In this study, a linear mathematical model representing longitudinal flight dynamics of an airplane is developed and responses of the aircraft during a microburst encounter are investigated. The effects of microburst that are acting on the aircraft are attempted to be suppressed with the elevator control surface of the aircraft, which is controlled by Linear Quadratic Regulator method. To illustrate the effectiveness of the proposed control method, numerous numbers of simulation studies is performed. As a result of the simulations, it is observed that effects of microburst on the pitching angle and altitude are significantly attenuated by the proposed control method. In addition, it is confirmed that the elevator control surface movement which provides the necessary controller input is within the physical capabilities of the aircraft.
