Data Source  Description  Traffic Flow Management  System Counts (TFMSC)  database  Records aircraft operations at a facility that are either detected under Instrumental  Flight Rules (IFR) by Air Traffic Control (ATC), or for which pilots have filed a  flight plan, only a subset of the military and GA operational activity is available  via TFMSC. After acquiring a login from FAA, this information can be accessed  at the following website: https://aspm.faa.gov/tfms/sys/.  Source: FAA; BUCHair USA Inc., 2013; Airport IQ5010, 2013; Bureau of Transportation Statistics (BTS), 2013; and ACRP  Report 84,  Guidebook for Preparing Airport Emissions Inventories for State Implementation Plans , 2013.  In those cases where the data sources  listed in  Table A1-2  ( Aircraft Operational Input Data  Sources ) are unavailable, a recent airport study, an airport’s Form 5010 Airport Master Record  (ARM), or an Airport System Plan (ASP) prepared by a state/local transportation agency may  contain these data. Other recommended data sources include a current Airport Master Plan  (AMP), a Federal Aviation Regulations (FAR) Part 150 Noise Study, or an Environmental  Impact Statement/Assessment (EIS/EA) for the airport, if available and up-to-date.  Future year airport operational data may also be obtained from a recent airport study and/or the  Terminal Area Forecast (TAF) for National Plan of Integrated Airport Systems (NPIAS) airports  (with and without an  Air Traffic Control  Tower [ATCT]) and from an ASP or the Aerospace Forecast for all other airports  as well as from the reference sources listed in  Table  A1-2  ( Aircraft Operational Input Data Sources ).  Aircraft type and engine data may be obtained from a number of aviation industry publications  listed in  Table A1-3  ( Fleet Mix Input Data Sources ).  6$_{ }$ A1.3.2  Fleet Mix  Data Source  Description  JP Airline Fleets  Provides comprehensive aircraft information (including current registration, serial number, previous identity, date of manufacture, date of delivery, engine type and  number, maximum take -off weight, configuration, fleet number, name, etc.). information is proprietary and can be purchased at the http://www.buchair.com/JPAF.htm.  OAG Absolute Aviation  Advantage  Provides flight schedules, flight status and aviation data for over 900 airlines and over  4,000 airports. Proprietary source ; can be ordered at the following http://www.oag.com/Global.  Airport Noise &  Operations Monitoring  System (ANOMS)  Provides tail number, aircraft type, r unway usage, airline, operation type (i.e., arrival  and departure), and the destination/origin for aircraft operations . The ANOMS does not capture every aircraft operation at an airport. Airports are not required to have an  ANOMS so systems are in limited use.  Air Carrier Statistics  Database  (T-100 database)  Earliest data year is 1990. Periods of data available for a month, a quarter, and a year.  Form 41/T-100 records are available for all of the airports in FAA’s NPIAS and 313  additional air transportation facilities. This database is  better suited for deriving fleet  mix than operational data. This database can be accessed at the following http://www.transtats.bts.gov/tables.asp?db_id=111&DB_Name=.  Table A1-3.
