Taxiing aircraft contribute significantly to fuel burn and emissions at airports. The quantities of fuel burned as well as different pollutants, such as carbon dioxide, hydrocarbons, nitrogen oxides, sulfur oxides and particulate matter, are functions of aircraft taxi duration (along with throttle setting, number of running engines, and pilot and airline decisions regarding engine shutdowns during delays). The reduction of taxi times through improved planning of surface movements has the potential to reduce these emissions. Project 21 focuses on opportunities to reduce surface emissions through departure planning and surface movement optimization. |
