In this research, a dynamic simulator software has been designed to calculate the time varying load factor acting on an aircraft wing and on a horizontal tail relation to elevator deflection angle. The related loading equations were extracted and solved by MATLAB software and were presented as a GUI software. By introducing time varying angles of the elevator deflection in each flight maneuver and the necessary derivatives, the dynamic load factor on the wing and on horizontal tail were calculated with respect to time. In derivation of equations, the moment due to elevator camber, the effect of time lag in downwash, and the change in tail angle due to rotation were also considered. Comparing the results with the analytical ones confirms the reliability of the software. This software provides a rational approach in aircraft loading calculations that is applicable for structural design of the wing and the horizontal tail, as well as for conformity with the requirements of aviation regulations for loading, to obtain an airworthiness certificates.
