Scope:

This AIR describes procedures for calculating emissions resulting from the main engines of commercial jet and turboprop aircraft through all modes of operation for all segments of a flight. Piston engine aircraft emissions are not included in this AIR. Some information about piston engine aircraft emissions can be found in FOCA 2007. The principal purpose of the procedures is to assist model developers in calculating aircraft emissions in a consistent and accurate manner that can be used to address various environmental assessments including those related to policy decisions and regulatory requirements.

Rationale:

This Aerospace Information Report (AIR) describes procedures for calculating emissions resulting from operations of jet and turboprop aircraft through all modes of operation. The procedures assume that reference emissions and performance data are available for each airplane involved. The fundamental element of the procedures is a method for deriving emissions indices for an airplane when performing any specified operation for a segment of a flight. The principal purpose of using the procedures is to assist model developers in calculating aircraft emissions in a consistent and accurate manner that can be used to address various environmental assessments including those related to policy decisions and regulatory requirements. Rather than presenting one method, many viable methods are presented for both emissions and aircraft performance modeling with descriptions of the uncertainties involved. As a loose guide to the user, the methods are also ordered such that the most accurate methods are presented first in each section based on current understanding. This document is intended to be updated periodically. Hence, the methodology descriptions and uncertainty assessments will be modified accordingly as the various methods evolve and new information becomes available.
