Estimation of aircraft pollution emissions based on QAR data

Research on aircraft fuel consumption is a vital aspect in the quest to reduce flight costs, while also considering aircraft pollutant emissions for emission control and environmental evaluation purposes. This study presents a comprehensive overview of the calculation method for engine pollutant emissions. Utilizing existing Quick Access Recorder (QAR) data, a case study is conducted to estimate both fuel consumption and the emission levels of gaseous pollutants, namely NO
X
, CO, HC, and CO
2
, throughout a Landing and Takeoff (LTO) cycle of the flight. Furthermore, the distribution of each gaseous pollutant across various LTO flight stages is determined. The findings indicate that utilizing real-time QAR data yields pollutant emission estimates that align closely with actual values. Based on these estimated results, strategies for controlling pollutant emissions are proposed, offering valuable insights for aircraft emission reduction and environmental assessment.
