Airworthiness regulations give the requirements of aircraft cabin air contaminations concentrations (carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), etc.), which are the most basic and minimum safety requirements. While, modern civil aircraft design can not only meet the airworthiness regulatory requirements, but also satisfy high level industry standards in order to improving the comfortableness of the cabin. Therefore, according to the influence of cabin air contaminations on the crew and passengers, three limit levels (safety, health and comfortable limits) of cabin air contamination conditions are defined here. Moreover, recommended three limit levels of aircraft cabin air contaminations concentrations are established, by analyzing and summarizing the current effective airworthiness regulations and industry standards requirements on cabin air contamination, such as carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), particulate contaminants?PM2.5, PM10?? and volatile organic compounds (VOCs). The results of this work can be referenced for the design of air conditioning system as well as cabin safety and comfortableness of modern civil aircraft.
