The advanced emission model (AEM) is a standalone application, developed and maintained by our Innovation Hub in Brétigny, that estimates aircraft emissions and fuel burn. In addition to this, AEM analyses flight profile data on a flight by flight basis, for air traffic scenarios of almost any scope, from local studies around airports to global aircraft emissions.
AEM can estimate:
- the mass of fuel burned by the main engines of a specified type of aircraft with a specified type of engine flying a specified 4D trajectory;
- the corresponding masses of certain gaseous and particulate emissions which are produced by the burning of that fuel.
The gases whose masses can be estimated include carbon dioxide (CO2), water vapour (H2O), the oxides of nitrogen (NOx) and sulphur (SOx), unburnt hydrocarbons (HC), carbon monoxide (CO), volatile organic compounds (VOCs), and other organic gases (OGs).
