Probability of Detection (POD) studies are typically conducted on EDM notches, 'manufactured' crack specimens, or actual in-service crack specimens. The purpose of this paper is the education of the aerospace community in the subtle differences and benefits of using each specimen type. Data from previous POD studies are compared to data from teardown of a retired passenger aircraft, resulting in POD data from in-situ defects. Analysis of this data reveals similarities and differences between signals for four (4) types of specimens and four (4) nondestructive inspection (NDI) methods. Additionally, the paper provides an awareness of the assumptions used in each type of POD study, and potential consequences of violating such assumptions.
