- Chapter 11: Helicopter Emergencies and Hazards › Low-G Conditions and Mast Bumping
Recover from a low-G situation by first gently applying aft cyclic to restore normal G before attempting to correct any roll. If turbulence is expected or encountered, reduce power and use a slower than normal cruise speed. Turbulence (where ... rotor flapping angles are already present), and higher airspeeds (where the controls are more sensitive) both increase susceptibility to low-G conditions. • Use a flight simulator to learn to recognize and experience low G conditions that result in mast bumping…
- Chapter 11: Helicopter Emergencies and Hazards › Low Rotor RPM and Rotor Stall
Other causes of a power-on low rotor rpm condition include the pilot rolling the throttle the wrong way in helicopters not equipped with a governor or a governor failure in helicopters so equipped. As the rpm decreases, the amount ... feed upon itself rapidly leading to rotor stall. There are a number of ways the pilot can recognize the low rotor rpm situation. Visually, the pilot can not only see the rotor rpm indicator decrease but also the change…
