System and method for monitoring health of airfoils

A method for monitoring the health of one or more blades, comprising:

• determining a delta TOA corresponding to each of the one or more blades based upon respective actual time of arrival (TOA) of the one or more blades by a processing subsystem;
• determining one or more coefficients based upon one or more operational data by the processing subsystem;
• determining effects of the one or more operational data on the respective actual TOA by utilizing the one or more coefficients and the one or more operational data;
• determining a normalized delta TOA corresponding to each of the one or more blades by removing the effects of the one or more operational data from the delta TOA by the processing subsystem;
• and
• determining a corrected delta TOA corresponding to each of the one or more blades by removing effects of reseating of the one or more blades from the normalized delta TOA by the processing subsystem.
