Paper 16 -- AEDT GLOBAL NOX DEMONSTRATION

The Global NOx (Oxides of Nitrogen) demonstration is the first Capability Demonstrator (CD) sample problem of the Aviation Environmental Design Tool (AEDT). AEDT is intended to facilitate the analysis of tradeoffs between noise and emissions and make the evaluation of air quality and noise impact seamless between the local and global domains. This CD marks an initial step toward creating a harmonized air quality module suitable for local and global analyses by leveraging the work already invested in developing the Emissions and Dispersion Modeling System (EDMS), the System for assessing Aviation’s Global Emissions (SAGE), the Integrated Noise Model (INM), and the Model for Assessing Global Exposure from Noise of Transport Airplanes (MAGENTA). This initial CD focused on building a tool that assesses the impacts of different NOx stringencies to support the development of NOx emissions standards and highlights improvements over the previous modeling capabilities in many ways. AEDT implements Boeing Fuel Flow Method 2 (BFFM2) which allows for the use of thrust-specific emission indices corrected for atmospheric conditions, instead of relying on the sea level static certification data collected in the ICAO Aircraft Engine Exhaust Emissions Databank. BFFM2 is implemented in conjunction with a new, gate-to-gate, dynamic aircraft performance module based on the Society of Automotive Engineers’ Aerospace Information Report 1845 (SAE-AIR-1845) and EUROCONTROL’s Base of Aircraft Data (BADA). AEDT also implements input data processing enhancements to enable a more detailed fleet mix to be modeled. AEDT combines the International Official Airline Guide (IOAG) and FAA’s Enhanced Traffic Management System (ETMS) data with the CAEP-developed fleet forecast from their Forecasting and Economics Support Group (FESG) to produce a comprehensive global operations forecast. The resultant aircraft-type-specific route information, allows the results to be aggregated in multiple ways, as opposed to being limited to only assessing global performance. The methodologies used in this demonstration of AEDT capabilities are described in the paper.
