More than 79 [34] power-off conversions from airplane mode to helicopter mode were made across 10 flight hours. During these tests, it was found that the minimum operating requirements for successful autorotation include the altitude being 3,000 ft (910 m), and that the system keeps rotor rpm above the minimum 70% for stable recovery.
