For additiona information and guidance on conducting aircraft emissions inventory, see
the following publication:

D2.2 Data Sources (p. D-6)
D2.2.1 Aircraft type and Number of LTOs
Aircraft type and number of LTOs can be obtained from a variety of sources including
(but not limited to) airport master plans, airport tower records and noise
assessments. Another source of data is the Bureau of Transportation Statistics (BTS)’s
Office of Airline Information (OAI), which is part of the U.S. DOT. The OAI
Airport Activity Statistics of Certificated Route Air Carriers provides detailed tab es listing
annual airline and aircraft activity by airport (as shown in the Attachment 4 example
page). For additional information, contact the BTS directly at 1-800-853-1351

For air quality analyses, the actual (or forecasted actual) aircraft fleet mix should be used
(e.g., rather than an adjusted fleet that includes aircraft substitutions based on available
Wherever aircraft substitutions are necessary for emissions analysis
purposes, these can be made using similar aircraft operationa and/or performance
characteristics (including size and manufacturer) as a basis.

ICAO Engine Exhaust Emissions Databank referenced in the text is now available in

Between EDMS 3.2 and EDMS 4.0
A variety of aircraft time in mode data (including taxi-in, taxi-out and ground-based delay)
can be obtained from a variety of sources including (but not limited to) airport master
plans, in-the-field measurements, ICAO, and airport operational models (i.e. SIMMOD).
Takeoff, climb out, approach and the landing roll portion of the idle mode TIMs are
aircraft-specific in EDMS. They are generated using flight profile data that are based on
the airframe, engine, takeoff weight, and approach angle to
information can be found in the EDMS User’s Manual on TIMs.
The BTS OAI website has an airline on-time statistics searchable database. From this
database, one can obtain summary statistics including airport average taxi-in and taxi-out
times, or detailed statistics including taxi-in and taxi-out times by airport and airline.
