36. Noise certification reference procedures-Take-off
The take-off flight path shall be calculated as follows—(a)average take-off power shall be used from the start of take-off to the point where at least the height above runway level shown below is reached. The take-off power used shall be the maximum available for normal operations as scheduled in the performance section of the aeroplane flight manual for the reference atmospheric conditions given in regulation 35(5)—(i)aeroplanes with two engines or less — 300 m (984 ft);(ii)aeroplanes with three engines — 260 m (853 ft);(iii)aeroplanes with four engines or more — 210 m (689 ft);(b)upon reaching the height specified in a) above, the power shall not be reduced below that required to maintain—(i)a climb gradient of 4 per cent; or(ii)in the case of multi-engined aeroplanes, level flight with one engine inoperative;whichever power is the greater;(c)the speed shall be the all-engines operating take-off climb speed selected by the applicant for use in normal operation, which shall be at least V2 + 19 km/h (V2 + 10 kt) and which shall be attained as soon as practicable after lift-off and be maintained throughout the take-off noise certification test;(d)a constant take-off configuration selected by the applicant shall be maintained throughout the take-off reference procedure except that the landing gear may be retracted; and(e)the mass of the aeroplane at the brake release shall be the maximum take-off mass at which the noise certification is requested.
