(1)

Airport approach surface zones. There shall be four (4) approach zones, one (1) at each end of each runway, which approach zones are defined as follows: Beginning at a point two hundred (200) feet from the ends of the runways and starting at elevations as follows: North end north-south, two hundred eighty (280) feet MSL; south end north-south two hundred seventy-eight (278) feet MSL; west end east-west, two hundred seventy-five (275) feet MSL and east end east-west, two hundred eighty-five (285) feet MSL. Starting width of two hundred fifty (250) feet at a point two hundred (200) feet from the ends of the runways and extending outward for a distance of ten thousand (10,000) feet, each with widths of two thousand two hundred fifty (2,250) feet at the limits, the zones being symmetrical about the center lines of the runways extended.

(2)

Transition surface zones. There shall be eight (8) transition surface zones, one on each side of each approach zone, which transition surface zones are defined as follows: An inclined surface at right angles to the runway center line and/or the project[ion] thereof extending on a slope of 7:1 from the edge of the landing zone at elevation two hundred eighty (280) MSL to an intersection with the horizontal surface at elevation four hundred thirty (430) feet MSL and extending on a slope of 7:1 from the edge of approach surfaces to an intersection with the horizontal or conical surfaces.

(3)

Horizontal surface zones. There shall be four (4) horizontal surface zones defined as follows: A horizontal circular surface at elevation four hundred thirty (430) feet MSL centered at the established airport reference point with a radius of five thousand (5,000) feet.

(4)

Conical surface zones. There shall be four (4) conical surface zones defined as follows: An inclined conical surface concentric with and adjacent to the perimeter of the horizontal surface with a horizontal width of three thousand (3,000) feet and a 20:1 slope from elevation four hundred thirty (430) feet MSL at the circumference of the horizontal surface to elevation five hundred eighty (580) feet MSL at the exterior circumference of the conical surface.

(5)

Landing zones. The width of the landing zones shall be two hundred fifty (250) feet.
