The interpretation of extensive air shower (EAS) measurements depends on the comparison with EAS simulations. These calculations rely on hadronic interaction models which have to extrapolate into kinematical and energy regions not covered by present-day collider experiments. Therefore, it is necessary to check the reliability of the interaction models used. For the EAS simulations the program CORSIKA is used with several hadronic event generators embedded. Different observables, measured with the KASCADE experiment simultaneously for each air shower event, are investigated as well as their correlations. The consistency of the models applied is checked by comparison of experimental and simulated results.
