1. A method for synthesizing output power provided by an engine, the engine comprising a compressor section, a combustor, and a turbine section in serial fluid flow communication, the method comprising:
operating the engine;
determining, during the operating of the engine, a pressure of fluid at an exit of the compressor section, a temperature upstream of the exit of the compressor section, and a fuel flow rate to the engine;
determining a synthesized value of output power provided by the engine based on a product of at least a first factor determined as a first mathematical function of the pressure and a first constant, a second factor determined as a second mathematical function of the temperature and a second constant, and a third factor determined as a third mathematical function of the fuel flow rate and a third constant; and
outputting the synthesized value of output power provided by the engine.
