Low carbon emissions review in aviation engine technology for Asean airspace: a proposal

Air tranportation has been major mode of connecting role player in business supply chain and catalyst for tourism industry. Emission from aircraft engines do produce various gasses as by product of combustion. Thus in this paper the authors focus on gas turbine engine emissions in accordance to ICAO Annex 16 emission protection recommendations. Majority of the aircraft are fitted with gas turbine engines for propulsion. The United States Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) emission documents were studied. Cabon in this context is CO2 directly related to fuel consumption by the engine. The engine emission consist of NOx , HC, CO2 and smoke. However with various initiatives aircraft today 15 percent reduction in fuel burn, 40 percent lower in emission compared to a decade ago (ICAO Environmental report 2010) The FAA have launched the continuous lower energy, emissions and noise (CLEEN) program in 2010. The goal of the CLEEN program is to noise and emissions reduction by aircraft and engine technology. Another improvement was the alternative fuel deployment and development project. This project known as “Farm to Fly” and base on this initiative development three alternative jet fuels approved for aviation use by ASTM standards. FAA also developing a proposed Global Market Based Measure (GMBM) for metrics of measurement. These holistic program known as “Next Generation Air Transportation System” or NextGen. NextGen has five pillars of strategy. (US Aviation GHG reduction plan 2015)
