Aircraft LTO Impacts on
Local Air Quality Examined
|
A study of landing/take-off (LTO) emissions at 325 commercial airports, 148 of which are located in ambient air quality non-attainment areas (NAAs) for ozone, CO, PM 2.5, PM 10, SO2, or NO2, found that they accounted for less than one percent of each of these emissions in the NAAs, on average. Conducted by investigators from MIT, CSSI, Inc., and Metron Aviation for PARTNER between June 2005 and May 2006, the study also determined that there were an estimated 160 incidences of PM-related premature mortality per year from ambient particulate matter exposure attributable to aircraft emissions at the 325 airports studied.
“In total, 47 counties within the United States had a PM-related premature mortality risk associated with aircraft emissions that was greater than one incidence per year. Other health impacts, such as chronic bronchitis, non-fatal heart attacks, respiratory, and cardiovascular illnesses were also associated with aircraft emissions.”
Reducing Efficiency
The project objectives were to identify the impact of aircraft emissions on air quality in NAAs, ways to promote fuel conservation measures for aviation, and opportunities to reduce air traffic inefficiencies that increase fuel burn and emissions. “The relationship between taxi-out time and emissions suggests that air traffic management initiatives have the potential to play an important role in increasing operational efficiency and, in turn, reducing emissions and fuel use at U.S. airports,” according to the report.
“To increase efficiency without adversely affecting safety, noise, and security, operational initiatives must be implemented with consideration of the larger system, and the numerous, complex interdependencies that are inherent in the system. There are no universal mitigation strategies for operational efficiency, and a single technology or procedure will not be applicable at all U.S. airports.”
