Sources: Aircraft classifications—www.pyramid.ch, Commercial aircraft encyclopedia. Emission rates—Federal Aviation Administration, 2004, SAGE aircraft data. Notes: Use-weighted averages apply to each aircraft class. Yellow = wide-body jets (2,000-mile or greater typical range). Blue = narrow-body jets (500–1,500-mile typical range). Orange = regional jets (500-mile typical range). Purple = turboprops (125–275-mile typical range). TOL = takeoff and landing.
