An estimation and alignment method of wing position and orientation was presented to deal with the two different accuracy requirements in order to solve the inconsistency of the evaluation basis for the positional accuracy of fuselage-wing joints and the height accuracy of wing level-measuring points in aircraft digital assembly. A decomposition strategy of problem solving was adopted to solve the difficulty of dispose uniformly. The wing position and orientation were first estimated and aligned to insure the positional accuracy of the joints based on the joint measurement data. The allowable adjustment range of wing orientation was computed according to the joint allowance for finish machining. Then the minimum adjustment angle was calculated in accordance with the height difference of the level-measuring points. The application results show that the method is feasible．
