Frequency‐domain system identification techniques were used to develop a series of mathematical models of the Bell 206 helicopter, each valid at different flight conditions. The models were combined and “stitched” together to produce a continuous full flight envelope model of the helicopter. The model was implemented in a simple simulator and evaluated by several pilots, all flight qualified in this helicopter. It was the opinion of the pilots that the simulation is a good representation of the aircraft for all tasks of interest.
