1. A system for controlling a safety device for a rotary-wing aircraft, the system comprising:
a plurality of sensors, each configured to detect a motion of the rotary-wing aircraft and generate a detection value indicating the detected motion of the rotary-wing aircraft; and
a controller configured to:
determine an accident risk level during a flight of the rotary-wing aircraft based on the detection value generated from each sensor; and
control the safety device positioned at the rotary-wing aircraft to operate automatically or manually based on the determined accident risk level,
wherein, to determine the accident risk level, the controller is configured to:
compare the detection value generated from each sensor with a predetermined value; and
determine the accident risk level based on a number of the sensors outputting the detection value exceeding the predetermined value, and
wherein, to determine the accident risk level, the controller is further configured to:
determine that the accident risk level is high when the number of the sensors outputting the detection value exceeding the predetermined value exceeds a half of the number of the sensors; and
determine that the accident risk level is low when the number of sensors outputting the detection value exceeding the predetermined value does not exceed the half of the number of the sensors.
