, �~?/�- port, servingmviatiun other than commercial airlines. The facilities include any runway, land urea, or other structures designed or used for landing, or taking off of small aircraft, A basic utility aircraft /-sic/ which is equivalent to the Midway pro- posal would accommodate about-9S%-of the propeller airplanes that weigh under 12,600 pounds. Mr. Cannity defined several terms which dealt with the physical layout of the airport and the air surfaces surrounding it: 1) Primary Surface--Is the actual runway itself A surface longitudin- ally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends 200 feet beyond each end of that run- way. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline. The width of a primary surface for a basic utility airport is 250 feet for runways having only visual approaches. 2) Approach Surface--A surface longitudinally centered on the extended runway entarline and extending outward and upward from each end of the primary surface. An approach surface is applied to each end of each run- way based upon the type of approach available or planned for that runway end. The inner edge of the approach surface is the same width as the primary surface and expands uniformly to a width of 2,000 feet for that end of a utility runway with a nonprocisinn instrument upproach. The approach surface extends for a horizontal distance of 6,000 feet at a slope of 20 to 1 for all utility and visual runways. The runway clear zone is an area at ground level that begins at each end of the primary surface and extends with the width of the approach surface to terminate directly where the slope reaches a height of 60 feet above the runway end -or 50 feet above the terrain. = , Mr. Cannity continued his presentation to the Boards by quoting from a letter written by Mr. Bruce Matthews, of the North Carolina Department of Trans- portation, Division of Aviation, on June 30, 1982, to Planning Director Jim Polatty.
