Airport Alpha Code: The three letter code identifying the airport. This code is used .in all of the major airline reservation systems and is recognized by the International Air Transport Association (IATA). B. Airport Numeric Code: A five digit code which corresponds to the alphabetic name spelling of the principal city served by the airport. Airports that share service at a particular city will therefore have identical numeric codes. The number is used primarily for sorting records by city name and for grouping multiple airports within a city. C. World Area Code: A three digit code which specifies in what area of the world a city is located. The first digit represents a major geographic area, such a "O" for the United States, "4" for Europe, etc. The last two digits represent a specific subdivision of the major geographic area, such as a state or a country. Contact the Office of Airline Information at the address listed on the cover for a complete list of these area codes. D. City Name: The name of the principal city served by this airport. Page 5 of 8 NARA Reference Copy .·. E. Carrier Alpha Code: The 2 or 3 character code used to represent the carrier reporting these data to the DOT. F. Carrier Entity Code: A five-character code assigned to each air carrier that is used primarily for DOT reporting purposes. It is used to separate the Domestic, Atlantic, Latin America, and Pacific operations of each air carrier. Contact the Office of Airline Information at the address listed on the cover for a complete list of carrier entity codes. G. Carrier Group Code: This numeric code classifies the US air carriers by the amount of total operating revenue for the previous year unless the carrier is a domestic ONLY all-cargo. Domestic ONLY All-Cargo carriers are assigned the Carrier Group Code 8. When the DB28's are generated, the Carrier Group Codes are ... International Carriers - 0 _Regional Carriers - 1 (Includes Large, Medium, Commuter, Small Certificated) National Carriers - 2 Major Carriers - 3 Domestic Only All Cargo Carriers - 8 H. Distance: Page 6 of 8 NARA Reference Copy . The great circle distance in statute miles between the Origin and Destination airports. I. Service Class: The Service Class Code refers to the class of service used. F Scheduled Passenger/Cargo Service G Scheduled All Cargo Service L Non-Scheduled Civilian Passenger Service P Non-Scheduled Civilian All Cargo Service J. Aircraft Type: Type of aircraft used on the non-stop segment. 1. Aircraft Group Code. This code indicates the general category of aircraft type reported. 2. Aircraft Type Code. This code indicates the specific make and model of the aircraft. 3. Cabin Configuration Code. Passenger = "1", Cargo = "2", Combination Passenger/Cargo = "3". K. Departures: Revenue Aircraft Departures: 1. The number of revenue aircraft departures performed in revenue scheduled service, including extra sections. 2. The number of aircraft departures scheduled, whether or not actually performed. Page 7 of 8 NARA Reference Copy L. Available Capacity: 1. Available Capacity-Payload reflects the total available capacity for passenger, freight, and mail applicable to the aircraft with which this flight is performed. 2. Available Seats reflect the actual number of seats for sale, excluding those blocked for safety or operational reasons. M. Cabin Identification: Cabin (First, Coach, and Middle) passenger data are not identified for US air carriers operating in domestic markets. All data are consolidated into First Cabin, and the Middle and Coach Cabin Fields will each contain a value of zero. N. Elapsed Time: The total elapsed time computed in minutes. 1. Ramp-to-Ramp time is the total elapsed time computed from the moment the aircraft moves under its own power until it comes to rest at the next point of landing. 2. Airborne time is the elapsed time computed from the moment the aircraft leaves the ground until it touches down at the next point of landing. Page 8 of 8 NARA Reference Copy ii ,. DEPARTMENT OF TRANSPORTATION BUREAU OF TRANSPORTATION STATISTICS OFFICE OF AIRLINE INFORMATION ACCOUNTING AND REPORTING DIRECTIVE No. 260 Issue Date: 6/28/2002 Effective Date: July 1, 2002 Parts:217, 241, 298 LIST OF NUMERIC AIRCRAFT TYPE CODES This directive applies to U.S. and foreign air carriers, and it replaces Accounting and Reporting Directive No. 252, dated February 15, 2001~ We have added aircraft type codes for the Boeing 737-600 and 737-900 series aircraft, the Embraer 140 and the Piper PA-12 Super Cruiser. Also, we wish to remind air carriers that the Dornier 328 have jet and turbo-prop versions of the aircraft. There are different aircraft type codes for the different versions of the Dornier aircraft. AIRCRAFT TYPE CODES Boeing 737-500 new code is 616 Boeing 737-600 new code is 633 Boeing 737-800 new code is 614 Boeing 737-900 new code is 634 Embraer 140 new code is 676 Piper PA-12 Super cruiser new code is 086 DORNIER 328 Dornier 328 turbo-prop aircraft type code 449 Dornier 328 twin-jet aircraft type code 632 CABIN CONFIGURATION DIGIT The aircraft code is comprised of four numeric positions. The first three positions identify the aircraft type. The fourth position identifies the cabin configuration or that the aircraft is equipped for water landings. For instance, the numeric code for reporting a standard passenger/cargo B-747-100 is 8161; 816 is the code for the Boeing 747-lOD aircraft and the 4th digit {a cabin configuration digit) 11 1 11 identifies the passenger/cargo configuration. The cabin configuration digit can be either 1, 2, 3 or 4 as follows: · 11 1 11 = a normal passenger/cargo configuration. Passengers on the main deck and cargo below; NARA Reference Copy 11 2 11 = an all cargo freighter; ) 11 3 11 = a main deck configuration with separate compartments for both cargo and passengers; and 11 4 11 = aircraft equipped for water landings. Specific requests to add aircraft-type numeric codes, or to clarify or amend an assigned code should be addressed to Ms. Phyllis Guthrie, in care of this office or by e-mail to [email protected].
