Environmental legislation and military aviation
• Environmental protection act and decree (2000) – Airfields are required to
acquire an environmental permit
• Exceptions for military aviation
– Exceptions in conditions for granting permission (noise)
– Temporary military aerodromes (highway strips)
– Environmental impact of airspace policing operations

Environmental Permits and military aviation
– Environmental Permit
applications for airfields are
prepared in co-operation with
Finavia corporation
• Finavia is the operator of 25
airfields in Finland including
fields used by military aviation
– Military and civil aviation
activities and environmental
impacts are described in same
application
• Noise reports etc.
– Authority:
• Regional State Administrative
Agencies (6)
Environmental Permit Process

Environmental Permits
• Permits have been granted to 6 of 7 main airfields used by FiAF
• Permit conditions in valid permits
– Noise abatement regulations for military aviation
• General demands of noise abatement
• Regulations for night time operations (22-07)
• Regulations limiting expanding of LDEN 55 dB noise area to new populated areas
• Obligation to maintain and publish a noise abatement plan (In-flight guides)
– Regulations enable arranging sufficient air defense exercises and night time training

Aircraft Noise Assessment
• Aircraft noise area calculations and measurements – In Co-operation with Finavia
Environmental team
– Noise reports attached to env. permit applications
– Measurements are required in some cases
• Noise values are presented mainly as LDEN dB – Day(07-19), Evening(19-22), Night(22-07)
equivalent noise level • Day + 0 dB
Evening + 5 dB Night + 10 dB
– Day / Night LAeq and LMax are also used

Noise management in daily flight ops.
• Planning of flight
operations
• Efficient use of airspace

and approach
• Continuous decent

Exposure to military
aviation noise
• ~ 10 000 inhabitants in
military aviation
LDEN 55 dB noise areas
in Finland (2011)
– Aviation total ~ 25 000
– Street, Road, Rail
~ 1 000 000

Land use planning
• Regional councils
– Regional land use plans
• “The goal of the Regional
Land Use Plan is to create
a pleasant region that
functions economically and
ecologically”
– Noise areas around airports
• Aim is not to construct new
dwellings or other noise
sensitive facilities in noise
areas
– Municipalities apply noise
areas to more detailed plans
