291.44 BTS Schedule P12(a), Fuel Consumption by Type of Service and

Entity.

top

(a) For the purposes of BTS schedule P12(a), type of service shall be

either scheduled service or nonscheduled service as those terms are

defined in 291.45(c)(2) and (3).

(b) For the purpose of this schedule, scheduled service shall be reported

separately for:

(1) Intra-Alaskan operations;

(2) Domestic operations, which shall include all operations within and

between the 50 States of the United States (except Intra-Alaska), the

District of Columbia, the Commonwealth of Puerto Rico and the United

States Virgin Islands, or a U.S. territory or possession to a place in any

State of the United States the District of Columbia, the Commonwealth of

Puerto Rico and the United States Virgin Islands, or a U.S. territory or

possession;

(3) International operations are flight stages with one or both terminals

outside the 50 States of the United States, the District of Columbia, the

Commonwealth of Puerto Rico and the United States Virgin Islands, or a

U.S. territory or possession.

(c) For the purpose of this schedule, nonscheduled service shall be

reported separately for domestic operations and international operations

as defined in paragraphs (b)(2) and (b)(3) of this section, except that

domestic and international Military Airlift Command (MAC) operations shall

be reported on separate lines.

(d) The cost data reported on each line shall represent the average cost

of fuel, as determined at the station level, consumed in that geographic

entity.

(e)(1) The cost of fuel shall include shrinkage, but excludes:

(i) Throughput and in to plane fees, i.e., service charges or

gallonage levies assessed by or against the fuel vendor or concessionaire

and passed on to the carrier in a separately identifiable form; and

(ii) Nonrefundable Federal and State excise taxes.

(2) However, through-put and in to plane charges that cannot be

identified or segregated from the cost of fuel shall remain a part of the

cost of fuel as reported on this schedule.

(f) Each air carrier shall maintain records for each station showing the

computation of fuel inventories and consumption for each fuel type. The

periodic average cost method shall be used in computing fuel inventories

and consumption. Under this method, an average unit cost for each fuel

type shall be computed by dividing the total cost of fuel available

(Beginning Inventory plus Purchases) by the total gallons available. The

resulting unit cost shall then be used to determine the ending inventory

and the total consumption costs to be reported on this schedule.

(g) Where amounts reported for a specific entity include other than Jet A

fuel, a footnote shall be added indicating the number of gallons and

applicable costs of such other fuel included in amounts reported for that

entity.

(h) Where any adjustment(s) recorded on the books of the carrier results

in a material distortion of the current month's schedule, carriers shall

file a revised Schedule P12(a) for the month(s) affected.

U.S. Air Carrier Traffic and Capacity Data by Nonstop Segment and

On-Flight Market.

(b) Schedule T100 shall be filed monthly.

(1) Schedule T100 collects summarized flight stage data and on-flight

market data for revenue flights. All traffic statistics shall be compiled

in terms of each flight stage as actually performed. The detail T100 data

shall be maintained in such a manner as to permit monthly summarization

and organization into two basic groupings. First, the nonstop segment

information which is to be summarized by equipment type, within class of

service, within pair-of-points, without regard to individual flight

number. The second grouping requires that the enplanement/deplanement

information be broken out into separate units called on-flight market

records, which shall be summarized by class of service, within

pair-of-points, without regard for equipment type or flight number.

(2) Joint-service operations. The Department may authorize joint-service

operations between two direct air carriers. Examples of these

joint-service operations are: blocked-space agreements; part-charter

agreements; code-sharing agreements; wet-lease agreements, and similar

arrangements.

(i) Joint-service operations are reported by the carrier in operational

control of the flight, i.e., the carrier that uses its flight crews under

its own FAA operating authority. The traffic moving under these agreements

is reported on Schedule T100 the same way as any other traffic on the

aircraft.

(ii) If there are questions about reporting a joint-service operation,

contact the BTS Assistant DirectorAirline Information (fax no. 202

3663383, telephone no. 202 3664373). Joint-service operations are

reported in Schedule T100 in accordance with this paragraph (b).

(iii) Operational control. The air carrier in operational control of the

aircraft (the carrier that uses its flight crews under its own FAA

operating authority) must report joint services.

(c) Service classes. (1) The statistical classifications are designed to

reflect the operating characteristics attributable to each distinctive

type of service offered. The combination of scheduled and nonscheduled

operations with passenger, all-cargo, and military services are placed

into service classes as follows:

CodeType of service

FScheduled Passenger/Cargo.

GScheduled All-Cargo.

LNonscheduled Civilian Passenger/Cargo/

PNonscheduled Civilian Cargo.

NNonscheduled Military Passenger/Cargo.

RNonscheduled Military Cargo.

(2) Scheduled services include traffic and capacity elements applicable to

air transportation provided pursuant to published schedules and extra

sections of scheduled flights. Scheduled Passenger/Cargo (Service Class F)

is a composite of first-class, coach, and mixed passenger/cargo service.

