A wing and tail are geometrically similar, while tail area is one-third of the wing area and distance between two aerodynamic centres is equal to wing semi-span (b/2). In addition, following data is applicable: âˆˆ_Î± = 0.3, C_L = 1.0, C_{L_Î±} 0.08/ deg., c = 2.5 , b = 30m , C_{M_ac} = 0, Î·_t = 1. The symbols have their usual aerodynamic interpretation.

The angle of incidence of tail to trim the wing-tail combination for a 5% static margin is
