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 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

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
