CHAPTER 3 FACILITY REQUIREMENTS to be used in the long-term. Average aircraft delay for long-range planning is negligible – well under one minute. Based on this analysis, the airfield has adequate capacity to handle operations on a long-term basis. Additional airfield planning, however, will explore the value of possibly adding acute-angle exit taxiways to the runway/taxiway system as more of a safety measure (to more rapidly get airplanes off the active runway). 2. Airfield Facility Requirements Airfield facility requirements were developed for each of the Airport’s following functional areas: Airfield Layout Design Standards Runway Length Runway Width Pavement Strength Taxiway System Airfield Safety Areas FAR Part 77 Surfaces Navigational Aids 2.1 Airfield Layout Since the 2000 MPU, the airfield has been reconfigured to a parallel runway system, giving EUG the airfield capacity to accommodate projected aircraft operational demand through 2026. 2.2 Design Standards Important factors in the design and planning of an airport include the role of the airport, as well as the operating requirements of the critical aircraft that use that facility. The FAA provides guidance for planning and design through FAA Advisory Circulars, which promote safety, economy, efficiency, and longevity of airport facilities. For planning and design purposes, it is necessary to establish design standards applicable to operations and development at EUG. FAA Advisory Circular 150/5300-13, Airport Design, gives direction on determining the Airport Reference Code (ARC). The ARC is a coding system used to relate airport design criteria to the operational and physical characteristics of aircraft intended to operate at the airport. The ARC has two components. The first component, depicted by a letter, represents the aircraft approach category, as defined by the aircraft approach speed. The second component, depicted by a Roman numeral, represents the airplane design group, as defined by the aircraft wingspan and tail height. Generally, aircraft approach speed relates primarily to runways and related facilities, while aircraft wingspan and tail height relate primarily to separation criteria involving runway, taxiways, and structures. 3-2 Eugene Airport Master Plan Update (February 2010)
