Edition: 2026-03-03 · In force
33. Maximum noise levels
The maximum noise levels, when determined in accordance with the noise evaluation method in Third Schedule, shall not exceed the following—(a)at lateral reference noise measurement point: 96 EPNdB constant limit for aeroplanes with maximum take-off mass, at which the noise certification is requested, up to 34 000 kg and increasing linearly with the logarithm of aeroplane mass at the rate of 2 EPNdB per doubling of mass from that point until the limit of 103 EPNdB is reached, after which the limit is constant;(b)at flyover reference noise measurement point: 89 EPNdB constant limit for aeroplanes with maximum take-off mass, at which the noise certification is requested, up to 34 000 kg and increasing linearly with the logarithm of aeroplane mass at the rate of 5 EPNdB per doubling of mass from that point until the limit of 106 EPNdB is reached, after which the limit is constant;(c)at approach reference noise measurement point: 98 EPNdB constant limit for aeroplanes with maximum take-off mass, at which the noise certification is requested, up to 34 000 kg and increasing linearly with the logarithm of aeroplane mass at the rate of 2 EPNdB per doubling of mass from that point until the limit of 105 EPNdB is reached, after which the limit is constant; and(d)equations for the calculation of maximum permitted noise levels as a function of take-off mass are specified in the Third schedule of these Regulations.
