Résumé
Bureau of Transportation Statistics (2015). Departures (Airline Performance): Departures - Cancelled | Country: USA | State: North Dakota, 1987-2014. Data-Planet™ Statistical Ready Reference by Conquest Systems, Inc. [Data-file]. Dataset-ID: 007-002-007. Dataset: A flight that was listed in a carrier's computer reservation system during the seven calendar days prior to scheduled departure but was not operated. Note, this number is identical to Arrivals - Cancelled at the national (all) and airline levels, but different on all other levels. Airline on-time data are reported each month to the United States Department of Transportation (DOT), Bureau of Transportation Statistics (BTS) by US air carriers that have at least 1 percent of total domestic scheduled-service passenger revenues, plus additional carriers that report voluntarily. The data cover nonstop scheduled-service flights between points within the US, as described in 14 CFR Part 234 of DOT regulations. This dataset contains on-time departure performance data. Gate departure time is the instance when the pilot releases the aircraft parking brake after passengers have loaded and aircraft doors have been closed. Data are reported for the nation, by state, and by airport and airline. Airline mergers result in various reporting changes over the period. Joint reporting begins after Federal Aviation Administration approval of a single operating certificate. (1) January 2006: US Airways (US) and America West (HP) start to report jointly as US Airways (US). (2) January 2010: Delta (DL) and Northwest (NW) start to report jointly as Delta (DL). (3) January 2012: United (UA) and Continental (CO) start to report jointly as United (UA). (4) January 2012: Atlantic Southeast (EV) and ExpressJet (XE) start to report jointly as ExpressJet (EV), presented here as ExpressJet Combined (E*). For data through December 31, 2011, use the code EV for Atlantic Southeast and the code XE for ExpressJet. Beginning with January 1, 2012 data, use the code E* for ExpressJet Combined. Category: Transportation and Traffic, Industry, Business, and Commerce Source: Bureau of Transportation Statistics The Bureau of Transportation Statistics (BTS) was established as a statistical agency in 1992. The Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 created BTS to administer data collection, analysis, and reporting and to ensure the most cost-effective use of transportation-monitoring resources. BTS brings a greater degree of coordination, comparability, and quality standards to transportation data, and facilitates in the closing of important data gaps. http://www.bts.gov/ Subject: Air Transportation, Airline Industry, Business Travel, LeisureTravel, Flight Departures, Airlines, Airline Operations, Passenger AirTransportation, Airports

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Apprise à partir de 10 348 étiquettes directes de Codex et de 10 348 étiquettes directes de Gemma. Le mode candidate est l'union des têtes enseignantes seuillées; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont ni des étiquettes humaines ni des étiquettes directes de modèles de pointe.
