Further Assessment of the NO x Emission from CAAC Fleet over China

  • Received Date: 10 Dec 1999

  • On the basis of CAAC timetable and route setting, and according to individual aeroplanes and aeroengines, the present paper simplified and modeled the operation of each flight. Moreover, using the popular fuel flow method and by means of the emission databanks published by ICAO and NASA,the inventory of NOx emitted from CAAC flights in April to October of 1998 was assessed. The results show that NOx emissions from current commercial airplanes over China are concentrated on some big cities. The concentrations of NOx over different cities have great differences. The NOx emissions over China have doubled comparing with 6 years ago. And the NOx emission level over several Chinese big cities is about the same as that of some big cities in developed countries at 6 years ago.
