Advanced trainer plays an important role in preparing pilots before they flew their own fighter aircraft. In general, trainer aircrafts are designed with a marginal stability to resemble a fighter characteristic. But, to control the aircraft on a steady condition, stability augmented system is needed. Furthermore, to assist aircraft control, a tracking controller is also designed. In this research, a stability augmented system for longitudinal axes and a tracking controller for flight path angle will be designed an advanced trainer. SIAI-Marchetti S.211 will be used as a study case. An automatic control system designed will be done on three conditions, there are power approach, normal cruise, and high cruise. From an open-loop analysis it was found that the plane was unstable on all conditions under review. To stabilize them, then a stability augmentation system is designed using pole placement method with the poles selection are based on the value of damping ratio from MIL-SPEC requirements. Then a tracking controller for a flight path angle is designed with the selection of poles are obtain through iteration process. The simulation results shown that the designed systems are able to keep the aircraft stability as well as to follow the given flight path angle reference but cannot keep the speed change under normal operation condition because only the elevator deflection input is modelled.
