AIRPORT PM_(10) EMISSIONS: DEVELOPMENT OF A FIRST ORDER APPROXIMATION (FOA) METHODOLGY FOR AIRCRAFT AND AIRPORT PARTICULATE MASS EMISSIONS

摘要

The application the FOA-Leeds method for PM_(10) estimation at airports was undertaken using a small regional airport as an example. Some further justification of the FOA-Leeds method is also given using the EU PartEmis data together with some industrial gas turbine measurements of particulate mass. The ICAO LTO cycle is appropriate to large airport but not to smaller regional airport as the aircraft movement times are much shorter in smaller airports. Data is presented for observed taxi, take off, climb out and approach times and it is shown that taxi times are much shorter than in the ICAO LTO and take Off times are shorter in modern aircraft. This data was applied to the annual operations of a regional airport and every plane using the airport was identified and their engines. The ICAO LTO cycle database was used to determine the EI in each mode and the SN, but the measured LTO times were used to determine the total mass emissions. These were compared with the ICAO LTO cycle times and the estimated PM_(10) mass emissions were significantly lower. The total aircraft movements for the summer period were analysed and the total PM_(10) mass emissions were estimated.
