Description: The urgency of the issue of measurement and non-destructive testing of aircraft. The analysis methods for non-destructive testing. It is proved that the receipt of the complete information and its evaluation of control objects is impossible without the use of improved methods for the identification and detection of singular points (roots) of the dynamic system. It is shown that this problem often solved by indices of singular points. A study of indices of singular points on the example of the observed structural and information portraits of measurement and non-destructive testing.
Keywords: measurement, aviation technology, identification, index of singular points
