82. Maximum noise levels
The maximum noise levels, when determined in accordance with the noise evaluation method of the Third Schedule, shall not exceed the following—(a)at the lateral full-power reference noise measurement point, 103 EPNdB for aeroplanes with maximum certificated take-off mass, at which the noise certification is requested, of 400 000 kg and over, decreasing linearly with the logarithm of the mass down to 94 EPNdB at 35 000 kg, after which the limit is constant to 8 618 kg, where it decreases linearly with the logarithm of the mass down to 88.6 EPNdB at 2 000 kg, after which the limit is constant;(b)at the flyover reference noise measurement point—(i)aeroplanes with two engines or less, 101 EPNdB for aeroplanes with maximum certificated take-off mass, at which the noise certification is requested, of 385 000 kg and over, decreasing linearly with the logarithm of the mass at the rate of 4 EPNdB per halving of mass down to 89 EPNdB, after which the limit is constant to 8 618 kg, where it decreases linearly with the logarithm of the mass at a rate of 4 EPNdB per halving of mass down to 2 000 kg, after which the limit is constant;(ii)aeroplanes with three engines, as (a) but with 104 EPNdB for aeroplanes with maximum certificated take-off mass of 385 000 kg and over;(iii)Aeroplanes with four engines or more, as (a) but with 106 EPNdB for aeroplanes with maximum certificated take-off mass of 385 000 kg and over.(c)at the approach reference noise measurement point, 105 EPNdB for aeroplanes with maximum certificated take-off mass, at which the noise certification is requested, of 280 000 kg and over, decreasing linearly with the logarithm of the mass down to 98 EPNdB at 35 000 kg, after which the limit is constant to 8 618 kg, where it decreases linearly with the logarithm of the mass down to 93.1 EPNdB at 2 000 kg, after which the limit is constant;(d)the sum of the differences at all three measurement points between the maximum noise levels and the maximum permitted noise levels specified in 73(a), (b) and (c), shall not be less than 17 EPNdB; and(e)the maximum noise level at each of the three measurement points shall not be less than 1 EPNdB below the corresponding maximum permitted noise level specified in 73(a), (b) and (c).
