Edition: 2026-03-03 · In force
16. 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 and decreasing linearly with the logarithm of the mass down to 94 EPNdB at 35 000 kg, after which the limit remains constant(b)at 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 and decreasing linearly with the logarithm of the aeroplane mass at the rate of 4 EPNdB per halving of mass down to 89 EPNdB, after which the limit is constant(ii)aeroplanes with three engines under regulation 16(b)(i) 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, under regulation 16(b)(i) but with 106 EPNdB for aeroplanes with maximum certificated take-off mass of 385 000 kg and over;(c)at approach reference noise measurement point105 EPNdB for aeroplanes with maximum certificated take-off mass, at which the noise certification is requested, of 280 000 kg or over, and decreasing linearly with the logarithm of the mass down to 98 EPNdB at 35 000 kg, after which the limit remains constant; and(d)equations for the calculation of maximum permitted noise levels as a function of take-off Mass are specified under the Third Schedule to these Regulations.
