A method and apparatus for calibrating a set of transducers (120). In one illustrative embodiment, an apparatus comprises a target device (137), an imaging device (139), and a calibrator (136). The imaging device (139) generates a plurality of images (140)...

A highly reliable aerodynamic coefficient estimate can be computed, and computation of this aerodynamic coefficient estimate enables accurate detection of control surface failure/damage while reducing a discomfort for passengers. A deflection angle command...
