AIRPORT APPROACH SAFETY ZONE.
The land that underlies the approach surface, excluding the RPZ.
AIRPORT DEPENDENT USE OR ACTIVITY.
A use or activity directly servicing the airport, employees working on the airport property or air service patrons. Direct service businesses and uses include such uses as aircraft fueling stations, aircraft repair facilities, hangars, air charter services, taxiways, heliports and other similar uses.
AIRPORT HAZARD.
Any structure, vegetation or use of land which exceeds height limits established by the airport imaginary surfaces.
AIRPORT IMAGINARY SURFACES.
The restricted three dimensional land and air space which is defined by the approach surface, transitional surface, horizontal surface and conical surface and in which any object extending above or within these spaces is an obstruction. See OAR Chapter 660, Division 13 exhibits for dimensions and graphics specifically defining these surfaces.
AIRPORT RELATED USE OR ACTIVITY.
A use that is determined to be a use requiring a location at or adjacent to an airport to be economically viable. Economic viability can be measured by finding that the use would suffer an identifiable and measurable economic disadvantage if not so located. Measurements may include consideration of the following: percentage of business done with aircraft or air cargo; and dependence of staff, management, sales personnel, vendors or clientele on air transportation.
APPROACH SURFACE.
A surface longitudinally centered on the extended runway centerline and extending outward and upward from each end of the primary surface. See OAR Chapter 660, Division 13 exhibits for graphics specifically defining this surface.
BUILDING RESTRICTION LINE (BRL).
This area is intended to protect the runway from building encroachment.
CONICAL SURFACE.
A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to one for a horizontal distance of 4,000 feet. See OAR Chapter 660, Division 13 exhibits for dimensions and graphics specifically defining this surface.
FREIGHT.
Services and facilities at public use airports.
HORIZONTAL SURFACE.
A horizontal plane 150 feet above the established airport elevation, the perimeter of which is constructed by swinging arcs of specified radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by lines tangent to those arcs. See OAR Chapter 660, Division 13 exhibits for dimensions and graphics specifically defining this surface.
NOISE SENSITIVE AREAS.
Within 1,500 feet of an airport, or within established noise contour boundaries exceeding 55 DNL.
NONPRECISION INSTRUMENT RUNWAY.
A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in nonprecision instrument approach procedure has been approved, or planned, or indicated on an FAA or state planning document or military service airport planning document.
OBJECT FREE AREA (OFA).
Two dimensional surface intended to be free of ground objects.
PLACE OF PUBLIC ASSEMBLY.
Structure or place which the public may enter for such purposes as deliberation, education, worship, shopping, entertainment, amusement, awaiting transportation or similar activity.
PRECISION INSTRUMENT RUNWAY.
A runway having an existing instrument approach procedure utilizing an Instrument Landing System (ILS), Microwave Landing System (MLS), Global Positioning System (GPS) or a Precision Approach Radar System (PAR). It also means a runway for which a precision approach system is planned and is not indicated by an FAA approved Airport Layout Plan, any other FAA or state planning document, or military service airport planning document.
PRIMARY SURFACE.
A surface longitudinally centered on a runway. See OAR Chapter 660, Division 13 exhibits for dimensions and graphics specifically defining this surface.
RUNWAY PROTECTION ZONE (RPZ).
An area off the runway end (formerly the clear zone) used to enhance the protection of people and property on the ground. The RPZ is trapezoidal in shape and centered above the extended runway centerline. It begins 200 feet beyond the end of the arcs usable for takeoff or landing. The RPZ dimensions are functions of the type of aircraft and operations to be conducted on the runway.
RUNWAY SAFETY AREA (RSA).
A defined surface surrounding the runway prepared or suitable for reducing the risk of damage to airplanes in the event of an undershoot, overshoot, or excursion from the runway.
TRANSITIONAL SURFACE.
Those surfaces which extend upward and outward at 90 degree angles to the runway centerline and the runway centerline. See OAR Chapter 660, Division 13 exhibits for dimensions and graphics specifically defining this surface.
UTILITY RUNWAY.
A runway that is constructed for and intended to be used by propeller driven aircraft of 12,500 pounds maximum gross weight or less.
VISUAL RUNWAY.
A runway that is intended solely for the operation of aircraft using visual approach procedures where no instrument approach procedures have been approved or planned or indicated on an FAA or state planning document or military service airport planning document.
