One of the major accident causes of helicopter is collision into terrain and into near-ground obstacles. As a countermeasure to such collision risk, collision avoidance system especially for low level flight is indispensable. In this research, the obstacle alert system and the collision avoidance algorithm was developed to be integrated into AFCS. Results of evaluation using a simulator showed that the algorithm can prevent helicopter from collision with realistic level of autopilot authority. In the flight experiment conducted at Taiki Multipurpose Airfield, obstacle alert message was displayed as expected, although there was problem to be improved.
