  Application of the collective that is too abrupt when departing the surface, causing rpm and heading control errors. Crosswind Considerations During Takeoffs If the takeoff is made during crosswind conditions, the helicopter is flown in a slip during the early ... stages of the maneuver. [Figure 9-13] The cyclic is held into the wind a sufficient amount to maintain the desired ground track for the takeoff. The heading is maintained with the use of the antitorque pedals. In other words…

  requiring the use of excessive power during the termination. 4. Approaching too fast, causing a hard landing 5. Not maintaining skids aligned with direction of travel at touchdown. Any movement or misalignment of the skids or gear can induce dynamic ... rollover Crosswind During Approaches During a crosswind approach, crab into the wind. At approximately 50-100 feet of altitude, use a slip to align the fuselage with the ground track. The rotor is tilted into the wind with cyclic pressure…

  bank angle and rate-of-turn must be reduced gradually to ensure that upon completion of the turn, the crosswind ground track continues to be the same distance from the edge of the field. Upon completion of the turn ... helicopter should be level and crabbed into the wind in order to maintain the proper ground track. Keep in mind that in order to maintain proper ground track the helicopter may have to be flown almost sideways depending…

  Then, pick two points of in-line reference in the direction of sideward hovering flight to help maintain the proper ground track. These reference points should be kept in line throughout the maneuver. [Figure 9-8] Begin the maneuver from ... side in which the movement is desired. As the movement begins, return the cyclic toward the neutral position to maintain low groundspeed—no faster than a brisk walk. Throughout the maneuver, maintain a constant groundspeed and ground track with cyclic…

  Chapter 5: Aerodynamics of Flight › Ground Effect

  Figure 5-16. Ground effect changes airflow. Ground effect also alters the thrust required versus velocity. Since induced drag predominates at low speeds, the reduction of induced drag due to ground effect will cause a significant reduction of thrust required ... downwash, and wingtip vortices, there may be a change in position (installation) error of the airspeed system associated with ground effect. In the majority of cases, ground effect causes an increase in the local pressure at the static source…

  With the main wheels acting as a pivot point and the greater surface area exposed to the crosswind behind that pivot point, the airplane tends to turn or weathervane into the wind. The relative wind acting on an airplane during ... acts in the direction the air mass is traveling. It has a headwind component acting along the airplane’s ground track and a crosswind component acting 90° to its track. The other factor is the wind induced by the forward…