(3) Nonscheduled services include all traffic and capacity elements

applicable to the performance of nonscheduled aircraft charters, and other

air transportation services not constituting an integral part of services

performed pursuant to published flight schedules.

(d) Air transport traffic and capacity elements. Within each of the

service classifications, carriers shall report air transport traffic and

capacity elements. The elements are reported on segment and/or market

Appendix to 291.45Instructions to U.S. Air Carriers for Reporting

Traffic and Capacity Data on Schedule T100

(a) Format of reports (1) Automatic Data Processing (ADP) magnetic tape.

Refer to paragraph (d) of this appendix for instructions pertaining to

mainframe and minicomputer reporting. The Department will issue

Accounting and Reporting Directives to make necessary technical changes

to these T100 instructions. Technical changes which are minor in nature

do not require public notice and comment.

(2) Microcomputer diskette (i) Optional specification. If an air carrier

desires to use its personal computers (PC's), rather than mainframe or

minicomputers to prepare its data submissions, the following

specifications for filing data on diskette media apply.

(ii) Reporting medium. Microcomputer ADP data submission of T100

information must be on IBM compatible disks. Carriers wishing to use a

different ADP procedure must obtain written approval to do so from the BTS

Assistant DirectorAirline Information. Requests for approval to use

alternate methods must disclose and describe the proposed data

transmission methodology. Refer to paragraph (i) of this appendix for

microcomputer record layouts.

(iii) Microcomputer file characteristics. The files will be created in

ASCII delimited format, sometimes called Data Interchange Format (DIF).

This form of recording data provides for variable length fields (data

elements) which, in the case of alphabetic data, are enclosed by quotation

marks () and separated by a comma (,) or tab. Numeric data elements that

are recorded without editing symbols are also separated by a comma (,) or

tab. The data are identified by their juxtaposition within a given record.

Therefore, each record must contain the exact number of data elements, all

of which must be juxtapositionally correct. Personal computer software

including most spreadsheets, data base management programs, and BASIC are

capable of producing files in this format.

(b) Filing date for reports. The reports must be received at BTS within 30

days following the end of each reporting period.

(c) Address for filing. Data Administration Division, K14, Office of

Airline Information, Bureau of Transportation Statistics, U.S. Department

of Transportation, 1200 New Jersey Avenue, SE., Washington, DC 205900001.

(d) ADP format for magnetic tape (1) Magnetic tape specifications. IBM

compatible 9-track EBCDIC recording. Recording density of 6250 or 1600

bpi. The order of recorded information is:

(i) Volume label.

(ii) Header label.

(iii) Data records.

(iv) Trailer label.

(2) [Reserved]

(e) External tape label information. (1) Carrier name.

(2) Report date.

(3) File identification.

(4) Carrier address for return of tape reel.

(f) Standards. It is the policy of the Department to be consistent with

the American National Standards Institute and the Federal Standards

Activity in all data processing and telecommunications matters. It is our

intention that all specifications in this application are in compliance

with standards promulgated by these organizations.

(g) Volume, header, and trailer label formats (1) Use standard IBM label

formats. The file identifier field of the header labels should be

T100.SYSTEM.

(h) Magnetic tape record layouts for T100 (1) Nonstop segment record

layout.

(i) Record layouts for microcomputer diskettes. The record layouts for

diskette are generally identical to those shown for magnetic tape, with

the exception that delimiters (quotation marks, tabs and commas) are used

to separate fields. It is necessary that the order of fields be maintained

in all records.

(1) File characteristics. The files will be created in ASCII delimited

format, sometimes called Data Interchange Format (DIF). This form of

recording data provides for variable length fields (data elements) which,

in the case of alphabetic data, are enclosed by quotation marks () and

separated by a comma (,) or tab. Numeric data elements that are recorded

without editing symbols are also separated by a comma (,) or tab. The data

are identified by their juxtaposition within a given record. Therefore, it

is critical that each record contain the exact number of data elements,

all of which must be juxtapositionally correct. PC software including most

spreadsheets, data base management programs, and BASIC produce minidisk

files in this format.

(2) File naming conventions for diskettes. For microcomputer reports, each

record type should be contained in a separate DOS file on the same

physical diskette. The following DOS naming conventions should be

followed:

(i) Record type S = SEGMENT.DAT

(ii) Record type M = MARKET.DAT

(b) Detailed international on-flight market and nonstop segment data in

Schedule T100 and Schedule T100(f) reports, except military data, shall

be publicly available immediately following the Department's determination

that the database is complete, but no earlier than six months after the

date of the data. Military operations are reported under service codes N

or R. Data for on-flight markets and nonstop segments involving no U.S.

points shall not be made publicly available for three years. Industry and

carrier summary data may be made public before the end of six months or

the end of three years, as applicable, provided there are three or more

carriers in the summary data disclosed. The Department may, at any time,

publish international summary statistics without carrier detail. Further,

the Department may release nonstop segment and on-flight market detail

data by carrier before the end of the confidentiality period as follows:

(1) To foreign governments as provided in reciprocal arrangements between
