The unit cannot be autorotated.
The GEN H-4's blades are semifixed.
In order to maintain balance, the unit uses a redrag hinge, but it is not designed to change pitch. As such, even if autorotation is initiated, the final flare cannot be performed, preventing safe landing.
However, autorotation landings in other helicopters is also considered extremely difficult. In an emergency situation, instead of using autorotation, we are planning for a projection parachute to be used for emergency landings.
This varies greatly based on the weight of the pilot. It also varies based on temperature, air pressure, and altititude. Our tests in Nagano have been of 10 minute flights. The unit can fly continuously for 30 minutes.
