Act 259 of 1959
259.482c Width of approach surface; outward and upward extension of approach surface.
Sec. 2c.
(1) Based upon the most precise approach available or planned for the end of a runway, the width of the approach surface at the end of the primary surface equals the width of the primary surface and expands uniformly to the following maximum width:
(a) For the end of a utility runway, which end has only a visual approach procedure.................. 1,200 feet (b) For the end of other than a utility runway, which end has only a visual approach procedure........ 1,500 feet (c) For the end of a utility runway, which end has a nonprecision instrument approach procedure...... 2,000 feet (d) For the end of other than a utility runway, which end has a nonprecision instrument approach procedure and a visibility minimum established by the FAA that is greater than 3/4 of a statute mile........ 3,500 feet (e) For the end of other than a utility runway, which end has a nonprecision instrument approach procedure and a visibility minimum established by the FAA that is 3/4 of a statute mile or less............. 4,000 feet (f) For the end of a runway, which end has a precision approach procedure.......................... 16,000 feet(2) Based upon the most precise approach available or planned for the end of a runway, the approach surface extends outward and upward at the following slope for the following distance:
(a) For the end of a utility runway regardless of the available or planned approach, or for the end of other than a utility runway which end has only a visual approach procedure, a slope of 20 to 1 for 5,000 feet from the end of the primary surface.
(b) For the end of other than a utility runway, which end has a nonprecision instrument approach procedure, a slope of 34 to 1 for 10,000 feet from the end of the primary surface.
(c) For the end of other than a utility runway, which end has a precision instrument approach procedure, a slope of 50 to 1 for 10,000 feet from the end of the primary surface and, from that point, a slope of 40 to 1 for an additional 40,000 feet.
