We propose Gust Error Method (GEM), improving aircraft parameter identification under stochastic gusts by modelling process noise with a low-rank decomposition. Simulations show reduced residual correlation and improved estimates. GEM separates disturbance structure, intensity, and realization, providing a practical method to account for unknown gust input during flight test.
