Take-offs with jet planes, which are noise certified
according to ICAO Annex 16 Chapter 2 must after the first of April
1999 not take place between 2300-0600 (local time), with the exception
of delayed flights with scheduled time departure at between 0600-2300.
Any exceedings of the stated level caused by safety precautions,
vital flights or meteorological conditions which have influence
on the sound diffusion will not be regarded as a violation of
the term.
The maximum A-weighted sound pressure level (Lamax) from take-offs
and landings must not exceed 80 dB(A) between 2300-0600 (local
time), as shown in the 80 dB curve in Appendix
1 with the exception of delayed flights or aircraft arriving
before time but scheduled for departure or arrival between 0600-2300.
Any exceedings of the stated level caused by safety precautions,
vital flights or meteorological conditions which have influence
on the sound diffusion will not be regarded as a violation of
the term.
From the first of January 2000, the maximum A-weighted sound
pressure level (Lamax) during take-offs and landings between 2300-0600
(local time) must not exceed 80 dB(A) in the residential areas
within the town limit - with the exception of the areas in the
northern part of Billund, but delayed flights or aircraft arriving
before time with scheduled time of departure or arrival between
0600-2300 are excepted from this rule.
Any exceedings of the stated level caused by safety precautions,
vital flights or meteorological conditions which have influence
on the sound diffusion will not be regarded as a violation of
the term.
The airport must carry out an examination of how to reduce the
A-weighted sound] pressure level (Lamax) in order to meet the
demand.
ICAO (International Civil Aviation Organization) Annex 16, Vol.
I, Chapter 2 and 3 concerning noise certification of subsonic
jet planes.
After the first of July 2007, the maximum A-weighted sound pressure
level (Lamax) from take-offs and landings between 2300-0600 (local
time) must not exceed 80 dB(A) according to the 80 dB curve shown
in Appendix 1, with the exception
of the areas in the northern part of Billund, but delayed flights
or aircraft arriving before time with scheduled time of departure
or arrival between 0600-2300 are excepted from this rule.
Any exceedings of the stated level caused by safety precautions,
vital flights or meteorological conditions which have influence
on the sound diffusion will not be regarded as a violation of
the term.
Noise from aircraft during take-off and landing
On the first of April 2007, the airport has to send in noise calculations
measured by the TDENL method for year 2006, as well as the future
noise exposure.
The calculations have to be done as described in the National
Agency of Environmental Protection guide No. 5/1994: "Noise
from Airports". The calculation has to be done by a laboratory
approved by the National Agency of Environmental Protection to
carry out "environmental measurement - external noise".
Hereafter, this calculation should be repeated every seventh
year.
The calculations have to cover one calendar year and must be
done on the basis of number of operations during the 3 months
when the noise exposure is at its worst.
The calculations of the annual values as well as the monthly
are to be sent to the supervising authority no later than the
first of February each year.
Each calculation has to include the number of operations dispersed
on the type of aircraft, time of day/week and lane distribution.
The establishment of at least 1 permanent measuring stations
and 1 mobile measuring station in the environment is necessary
to check that the maximum value of noise from aircraft at night
does not exceed the fixed demands of the noise value.
The number of take-offs with Chapter 2 aircraft or similar noisy
aircraft type (MD80) between 2300-0600 as well as the reason for
the take-off should be registered in a journal. |
