8. Maximum noise levels
(1)The maximum noise levels of those aeroplanes covered by Regulation 5(1), when determined in accordance with the noise evaluation method of Second Schedule, shall not exceed the following—(a)at lateral and approach noise measurement points: 108 EPNdB for aeroplanes with maximum certificated take-off mass of 272 000 kg or over, decreasing linearly with the logarithm of the mass at the rate of 2 EPNdB per halving of the mass down to 102 EPNdB at 34 000 kg, after which the limit remains constant;(b)at flyover noise measurement point: 108 EPNdB for aeroplanes with maximum certificated take-off mass of 272 000 kg or over, decreasing linearly with the logarithm of the mass at the rate of 5 EPNdB per halving of the mass down to 93 EPNdB at 34 000 kg, after which the limit remains constant.(2)Equations for the calculation of maximum permitted noise levels as a function of take-off mass are as described in the Third Schedule of these regulations.(3)The maximum noise levels of those aeroplanes covered by regulation 5(2), when determined in accordance with the noise evaluation method in the Second Schedule, shall not exceed the following—(a)at lateral noise measurement point: 106 EPNdB for aeroplanes with maximum certificated take-off mass of 400 000 kg or over, decreasing linearly with the logarithm of the mass down to 97 EPNdB at 35 000 kg, after which the limit remains constant;(b)at flyover noise measurement point—(i)Aeroplanes with two engines or less: 104 EPNdB for aeroplanes with maximum certificated take-off mass of 325 000 kg or over, decreasing linearly with the logarithm of the mass at the rate of 4 EPNdB per halving of mass down to 93 EPNdB, after which the limit remains constant;(ii)aeroplanes with three engines: as regulation 8(3)(a) but with 107 EPNdB for aeroplanes with maximum certificated take-off mass of 325 000 kg or over;or as defined by regulation 8(1)(b), whichever is the lower;(iii)aeroplanes with four engines or more: as regulation 8(3)(a) but with 108 EPNdB for aeroplanes with maximum certificated take-off mass of 325 000 kg or over;or as defined by regulation 8(1)(b), whichever is the lower(c)at approach noise measurement point: 108 EPNdB for aeroplanes with maximum certificated take-off mass of 280 000 kg or over, decreasing linearly with the logarithm of the mass down to 101 EPNdB at 35 000 kg, after which the limit remains constant.
