Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Low-Frequency Vibrations
Abnormal Vibration With the many rotating parts found in helicopters, some vibration is inherent. A pilot needs to understand the cause and effect of helicopter vibrations because abnormal vibrations cause premature component wear and may even result in structural failure ... With experience, a pilot learns what vibrations are normal and those that are abnormal and can then decide whether continued flight is safe or not. Helicopter vibrations are categorized into low, medium, or high frequency. Low-Frequency Vibrations Low-frequency…

Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Medium- and High-Frequency Vibrations
Medium-frequency vibrations are felt through the entire airframe, and prolonged exposure to the vibrations will result in greater pilot fatigue. Most tail rotor vibrations fall into the high-frequency range (2,100 cycles per minute or higher ... felt through the tail rotor pedals as long as there are no hydraulic actuators to dampen out the vibration. This vibration is felt by the pilot through his or her feet, which are usually “put to sleep” by the vibration…

exceeding the output of the alternator or generator, and the battery is helping to supply electrical power. This may mean the alternator or generator is malfunctioning, or the electrical load is excessive. An ammeter displays the load placed ... alternator or generator causes the load meter to indicate zero. Electrical switches are used to select electrical components. Power may be supplied directly to the component or to a relay, which in turn provides power to the component. Relays…

flight including: • Illness–Does a pilot suffer from initial symptoms, ongoing illness, or any aftereffects? Even mild symptoms may be sufficiently debilitating to create a “P” hazard. • Medication–Could any medications the pilot takes affect the flight? Both prescription ... prescription over-thecounter (OTC) drugs have side effects that can affect a pilot’s physical and mental performance. The FAA provides information regarding OTC drugs here. • Stress–Has a stressful life situation affected the pilot? Many personal or business events…

Since useful tools and sources of information may not always be readily apparent, learning to recognize these resources is an essential part of ADM training. Resources must ... only be identified, but a pilot must also develop the skills to evaluate whether there is A pilot may be tempted to make it into an airport by descending below minimums during an approach. There may be a belief that…
