Abstract:

According to ICAO's standard of Landing and Take-off cycle,the aircraft's paths of landing and take-off in airports are simplified . The process to calculate the pollutant emission index(EI)of aircraft emissions has been got in the original work,combined with fuel flow(F)during process of the aircraft landing and take-off,the emission intensities of approach,taxi,take-off and climb are calculated. Based on the Gaussian point source diffusion formulation,the line source diffusion model is integrated,with correction of the parameters the distribution model of aircraft emission in the airport is established.

Key words: Gaussian dispersion model, airport, aircraft emission
