Abstract

In accordance with an exemplary embodiment, an operations support system for an engine is provided. A diagnostics unit is configured to receive engine data from the engine and to generate condition indicators based on the engine data using a thermodynamic model, the thermodynamic model being based on component maps associated with the engine. An emissions calculation unit is coupled to the diagnostic unit and configured to calculate emissions information for the engine based on the condition indicators. A graphical user interface is coupled to the emissions calculation unit and configured to display the emissions information.
