A technique is described based on simple statistics that can be used to assess the accuracy of analytical predictions compared to measurements. It is demonstrated that the approach can be applied to a broad range of problems in the area of helicopter aeromechanics, including hover and forward flight performance, blade aerodynamic and structural loads, vibratory forces, and aeroelastic/aeromechanical stability. The method described has both strengths and weaknesses, and these are shown with examples and discussed. It is also shown that there is currently a hierarchy of accuracy in aeromechanics problems, ranging from the necessarily accurate methods for performance prediction to the inaccurate and untrustworthy calculations of fixed-system vibration.
