simulation activities. It is a process where the aerodynamics, stability and control of the airframe are simulated with software and hardware integration. Figure 4: System Integration, software & hardware in-the-loop (SIL/HIL) and flight testing Figure 4: System Integration, software & hardware in-the-loop (SIL/HIL) and flight testing In flight testing, the auto stabilizer performance based on the SAS and CSAS design is tested and evaluated. The other systems such as Airborne System, Ground Control System (GCS) and Flight Safety System that are being integrated into the UAV system must also be tested together during the flight testing. The final outcome of the design process plus the SIL/HIL testing will be a well-designed UAV prototype. This design process could be used as a guideline especially for UAVs that are classed as more than the micro UAVs, such as the Figure 5: Life-cycle of UAV 49
