国航司提交的月度T-100航段/市场报告，以及国内全货运与国内包机数据的季度补充T-2计划表报告（Schedule T-2 reports）生成。自2002年10月起，航司需在月度航段/市场报告中报送全货运与包机相关数据。
