The recent rise in the number of flights by jet aircraft due to a sharp
rise in the demand of air transport has given rise to the problem of aircraft
noise in the area adjacent to an airport. The situation is so stringent that
there is no alternative but to change the anti-noise projects initially incorporated
in the Second Five-Year Airport Improvement Program. Particularly in the area
around Osaka International Airport, aircraft noise has taken on the character
of a serious social issue in the last several years. Civil movements have been
launched for the removal of the airport and lawsuits filed for a suspension
of the night flits and a compensation for the damage inflicted upon this area.
(Table lll-8)
To cope with aircraft noise at the source of its origin, measures are being
implemented to assign new types of aircraft featuring a greater transport capacity
but consideraly lower noise than the currently assigned planes and to impose
more powerful restrictions on the departure and arrival of aircraft. The attempts
to abate noise by improving aircraft operation systems are also being stepped
up on an international scale, and studies are being conducted on steep climbing
and two-step approach.
In some areas, there remains one problem or another yet to be solved even
after measures have been implemented for the source of aircraft noise and the
structure of the airport has been improved. For these districts, the measures
to work for a rationalization of land utilization and positively harmonize an
airport with its periphery as well as the compensations for the moval of dwellings
from this area and the anti-noise construction projects are being taken into
consideration. To implement these measures, the Aircraft Noise Prevention Law
has been put into effect.
Compensations for the moval of dwellings and other facilities and financial
aids for the construction of noise abating facilities at schools, hospitals
and other public buildings have already been provided for Osaka International
Airport and eight other airports designated as "special airports" by this law.
With respect to the measures for a rationalization of land utilization,
an airport periphery redevelopment program has been formulated for Osaka Inter
national Airport as it has been designated by this law as an airport the environment
of which calls for redevelopment. Under this program, an Osaka Airport Periphery
Redevelopment Organization has been established and is now engaged in the development
of green buffer zones around the airport, renewal projects designed to place
facilities outside these zones which may coexist with aircraft noise, and other
necessary projects.
