60. Noise certification reference procedures-Take-off
The take-off flight path shall—(a)For the First phase be calculated taking into account the following—(i)take-off power shall be used from the brake release point to the point at which the height of 15 m (50 ft) above the runway is reached;(ii)a constant take-off configuration selected by the applicant shall be maintained throughout this first phase;(iii)the mass of the aeroplane at the brake release shall be the maximum take-off mass at which the noise certification is requested; and(iv)the length of this first phase shall correspond to the length given in the airworthiness data for a take-off on a level paved runway.(b)For the second phase be calculated taking into account the following—(i)the beginning of the second phase corresponds to the end of the first phase;(ii)the aeroplane shall be in the climb configuration with landing gear up, if retractable, and flap setting corresponding to normal climb throughout this second phase;(iii)the speed shall be the best rate of climb speed, VY; and(iv)take-off power and, for aeroplanes equipped with variable pitch or constant speed propellers, rpm shall be maintained throughout the second phase. If airworthiness limitations do not permit the application of take-off power and rpm up to the reference point, then take-off power and rpm shall be maintained for as long as is permitted by such limitations and thereafter at maximum continuous power and rpm. Limiting of time for which take-off power and rpm shall be used in order to comply with this chapter shall not be permitted. The reference height shall be calculated assuming climb gradients appropriate to each power setting used.
