This work presents an analytical redundancy-based method to detect oscillatory faults in flight control systems. In this context, the focus is to evaluate wavelet transforms applied as a signal processing method on residuals generated by observers in a system-level perspective. The results demonstrate that the proposed approach achieved reliable fault detection within three cycles of fault onset.
