Influence of low-noise departure and approach procedures on low-altitude NOx emissions

Abstract

An overview on low-noise departure and approach procedures is given and potential effects on noise are presented. Fuel consumption and NOx emissions of selected procedures are analysed based on simulation results for a modern single aisle aircraft and using DLR’s aircraft and engine performance software. Further results are presented for aircraft with ultra high bypass ratio engines in order to assess the potential influence of engine technology on fuel consumption and NOx emissions in the vicinity of airports
