Even though it is a small helicopter, the R-22 does not lose safety. There is nothing that could directly cause a critical problem to the flight of the helicopter. By strictly following the manual, the rotary wing aircraft becomes the safest means of transportation ever invented, second only to the elevators. Contrary to what many people imagine, the helicopter can glide after an engine crash. This maneuver is called self-rotation. The R-22 has a system called Free Wheel Clutch, with the function of disconnecting the engine from the drive shaft if it rotates slower than the rotors. The same thing happens on a bicycle, when we stop pedaling the ratchet it releases the wheel to rotate freely in one direction, but if it tries to rotate in the opposite direction or slower than the ratchet, it will lock and transfer the force to the pedals. The 2 rotors are rigidly connected by a drive shaft. In case of locking the tail rotor by shock with some object or bird, it has shear bolts, which cut off and eventually disconnect the failed tail rotor from the drive shaft, leaving the main rotor to rotate freely. After the tail rotor has stopped, it is continued to the flight in auto-rotation. The engine of the R-22 has dual magnet system, totally independent. Both are tested before flight by the pilot.
