                         connected to several computing areas, such as computer 
                         aerodynamics, computerized control of aircraft, ground segment 
                         software, and flight simulators. Flight simulators are being 
                         largely used to increase the safety of operations. In order that 
                         the simulators have a good adherence to reality, they need to be 
                         calibrated, that is, identify the parameters that make the 
                         simulation as close as possible to the real dynamic. After these 
                         parameters are identified, the simulator is ready to be used to 
                         evaluate rockets and aircraft, as well as in pilot training. 
                         Determining these parameters, which characterizes the aerodynamic 
                         behavior of the aircraft, can be formulated as an optimization 
                         problem. One of the goals of this work is to calibrate the 
                         simulator of a helicopter dynamics using a new meta-heuristic 
                         named MPCA (Multiple Particle Collision Algorithm). The results 
                         were compared to the ones found using a genetic algorithm. 
                         However, an analysis of the flight dynamics is also relevant so 
                         that the simulator can represent the response of the aircraft. The 
                         second goal of this work is to predict the flight dynamics of a 
                         simulator. At this stage, the problem of predictability was 
                         formulated as a classification problem. A bred vector based 
                         technique was employed to evaluate a non-linear dynamic system, 
                         and neuro-fuzzy classifiers were used to identify predictability 
                         classes. The application of bred vectors methodology focused on 
                         the dynamics of the rotor of a helicopter.",
