  wide margin but with a dangerously low rpm and no power reserve. Always make the landing to a specific point and not to some general area. This point should be located well forward, away from the approach ... more confined the area is, the more essential it is that the helicopter land precisely at a definite point. Keep this point in sight during the entire final approach. When flying a helicopter near obstacles, always consider the tail rotor…

  check can be used to determine if there is sufficient power available to accomplish this maneuver. The angle of climb for a maximum performance takeoff depends on existing conditions. The more critical the conditions are, such as high-density altitudes ... calm winds, and high gross weights, the shallower the angle of climb is. In light or no wind conditions, it might be necessary to operate in the crosshatched or shaded areas of the height/velocity diagram during the beginning of this…

  Sample Hover Problem 3 Using Figure 7-6, determine what torque is required to hover. Use the following conditions: First, enter the chart at 9,500 feet pressure altitude, then move right to outside air temperature, 0 °C. From that ... point, move down to 4,250 pounds gross weight and then move left to 5-foot skid height. Drop down to read 66 percent torque required to hover. Climb Performance Figure 7-6. Torque required for cruise or level flight…

  Chapter 7: Helicopter Performance › Performance Charts › Sample Cruise or Level Flight Problem

  Atmospheric wind affects only the groundspeed, or speed at which the helicopter is moving over the Earth’s surface. Thus, the only climb performance affected by atmospheric wind is the angle of climb and not the rate of climb. When ... planning for climb performance, it is first important to plan for torque settings at level flight. Climb performance charts show the change in torque, above or below torque, required for level flight under the same gross weight and atmospheric conditions…

  Under certain conditions, sideward flight to the takeoff position may be preferred, but rearward flight may be necessary, stopping often while moving to check on the location of obstacles relative to the tail rotor. When planning the takeoff, consider ... obstructions, and forced landing areas. To help fly up and over an obstacle, form an imaginary line from a point on the leading edge of the helicopter to the highest obstacle to be cleared. Fly this line of ascent with…

  confined area gives the pilot the most distance to clear obstacles. Wind analysis also helps determine the route of takeoff. The prevailing wind can be altered by obstructions on the departure path and can significantly affect aircraft performance. There ... last report that was received by either the Automatic Terminal Information Service (ATIS) or airport tower.
