Radial Basis Function (RBF) neural network-based parameter estimation of coefficients from flight data is a promising approach that does not require solving a traditional analytical approach. This method, which is based on the Black Box concept, can be used to generate a longitudinal flight dynamic model of an aircraft. In this paper, the RBF-Delta method is used to estimate the control and stability derivatives of the HFB-320 aircraft. Comparison of the results has been done using the Least-Square, Delta, and ANFIS Delta methods, and the RBF-Delta method is shown to be the most robust.
