PART 29--AIRWORTHINESS STANDARDS: TRANSPORT CATEGORY ROTORCRAFT--Table of Contents
 
                            Subpart B--Flight
 
Sec. 29.45  General.

    (a) The performance prescribed in this subpart must be determined--
    (1) With normal piloting skill and;
    (2) Without exceptionally favorable 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 
percent 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 percent, at and below standard temperature; and
    (2) 34 percent, at and above standard temperature plus 50  deg.F.

Between these two temperatures, the relative humidity must vary 
linearly.
    (f) For turbine-engine-power rotorcraft, a means must be provided to 
permit the pilot to detemine prior to takeoff that each engine is 
capable of developing the power necessary to achieve the applicable 
rotorcraft performance prescribed in this subpart.
