CHAPTER 3 FACILITY REQUIREMENTS EUG continually works to meet the standards and maintain the requirements of these surfaces, reviewing criteria and compliance as part of annual FAA inspections. Airport improvement projects are designed and implemented to the most current standards. 2.8 FAR Part 77 Surfaces Federal Aviation Regulation (FAR) Part 77, Objects Affecting Navigable Airspace, establishes airspace around an airport, and the standards for determining objects as hazards to air navigation, termed “obstructions”. Potential obstructions include terrain and natural growth features, towers, structures, and construction equipment (permanent or temporary). Under FAR Part 77, an aeronautical study can be undertaken by the FAA to determine if an object is a hazard to air navigation. However, there is no authorization permitting the FAA to limit object heights, or determine which objects should be lighted or marked. In an aeronautical study determination, the FAA acknowledges that state or local officials have control over the appropriate use of property beneath an airport’s airspace. Airspace around an airport is defined by several imaginary surfaces, as defined in FAR Part 77. As these imaginary surfaces are intersecting and inter-related, the most restrictive surface controls the permissible height of an object underneath multiple surfaces. These FAR Part 77 surfaces are identified and evaluated on the Airport Layout Plan. There are no FAR Part 77 obstructions. EUG continually works to meet the standards and maintain the requirements of these surfaces. Airport improvement projects are designed and implemented to the most current standards. 2.9 Navigational Aids (NAVAIDs) NAVAIDs provide guidance to pilots and aircraft during flight planning and operation. The type, mission, and volume of aeronautical activity, in association with airspace, meteorological conditions, and capacity data, determine the need and eligibility for NAVAIDs.NAVAID requirements are based on recommendations contained in FAA Handbook 7031.2, Airway Planning Standard Number One, and FAA Advisory Circular 150/5300-13, Airport Design. Three categories of NAVAIDs are discussed in the following sections. Terminal Area NAVAIDs Terminal area NAVAIDs provide control to aircraft to maintain an orderly flow of air traffic, prevent aircraft incursion, and support maneuvering. EUG’s terminal area NAVAIDs include the Airport Traffic Control Tower (ATCT), Cascade Terminal Radar Approach Control (TRACON), Cascade Air Route Traffic Control Center (ARTCC), and Airport Surveillance Radar (ASR). These facilities are owned and operated by the FAA, and operate in the FAA office, located near the passenger terminal. The ASR is located west of Runway 16R/34L. The ATCT controls aircraft on and in the vicinity of the airfield, the TRACON controls arrivals and departures, and the ARTCC provides enroute control. Pilot communication and control is transferred among these facilities during the different phases of flight. The ASR scans 360 degrees to identify air 3-6 Eugene Airport Master Plan Update (February 2010)
