The methodology was based on a comparison of fuel burn and emission production in a Fixed Route against a Free Route Environment. The Advanced Emission Model (AEM3) developed at the EUROCONTROL Experimental Centre has been used to estimate aviation emissions and fuel burn. An improved version (EEC-BM2) of the the Boeing Method2 (BM2) lead to more reliable in-flight NOx emission estimations.
FRAP (The Free Route Airspace Project) - Environmental Benefit Analysis
This study aims to analyse the environmental effect of the Free Route Airspace use. Investigations have been made especially for reduction in fuel burn, CO2, H2O and NOx emissions.
