  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 ... 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 of the aircraft during the test flights. By using these performance charts…

  Performance (Section 5) The performance section contains all the information required by the regulations and any additional performance information the manufacturer determines may enhance a pilot’s ability to operate the helicopter safely. Although the performance section ... limitation section and is therefore not a limitation, operation outside or beyond the flight-tested and documented performance section can be expensive, slightly hazardous, or outright dangerous to life and property. If the helicopter is certificated under 14 CFR part…

  provide more detailed information about the various previously mentioned procedures. To avoid missing important steps, always use the appropriate checklists when available. Consistent adherence to approved checklists is a sign of a disciplined and competent pilot. Performance (Section ... Performance section contains all the information required by the aircraft certification regulations and any additional performance information the manufacturer deems important to pilot ability to safely operate the aircraft.

  Chapter 7: Helicopter Performance › Performance Charts › Height/Velocity Diagram

  Performance Charts In developing performance charts, aircraft manufacturers make certain assumptions about the condition of the helicopter and the ability of the pilot. It is assumed that the helicopter is in good operating condition, calm wind, and the engine ... average flying abilities. Average means a pilot capable of doing each of the required tasks correctly and at the appropriate times. Using these assumptions, the manufacturer develops performance data for the helicopter based on actual flight tests. However, they…

  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…

  Chapter 11: Aircraft Performance › Performance Charts › Climb and Cruise Charts

  Climb and Cruise Charts Climb and cruise chart information is based on actual flight tests conducted in an aircraft of the same type. This information is extremely useful when planning a cross-country flight to predict the performance and fuel ... consumption of the aircraft. Manufacturers produce several different charts for climb and cruise performance. These charts include everything from fuel, time, and distance to climb to best power setting during cruise to cruise range performance. The first chart to check…
