The datum for measurement of such heights, except a as otherwise specified shall be the elevation, based on the i I U.S.G.S. datum of the airport reference point (A.R.P.), which is given the established airport elevation. i b. The height limit for each type of zone ils� hereby established as follows: i ; (1) PRIMARY ZONE: A surface longitudinally centered on a runway and extending on either side of any beyond each end of, a runway. The elevation of any point on the longitudinal Iprofi16 of a primary zone, including the extensions, coincides with the elevation of the centerline of the runway, or extension, as appropriate. (2) APPROACH ZONES (ILS) : A surface longitudinally ! centered on the extended centerline of an ILS runway, beginning (at the end of the primary zone and extending outward and upward at a slope of 50 to 1 for a horizontal distance of 10,000 feet I ,and at a slope of 40 to 1 for an additional 40,000 feet. This i surface is the width of the primary zone at the beginning and 1 ;expands uniformly to a width of 16,000 feet at a distance of i 150,000 feet from the end of the primary zone. i (3) APPROACH ZONES (Non -ILS): A surface longitudinally centered on the extended centerline of the runway, beginning at the end of the primary zone with slopes and dimensions as follows: i (a) Airports constructed to "VFR Airports" standards I i surface begins 200 feet wide at the end of the primary zone and i extends outward and upward at a slope of 20 to 1, expanding to i !a width of 500 feet at a horizontal distance of 3,000 feet.
