The quality of cabin and cockpit air is at least as good as the quality of air in other “normal indoor environments” such as offices, schools and homes, according to a study conducted for the European Aviation Safety Agency (EASA).
No occupational exposure limits or guidelines were violated during flights conducted to assess air quality, said the study, conducted by a consortium of the Fraunhofer Institute for Toxicology and Experimental Medicine and the Hannover Medical School and released March 23 by EASA.
In-flight measurements were conducted on 69 flights between July 2015 and June 2016 using eight types of aircraft/engine configurations; of these, 61 flights were in airplanes with engine bleed air systems and eight were in Boeing 787s equipped with “bleed-free” electrical compressors.
