This standard specifies a method for the calculation of aircraft noise exposure occurring in the vicinity of airfields. The standard is not applicable to water aerodromes.
The purpose of this standard is to calculate the sound exposure in the vicinity of existing or planned airfields and to supply the basis for later assessment. For this purpose, the calculation method described in this standard provides acoustic parameters for an arbitrary site in the vicinity of an airfield as a result.
It is not the purpose of this standard to specify assessment methods or to create specifications for the assessment of aircraft noise exposure at airfields.
In general, aircraft with a maximum take-off mass (MTOM) of up to 5 700 kg operate at airfields, however at certain airfields aircraft with a maximum take-off mass of up to 20 000 kg operate as well. For this reason, only the parameters of sound emissions of ultra-light aircraft, power gliders, propeller aircraft and jet aircraft with a maximum take-off mass of up to 20 000 kg, as well as helicopters with a maximum take-off mass of up to 10 000 kg, are contained in this standard.
In general, the sounds generated by taxiing aircraft, by hovering helicopters with hover out of ground effect and by the operation of auxiliary power units as well as sounds due to engine run up tests on the aircraft operation areas are neglectable compared with the noise of departing and approaching aircraft.
NOTE In individual cases, the calculation regulations for execution of the act for protection against aircraft noise (AzD and AzB) can be alternatively consulted for description of the sounds which are not considered here.
