Operational conditions influence on aircraft engine emission and pollution inside the airport

Determination of emission indexes under real operational and meteorological conditions is actual task, as input data for models and high accurate assessment of aircraft emissions contribution to total air pollution in the vicinity of airport. Also estimation emission indexes with taking into account engine age and its maintenance allow to calculate precisely the emission inventories of airports. Analysis results of emission measurement data for aircraft engine concluded that method, which takes into account the influence of the real operational (fuel flow rate, operation period of engine/age and its maintenance) and ambient temperature on emission indices allow to get more precisely results of emission inventory of aircraft engines.
