In addition to the foregoing, there are established height limits sloping seven (7) feet outward for each foot upward beginning at the sides of and at the same elevation as the approach surface, and extending to where they intersect at the conical surface.
C. Horizontal zone. A horizontal zone is established at one hundred fifty (150) feet above the airport elevation.
D. Conical zone. A conical zone slopes twenty (20) feet outward for each foot upward beginning at the periphery of the horizontal zone and at one hundred fifty (150) feet above the airport elevation and extending to a height of three hundred fifty (350) feet above the airport elevation.
