  • Chapter 8: Ground Procedures and Flight Preparations › Safety in and Around Helicopters › After Landing and Securing

    danger or see the rotors turning. Passengers should remain in the helicopter with their seats belts secured until the rotors have stopped turning. During the shutdown and postflight inspection, follow the manufacturer’s checklist. Any discrepancies should be noted…

  • Chapter 1: Introduction to the Helicopter › Controlling Flight › Throttle

    Throttle Helicopter rotors are designed to operate at a specific rpm. Figure 1-11. The throttle control mounted at the end of the collective control. The throttle controls the power produced by the engine, which is connected to the rotor ... engine power to keep the rotor rpm within allowable limits to produce enough lift for flight. In single-engine helicopters, if so equipped, the throttle control is typically a twist grip mounted on the collective control, but it can also…

  • Chapter 11: Helicopter Emergencies and Hazards › Autorotation › Technique (How to Practice)

    decreases to the desired groundspeed—usually the lowest possible speed (position 4)—move the cyclic forward to place the helicopter in the proper attitude for landing. This action gives the student an idea of airframe attitude to avoid, because ... pilot should never allow ground contact unless the helicopter is more nose-low than that attitude. Limiting the flare to that attitude may result in slightly faster touchdown speeds but will eliminate the possibility of tail rotor impact on level…

  • Chapter 11: Helicopter Emergencies and Hazards › VFR Flight into Instrument Meteorological Conditions

    simple procedural exit, and is unlike flight training by reference to while in Visual Meteorological Conditions (VMC). Most training helicopters are not equipped or certified to fly under Instrument Flight Rules (IFR). Therefore, General Aviation (GA) helicopter pilots ... have the benefit of flight in actual Instrument Meteorological Conditions (IMC) during their flight training. Helicopter pilots that encounter IIMC may experience physiological illusions which can lead to spatial disorientation and loss of aircraft control. Even with some instrument training…

  • Chapter 10: Advanced Flight Maneuvers › Slope Operations › Technique

    Technique Refer to Figure 10-6. At the termination of the approach, if necessary, move the helicopter slowly toward the slope, being careful not to turn the tail upslope. Position the helicopter across the slope at a stabilized hover headed ... into the wind over the intended landing spot (frame 1). Downward pressure on the collective starts the helicopter descending. As the upslope skid touches the ground, hesitate momentarily in a level attitude, then apply slight lateral cyclic in the direction…

    discrepancies before flight. Verify ignition OFF. Drain water from fuel tank sump and/or water trap (if fitted). 3. Inspect carburetor rubber socket or flange for cracks and verify secure attachment. 4. Inspect carburetor float chamber for water and dirt ... Verify security and condition of intake silencer and air filter. 6. Verify security of radiator mounting. Inspect radiators for damage and leaks. 7. Verify coolant level in overflow bottle and security of cap. 8. Verify coolant hoses for security…
