Innovative organizations have begun to use fixed-wing Unmanned Aerial Vehicles (UAVs) for healthcare delivery since they can fly faster and provide a proper solution in locations with difficult access or unsafe to human life. Moreover, they assure greater utility and better cost effectiveness than manned aircraft. However, the wind affects both the longitudinal and the lateral variables of the fixed-wing UAV contributing to its nonlinear and due to such external disturbances the UAV can fail its mission. Therefore, this review paper discusses on effects of wind disturbances on navigation of fixed-wing UAV. Full nonlinear equations of motion by including the effects of the wind on the fixed-wing UAV performance are developed. Also an overview of different approaches is presented.
