Design of a Haptic Helicopter Trainer for inexperienced pilots

This paper investigates the effectiveness of a novel method of training for helicopter pilots, with flight simulators. A software trainer based on haptic force-feedback was implemented, namely the Haptic Helicopter Trainer (HHT). The HHT is an extension of an existing automated trainer based on a Optimal Control pilot Model. With the addition of a force-feedback, the HHT is able to mimic the action of an instructor pilot on dual controls. To test the effectiveness of the HHT with respect to other types of training, an experiment was performed in a fixed-based helicopter simulator with three groups of participants: one group trained with the HHT, one group trained with the automated trainer and a control group. The training was carried out as a realistic flight lesson, divided in phases to bring the student pilots to satisfying skill levels. Results showed that the designed training phases are effective for learning how to stabilize the helicopter model. Moreover, the group trained with the HHT achieved better performances than the other groups, proving the effectiveness of the haptic force-feedback in the training of inexperienced helicopter pilots.
