- Chapter 7: Helicopter Performance › Sample Hover Problem 3 › Climb Performance
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…

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…

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…
- Chapter 11: Aircraft Performance › Climb Performance Factors › Range Performance
These are the source of range and endurance operating data included in the performance section of the AFM/POH. Cruise control of an aircraft implies that the aircraft is operated to maintain the recommended long-range cruise condition throughout the flight ... means the control of the optimum airspeed, altitude, and power setting to maintain the 99 percent maximum specific range condition. At the beginning of cruise flight, the relatively high initial weight of the aircraft requires specific values of airspeed, altitude…
- Chapter 11: Aircraft Performance › Performance Charts
Performance Charts Performance charts allow a pilot to predict the takeoff, climb, cruise, and landing performance of an aircraft. These charts, provided by the manufacturer, are included in the AFM/POH. Information the manufacturer provides on these charts has been gathered ... from test flights conducted in a new aircraft, under normal operating conditions while using average piloting skills, and with the aircraft and engine in good working order. Engineers record the flight data and create performance charts based on the behavior…
