  Chapter 10: Advanced Flight Maneuvers › Maximum Performance Takeoff

  maximum performance takeoff, know thoroughly the capabilities and limitations of the equipment. Also consider the wind velocity, temperature, density altitude, gross weight, center of gravity (CG) location, and other factors affecting pilot technique and the performance of the helicopter ... accomplish this type of takeoff safely, there must be enough power to hover out of ground effect (OGE) in order to prevent the helicopter from sinking back to the surface after becoming airborne. A hover power check can be used…

  approximated by assuming a direct variation with density. Actually, this assumed variation would closely approximate the effect on aircraft with high thrust-to-weight ratios. Proper accounting of pressure altitude and temperature is mandatory for accurate prediction of takeoff roll ... distance. The most critical conditions of takeoff performance are the result of some combination of high gross weight, altitude, temperature, and unfavorable wind. In all cases, the pilot must make an accurate prediction of takeoff distance from the performance data…

  Chapter 10: Weight and Balance › Control › Weight and Balance Restrictions

  temperatures, and high humidity (high density altitudes), may require a reduction in weight before flight is attempted. Other factors to consider when computing weight and balance distribution prior to takeoff are runway length, runway surface, runway slope, surface wind ... overloaded in weight. Other aircraft can be loaded in such a manner that they will be out of CG limits even though the useful load has not been exceeded. Because of the effects of an out-of-balance or overweight…

  Chapter 7: Helicopter Performance › Factors Affecting Performance › Moisture (Humidity)

  altitude, weight, and wind. The Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25 (as revised), discusses these factors in great detail. Moisture (Humidity) Humidity alone is usually not considered an important factor in calculating density altitude and helicopter ... effects of humidity on density altitude, but some manufacturers include charts with 80 percent relative humidity columns as additional information. There appears to be an approximately 3–4 percent reduction in performance compared to dry air at the same altitude…
