"Environmental issues are likely to impose the fundamental limitation
on air transportation growth in the 21st century."
NASA has recognized that concern in its strategic planning and
included these enabling technology goals in its "Aeronautics & Space
Transportation Technology: Three Pillars for Success:"
"Reduce emissions of future aircraft by a factor of three within
10 years, and by a factor of five within 20 years."
"Reduce the perceived noise levels of future aircraft by a factor
of two from today's subsonic aircraft within 10 years, and by
a factor of four within 20 years."
The Environmental Compatibility Assessment (ECoA) Core Team has
been directed by the Executive Council of the NASA ARMD
& Space Transportation Technology to assess the ability of current
programs to achieve these goals and to determine what additional
effort may be required (i.e., a "gap" analysis).
In response, the ECOA Core Team has adopted a vision that:
In collaboration with carriers, manufacturers, academia and other
government agencies, NASA will develop robust technology options
which ensure that environmental issues do not constrain the growth
of air transportation.
The Team's efforts will begin with a number of outreach activities
which seek to address environmental concerns of NASA's various customers
and stakeholders. With their help, the assessment and resulting
recommendations are expected to be completed in July 1998.
