Anotace

This specification covers requirements and corresponding test methods for airplane aeroelasticity. It requires that the airplane be free from flutter, control reversal, and divergence for any condition of operation within the limit V-n (velocity versus load factor) envelope and at all speeds up to the speed specified for the selected method. In addition, adequate tolerances must be established for quantities which affect flutter, including speed, damping, mass balance, and control system stiffness. The natural frequencies of main structural components must be determined by vibration tests or other approved methods.
