Michigan Compiled Laws § 259.482c Width Of Approach Surface; Outward And Upward Extension Of Approach Surface.


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.
