CS 29.45 General ED Decision 2003/16/RM (a) The performance prescribed in this subpart must be determined: (1) With normal piloting skill; and (2) Without exceptionally favourable conditions. (b) Compliance with the performance requirements of this subpart must be shown: (1) For still air at sea-level with a standard atmosphere; and (2) For the approved range of atmospheric variables. (c) The available power must correspond to engine power, not exceeding the approved power, less: (1) Installation losses; and (2) The power absorbed by the accessories and services at the values for which certification is requested and approved. (d) For reciprocating engine-powered rotorcraft, the performance, as affected by engine power, must be based on a relative humidity of 80% in a standard atmosphere. (e) For turbine engine-powered rotorcraft, the performance, as affected by engine power, must be based on a relative humidity of: (1) 80%, at and below standard temperature; and (2) 34%, at and above standard temperature plus 28°C (50°F). Between these two temperatures, the relative humidity must vary linearly. (f) For turbine-engine-powered rotorcraft, a means must be provided to permit the pilot to determine prior to take-off that each engine is capable of developing the power necessary to achieve the applicable rotorcraft performance prescribed in this subpart.
