This work investigates the propagation of CFD numerical uncertainties in aerodynamic coefficients and the role of their cross-correlations. Using Richardson extrapolation and sensitivity analysis, it quantifies how correlated errors affect uncertainty in derived quantities such as aerodynamic efficiency and center-of-pressure location.
