Abstract:The focus on optimizing aircraft fuel efficiency
as well as interest in assessing aviation
emissions inventories to measure the efficacy of
efforts to limit or reduce aviation emissions
worldwide has spurred a number of efforts in
the U.S. and Europe to develop robust computer
models capable of assessing aircraft emissions
at local, regional, and global levels. The
present contribution shows both a macro and
micro level example of the types of analyses that
the Federal Aviation Administration?s (FAA)
System for assessing Aviation?s Global
Emissions (SAGE) enables. On the macro level,
examples are given of global inventory
information computed using SAGE. In addition,
a micro-level assessment of fuel burn, emissions
and related costs associated with the 2995 nmi
(Great Circle), New York (JFK)-to-London
(EGLL) origin-destination (O-D) pair is
provided.
We highlight this O-D pair since: (1) it is an
extremely popular trans-oceanic pair, with a
large number of operations; (2) radar-based
aircraft position data from FAA?s Enhanced
Traffic Management System are available for
all flights hence enhancing the confidence of the
analyses; and (3) a variety of aircraft (B747,
B767 and B777), operated by several different
international carriers are represented on this
O-D pair, which highlights the versatility and
robustness of the model. SAGE supports
decision making to manage and mitigate
aviation fuel consumption and emissions,
thereby enabling the sustained growth of this
critical mode of transportation.
