METHOD FOR ESTABLISHING THE SEVENTH SUBZONE OF THE AERODROME AREA

The existing regulatory and methodical base does not provide for establishing airport zones (AZs). There are no unified approaches
to establishing relevant boundaries, control over them, and substantiating limitations on use of land spots.
The developed procedure for establishing the sanitary (seventh) subzone in an AZ creates a universal algorithm for determining
boundaries of this subzone in any AZ. Methodical approaches contain requirements to creating boundaries of the sanitary (seventh)
subzone including relevant computations, computed boundaries being verified with instrumental observations (measurements), zoning
the sanitary (seventh) subzone as per health risk criteria, and subsequent production control. Airports used in civil aviation have
been differentiated for the first time within the procedure; it was done in order to separate requirements to accomplishing both verifying
measurements and production control. Besides, approaches to zoning the sanitary (seventh) subzone in an AZ as per health risk
criteria have been implemented for the first time; these criteria are applied to determine limitations on use of land spots. Averaged
daily noise level (LAd) was used as a noise exposure indictor. Four zones with different risk levels were determined with different types
of economic activities to be performed in them depending on functions of capital construction objects located there.
