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.

(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

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
