Abstract Abstract：The flutter calculation method to convensional aircraft tail wing can not be applied directly to T-tail flutter analysis due to its features in structural and aerodynamic configurations, and the effects of in-plane motion and steady aerodynamics of horizontal plane should be considered in T-tail flutter calculation. From the view point of engineering analysis for T-tail flutter, some key issues of T-tail flutter calculation are discussed in this paper, the characteristics of T-tail flutter problem and the key parameters that effect T-tail flutter properties are described. Especilly foure methods to revise the aerodynamics of T-tail in its flutter calculation are intruduced and finally some specific problems in T-tail flutter analysis that worthy of further study are emphasized
