FACILITY REQUIREMENTS <br />Annual Service Volume <br />Annual service volume (ASV) is the estimated capacity of the runway configuration in terms of annual <br />operations. This is used as a general measure of total throughput for future planning of the airfield. <br />Table 3-4 compares forecast operations to the existing airfield annual service volume. The ASV of Eugene <br />Airport is 320,000 operations. <br /> <br />Comparing the forecasted operations to the ASV creates an ASV ratio which helps identify any existing <br />and future capacity constraints. The generally accepted industry benchmark to begin planning for <br />additional airfield capacity is when demand reaches 60 percent of the ASV. The ASV ratio for Eugene <br />Airport only reaches 22 percent by Planning Activity Level 3. With aircraft operations being forecasted to <br />remain below 70,000 annual operations and total throughput of the airfield system estimated at 320,000 <br />operations per year, airfield capacity will remain adequate well beyond the 20 year planning horizon. <br /> <br />TABLE 3-4 <br />COMPARISON OF FORECAST OPERATIONS AND ANNUAL AIRFIELD CAPACITY <br />ExistingPlanning Activity Level <br />2015PAL 1PAL 2PAL 3 <br />60,21461,77364,49369,763 <br />Forecast Operations <br />320,000320,000320,000320,000 <br />Existing ASV <br />19%19%20%22% <br />ASV Ratio <br />Sources: RS&H Forecast Demand, FAA AC 150/5060-5 Airport Capacity and Delay, <br />FAA Airport Design for Microcomputers, RS&H Analysis, 2016 <br />AIRFIELD FACILITY REQUIREMENTS <br />This section analyzes the various elements of the airfield and their ability to accommodate forecast <br />demand. <br />Airfield Configuration <br />As shown in Chapter 1, Inventory of Existing Conditions, Eugene Airport has two parallel runways (16R- <br />34L and 16L-34R) separated by 4,300 feet from centerline to centerline. These runways are served by <br />inward parallel taxiways and a mix of FAA standard taxiway connectors and non-standard taxiway <br />connectors which are remnant pieces of previously existing runways and taxiways used during prior <br />airfield layouts. The two parallel taxiways are also connected via an east-west oriented taxiway. The airfield <br />taxiways, taxiway connectors, and apron configurations will be one of the primary focuses of this facility <br />requirements chapter and the overall master plan. These airfield components will be discussed further in <br />future sections of this chapter. <br />Airport Design Criteria <br />Each airport has a design aircraft, which is the largest aircraft that regularly uses the airfield. The airfield <br />must be designed so that the most demanding, regularly operating aircraft is able to use the runways, <br />taxiways and ramps. Airport design standards are established in FAA Advisory Circular 150/5300-13A <br />EUGENE AIRPORT MASTER PLAN 3-7 <br /> <br />
