Current through Register Vol. 42, No. 9, June 28, 2024
(1) Approach And Departure Paths For Public
					And Private-Use Airports. All airports are required to maintain approach and
					departure paths which are free of obstructions for the safe operation of
					aircraft during landings and take-offs. The approach and departure paths for
					public and private-use airports are defined as follows:
(a) For all hard surface runways the approach
					and departure path will begin 200 feet from the runway end (runway
					threshold).
(b) For all turf or sod
					runways the approach and departure path will begin at the marked threshold
					(runway end) for that runway.
(c)
					The approach and departure path for all public-use and private-use airport
					runways will be centered along the extended runway centerline and extend for
					1000 feet beyond the primary surface. Curved or "dog-legged" approaches with a
					total deflection of no more than fifteen degrees from runway centerline at a
					point 1,200 feet from the runway end are acceptable.
(d) Repealed
(e) Dimensions of approach and departure
					paths for private and public use airports:
INNER OUTER
APPROACH TYPE WIDTH WIDTH LENGTH ACREAGE
VISUAL 250 FEET 450 FEET 1000 FEET 8.04 ACRES
(f) The approach and departure path for all
					public or private-use runways will slope up at a ratio of 20:1.
(g) All penetrations of the approach and
					departure paths, whether natural or man made, constitute an obstruction to
					navigation and must be removed. If the obstruction is not removed the threshold
					must be placed at a point on the runway that will provide a clear and
					unobstructed flight path. This will be accomplished by displacing or relocating
					the threshold of the runway. The approach slope will begin from the point of
					displacement on runways with a displaced threshold, which will shorten
					available runway length for landings to that runway end.
(h) No later than January 1, 2005, the land
					area beneath the approach and departure path for all publicly owned runways
					must be controlled by the airport owner. Ownership of the property may be
					accomplished by purchase in fee simple or by written perpetual agreement with
					the owner of the land. Use of the land must be restricted to activities and
					uses that are compatible with the approach and departure of aircraft using the
					airport. After January 1, 2005, no license will be issued for any publicly
					owned airport that does not own, or control by legal contract, the area of land
					beneath the boundaries of the approach and departure path that is required for
					that particular site. Prior to January 1, 2005, this requirement must be met by
					any licensed publicly owned airport which extends an existing runway. Any
					runway extension that would place the approach and departure path over land not
					controlled or owned by the airport must relocate the runway end to meet the
					requirements of this chapter.
(i)
					Dimensions of approach and departure paths for private use airports: The
					approach and departure path for all private use airports shall meet the
					following requirements:
Inner Width: Shall conform to the width of the Primary
						Surface.
Outer Width: Shall be calculated based upon a flare ratio of
						10:1.
Length: 1000 feet.
