Abstract: Methods, apparatus, and articles of manufacture to provide improved engine load models are disclosed. An example apparatus includes a model generator to generate an engine load model for an engine using flight information, weather information, and manifest information to predict a load on the engine from an engine subsystem utilization modeled for a flight. The example model generator is to incorporate the engine load model into an engine model, the engine model representing engine behavior for the flight. The example model generator is to determine a first measure of thrust from the engine and a second measure of fuel flow to the engine using the engine model with the engine load model, the engine load model to modify engine behavior by the predicted load on the engine from the engine subsystem utilization.
