Aircraft.Includes airplanes, helicopters, and unmanned aerial vehicles (UAV), but not hot air balloons or ultralights.
Airport Sponsor.The owner, manager, person or entity designated to represent the interests of an airport.
Approach Surfaces.A surface longitudinally centered on the extended runway centerline and extending outward and upward from each end of the primary surface. The Federal Aviation Administration establishes and can potentially amend the following standards. The Approach Surfaces are described:
Airport Imaginary Surfaces.Those imaginary areas in space which are defined by the approach surface, transitional surface, horizontal surface, and conical surface.
Conical Surface.A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to 1 for a horizontal distance of 4,000 feet.
Horizontal Surface.A horizontal plane 150 feet above the established airport elevation, the perimeter of which is constructed by swinging arcs of 5,000 feet from the center of each end of the primary surface of each visual or utility runway and 10,000 feet from the center of each end of the primary surface of all other runways and connecting the adjacent arcs by lines tangent to those arcs.
Noise Sensitive Areas.Within 1,500 feet of an airport or within established noise contour boundaries exceeding 65 Ldn.
Primary Surface.A surface longitudinally centered on a runway. The primary surface extends 200 feet beyond each end of that runway. The width of the primary surface is 500 feet for Runway 31-13, and 1,000 feet for Runway 8-26.
Sponsor.The owner, manager, other person, or entity designated to represent the interests of an airport [OAR
660-013-0020(6)].
Transitional Surface.These surfaces extend seven feet outward for each one foot upward (7:1) beginning on each side of the primary surface which point is the same elevation as the runway surface, and from the sides of the approach surfaces thence extending upward to a height of 150 feet above the airport elevation (horizontal surface).
