  Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Landing—Stuck Neutral or Right Pedal

  decision to land or go around has to be made prior to any throttle reduction. Using airspeeds slightly above translational lift may be helpful to ensure that the nose does not continue yawing to the right. If a go-around ... required, increasing the collective too much or too rapidly with airspeeds below translational lift may cause a rapid spinning to the right…

  Chapter 7: Helicopter Performance › Factors Affecting Performance › Winds

  Winds Wind direction and velocity also affect hovering, takeoff, and climb performance. Translational lift occurs any time there is relative airflow over the rotor disk. This occurs whether the relative airflow is caused by helicopter movement or by the wind ... Assuming a headwind, as wind speed increases, translational lift increases, resulting in less power required to hover. The wind direction is also an important consideration. Headwinds are the most desirable as they contribute to the greatest increase in performance. Strong…

  Chapter 9: Basic Flight Maneuvers › Normal Takeoff from the Surface › Technique

  Normal takeoff from the surface is used to move the helicopter from a position on the surface into effective translational lift and a normal climb using a minimum amount of power. If the surface is dusty or covered with loose ... ground, use the cyclic, as necessary, to begin forward movement as altitude is gained. Continue to accelerate. As effective translational lift is attained, the helicopter begins to climb. Adjust attitude and power, if necessary, to climb in the same manner…

  helicopter became very difficult to control. (At this point, the pilot must increase airspeed in order to maintain translational lift.) Since the CG was aft of limits, she needed to apply more forward cyclic than usual. As she approached ... potential vortex ring state situation if she tried to trade airspeed for altitude and lost effective translational lift (ETL). Therefore, it did not appear that she would be able to terminate the approach in a hover. The pilot decided…

  cyclic, and trim with antitorque pedals. The helicopter should be kept in trim just prior to loss of effective translational lift (approximately 25 knots). Below 100 feet above ground level (AGL), the antitorque pedals should be adjusted to align ... position the helicopter over the intended landing area. Therefore, the approach must stop at that point. Loss of effective translational lift occurs higher in a steep approach (position 3), requiring an increase in the collective to prevent settling, and more…
