Based on the International Civil Aviation Organization's standard emission model, this survey collected actual flight conditions of nine airports in Beijing-Tianjin-Hebei airport group, fully considered impact height atmospheric mixed layer, and revised operating time using US Environmental Protection Agency method to accurately estimate 2018-2019 shipping season (364 days) landing take-off cycle (LTO) air pollutant emissions list for group aircraft. The results show that total NOx, CO, SO2, HC, PM LTO are 10720.5, 3972.2, 407.8, 508.0, 53.7 t, respectively. Within these, winter spring 4290.2, 1646.7, 168.3, 220.1, 22.4 respectively; summer autumn 6430.3, 2325.5, 239.5, 287.9, 31.3 From perspective spatial distribution, Beijing Capital Airport is with largest amount pollutants discharged. Regarding highest peak at 07:00-08:00, there a medium-high level from 12:00-20:00, relatively low after 21:00. aircraft emit more NOx CO cycle, accounting least emissions. discharges different under working modes significantly different. Of all B777 unit most pollutants, B737 least, B787 circulation HC lowest.
