We present in this study an analysis of trajectories for a subsonic uninhabited aerial fixed wing vehicle. This study constitutes a preliminary stage in the design of a path planner. The UAV mission is made of elementary trajectories, where we can differentiate two types of these: 'trimming' trajectories or configurations, such as rectilinear straight and level turn flights, and 'nontrimming' trajectories, when the UAV leaves a trim configuration to reach another. After definition of the constraints of under-actuation, we study two examples of nontrim trajectories, for this we consider two essential maneuvers: the change in the flight path angle during a symmetrical flight, and the transition between a straight-level flight and a horizontal turn in nonsymmetrical mode.
