Air TripAny trip in which the type of transportation used to cover most of the miles on that trip was either by commercial airplane or a personal or corporate airplane. ( American Travel Survey (ATS) 1995 )
Aircraft And Traffic Servicing ExpensesCompensation of ground personnel, in-flight expenses for handling and protecting all non-passenger traffic including passenger baggage, and other expenses incurred on the ground to (1) protect and control the in-flight movement of the aircraft, (2) schedule and prepare aircraft operational crew for flight assignment, (3) handle and service aircraft while in line operation, and (4) service and handle traffic on the ground after issuance of documents establishing the air carrier's responsibility to provide air transportation. ( Air Carrier Financial Reports (Form 41 Financial Data) )
Aircraft ConfigurationThe type of payload an aircraft was designed to carry: passenger, cargo, or both. ( Air Carrier Statistics (Form 41 Traffic)- All Carriers, Air Carrier Statistics (Form 41 Traffic)- U.S. Carriers )
Aircraft Days AssignedThe number of days that aircraft owned or acquired through rental or lease (but not inter-change) are in the possession of the reporting air carrier and are available for service on the reporting carrier's routes plus the number of days such aircraft are in service on routes of others under interchange agreements. Includes days in overhaul, or temporarily out of service due to schedulecancellations. Excludes days that newly acquired aircraft are on hand but not available or formally withdrawn from air transport service. ( Air Carrier Summary Data (Form 41 and 298C Summary Data) )
Aircraft HoursThe airborne hours of aircraft computed from the moment an aircraft leaves the ground until it touches the ground at the end of a flight stage. ( Small Air Carrier Statistics (Form 298C Traffic Data) )
Aircraft Operating ExpensesExpenses incurred directly in the in-flight operation of aircraft. ( Air Carrier Financial Reports (Form 41 Financial Data) )
Airline IDAn identification number assigned by US DOT to identify a unique airline (carrier). A unique airline (carrier) is defined as one holding and reporting under the same DOT certificate regardless of its Code, Name, or holding company/corporation. Use this field for analysis across a range of years. ( Air Carrier Summary Data (Form 41 and 298C Summary Data), Air Carrier Statistics (Form 41 Traffic)- All Carriers, Aviation Support Tables, Air Carrier Financial Reports (Form 41 Financial Data), Airline On-Time Performance Data, Air Carrier Statistics (Form 41 Traffic)- U.S. Carriers )
Airport CodeA three character alpha-numeric code issued by the U.S. Department of Transportation which is the official designation of the airport. The airport code is not always unique to a specific airport because airport codes can change or can be reused. ( Air Carrier Statistics (Form 41 Traffic)- All Carriers, Air Carrier Statistics (Form 41 Traffic)- U.S. Carriers, Airline On-Time Performance Data, Air Carrier Summary Data (Form 41 and 298C Summary Data), Airline Origin and Destination Survey (DB1B), Small Air Carrier Statistics (Form 298C Traffic Data), Aviation Support Tables )
Airport IDAn identification number assigned by US DOT to identify a unique airport. Use this field for airport analysis across a range of years because an airport can change its airport code and airport codes can be reused. ( Air Carrier Summary Data (Form 41 and 298C Summary Data), Air Carrier Statistics (Form 41 Traffic)- All Carriers, Air Carrier Statistics (Form 41 Traffic)- U.S. Carriers, Aviation Support Tables, Airline Origin and Destination Survey (DB1B), Airline On-Time Performance Data )
Arrival DelayArrival delay equals the difference of the actual arrival time minus the scheduled arrival time. A flight is considered on-time when it arrives less than 15 minutes after its published arrival time. ( Airline On-Time Performance Data )
AssetsCurrent Assets include cash, accounts receivable, notes receivable. Long-term assets include net carrier operating property. ( Motor Carrier Financial & Operating Information )
Available Seat MilesThe aircraft miles flown in each inter-airport segment multiplied by the number of seats available for revenue passenger use on that segment. ( Small Air Carrier Statistics (Form 298C Traffic Data) )
Average Miles Per ShipmentThe 1993 CFS excluded shipments of STCC 27, Printed Matter, from calculation of average miles per shipment. This was done after determining that respondents in the 1993 CFS shipping newspapers, magazines, catalogs, etc., had used widely varying definitions of the term shipment. In the 1997 CFS, numerous efforts were made during data collection and editing to produce consistent results from establishments shipping SCTG 29, Printed Products. As a result, average miles per shipment for printed products is included in calculations for the 1997 CFS. ( Commodity Flow Survey (CFS) )
