Analysis of LTO Cycle Emissions as Results of Aircraft Operations in the Vicinity of Torino Caselle Airport

This paper proposes a methodology based on the Boing Fuell Flow Method 2 (BFFM2) in order to assess non-CO2 emissions resulting from the analysis of real-life aircraft Landing and Take-Off (LTO) cycles. The method is validated exploiting, as case study, the operational procedures in the vicinity of Torino Caselle airport, in the north-west part of Italy. Notably, this study focuses on the analysis of the individual operational procedures, including Standard Instrument Departures (SIDs), Standard Terminal Arrivals (STARs) and Approaches, published by the Italian Air Navigation Service Provider (ENAV), in order to assess the expected level of emissions for nominal trajectories, potentially identifying those flight legs which can be more relevant in terms of impact on air quality. This may open up for suggestions about updates to the procedures themselves, according to a trade-off with actual flown distance (i.e. fuel consumption), also looking at the most congested trajectories.
