Situations that contribute to low G conditions
From the FAA library
- 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 ... rotor rpm, the helicopter will start to settle. If the pilot raises the collective to stop the settling, the situation will feed upon itself rapidly leading to rotor stall. There are a number of ways the pilot can recognize…
- Chapter 1: Risk Management and Single-Pilot Resource Management › Situational Awareness › Obstacles to Maintaining Situational Awareness
emphasize that routine flight operations may lead to a sense of complacency, which can threaten flight safety by reducing situational awareness. By asking about positions of other aircraft in the traffic pattern, engine instrument indications, and the aircraft’s location ... relation to references on a chart, the flight instructor can determine if the learner is maintaining situational awareness. The flight instructor can also attempt to focus the learner’s attention on an imaginary problem with the communication or navigation equipment…
- Chapter 12: Weather Theory › Wind and Currents › Wind Patterns
Wind Patterns In the Northern Hemisphere, the flow of air from areas of high to low pressure is deflected to the right and produces a clockwise circulation around an area of high pressure. This is known as anticyclonic circulation ... opposite is true of low-pressure areas; the air flows toward a low and is deflected to create a counterclockwise or cyclonic circulation. [Figure 12-10] High-pressure systems are generally areas of dry, descending air. Good weather is typically…
