SECTION 6. EMERGENCY PROCEDURES
Contents
1 Low RPM Condition
Low rotor RPM is a dangerous condition that can occur when RPM is not carefully monitored or maximum power limitations are not observed. If the RPM is allowed to decay too far, recovery may be impossible. This aircraft is equipped with a low RPM warning system consisting of a warning light and a horn. The light and horn will activate when rotor RPM is below 93% whenever the collective is not full down. In the event of a low RPM condition, the pilot should simultaneously apply full power and lower the collective until normal RPM is achieved. If the helicopter is too low or over unsuitable terrain, the pilot can attempt to "milk" the collective, with small up-down movements of the collective in an attempt to recover rotor RPM. However, the best approach is to not get into a low RPM condition in the first place.
2 Vortex Ring State
Vortex ring state occurs when a helicopter descends into its own downwash resulting in a loss of lift. It can occur when attempting to apply power during a vertical descent. To recover, the pilot should lower the collective and apply forward cyclic to regain airspeed. Since the recovery can require a significant loss of altitude, the best practice is to avoid encountering this condition, particularly when close to the ground. Practice vortex ring state recovery should be performed with sufficient altitude to be able to complete the maneuver. See SECTION 8 for a more complete description of vortex ring state.
