Trending Analysis in Aviation Emissions and Type Certification

Due to the global warming and industrial environment pollution, many effected issues have been implemented to achieve the improvements. The international standards limiting the emissions from turbojet and turbofan aircraft engines are contained in International Civil Aviation Organization (ICAO) Annex 16 Volume II to the Convention on ICAO. The Committee on Aviation Environmental Protection (CAEP), led by ICAO, has progressively strengthened the requirements for aircraft emissions, with detailed classifications of aircraft emission components, and continuously improvements of the emission component test validation procedures and data processing methods. This paper summarizes the revision process of ICAO Annex 16 Volume II, and makes a tentative discussion on the trend of the airworthiness regulations on emission requirements with the comparisons with the technological development paths of OEMs. Meanwhile, the impact of the revised regulations on the emission certification process is analyzed to provide a reference for the domestic commercial aviation products airworthiness certification process.
