  Chapter 5: Rotorcraft Flight Manual › Operating Limitations (Section 2) › Powerplant Limitations

  Powerplant Limitations The powerplant limitations area describes operating limitations on the helicopter’s engine including such items as rpm range, power limitations, operating temperatures, and fuel and oil requirements. Most turbine engines and some reciprocating engines have a maximum power ... Figure 5-3. Markings on a typical dual-needle tachometer in a reciprocating-engine helicopter. The outer band shows the limits of the superimposed needles when the engine is turning the rotor. The inner band indicates the power-off limits…

  attachment point is directly under the CG of the aircraft. Weight Limitations Weight limits are necessary to guarantee the structural integrity of the helicopter, enable pilots to predict helicopter performance and insure ... aircraft controllability. Although aircraft manufacturers build in safety factors, a pilot should never intentionally exceed the load limits for which a helicopter is certificated. Operating below a minimum weight could adversely affect the handling characteristics of the helicopter. During single…

  required. Consult the Rotorcraft Flight Manual (RFM) or Pilot’s Operating Handbook (POH) for the specific limitations of the helicopter being flown. Be aware of any abnormal vibration or mast bumping that signals maximum cyclic deflection. If helicopter mast moment ... slope limits are reached before the helicopter is firmly on the ground, return the helicopter to a hover. Select a new area with a lesser degree of slope. In most helicopters with a counterclockwise rotor system, landings can be made…

  great detail. Moisture (Humidity) Humidity alone is usually not considered an important factor in calculating density altitude and helicopter performance; however, it does contribute. There are no rules of thumb used to compute the effects of humidity on density altitude ... percent seems insignificant, it can be the cause of a mishap when already operating at the limits of the helicopter…

  enhance safety of flight. Chapter 6: Weight and Balance It is vital to comply with weight and balance limits established for helicopters. Operating above the maximum weight limitation compromises the structural integrity of the helicopter and adversely affects performance. Balance ... small as three inches can dramatically change a helicopter’s handling characteristics. Operating a helicopter that is not within the weight and balance limitations is unsafe.

[Figures 8-1 and 8-2] The engineers who design a helicopter determine the amount of cyclic control authority that is available, and establish both the longitudinal ... Typical helicopter datum, flight stations, and butt line locations. If the CG is ahead of the forward limit, the helicopter tilts and the rotor disk has a forward pull. To counteract this and maintain a stationary position, rearward cyclic stick…
