Abstract : UAV(Unmanned Aerial Vehicle) has become one of the most popular military/commercial aerial robots in the new millennium. In spite of all the advantages that UAVs inherently have, it is not an easy job to develop a UAV because it requires very systematic and complete approaches in full development envelop. The ground test and evaluation phase has the utmost importance in the sense that a well-developed system can be best verified on the ground. In addition, many of the aircraft crashes in the flight tests were resulted from the incomplete development procedure. In this research, a verification procedure of the whole airborne integrated system was conducted including the flight management system. An airborne flight control computer(FCC) senses the external environment from the peripheral devices and sends the control signal to the actuating system using the assigned control logic and flight test strategy. A ground test station controls the mission during the test while the downlink data are transferred from the flight management computer using the serial communication interface. The pilot control box also applies additional manual actuating commands. The whole system was tested/verified on the wind-tunnel system, which gave a good pitch control performance with a pre-specified flight test procedure. The ground test system guarantees the performance of fundamental functions of airborne electronic system for the future flight tests.
