FORECASTS OF AVIATION DEMAND CHAPTER 2 <br />3. Aircraft Operations <br />Aircraft operations are the activity of moving aircraft in the EUG vicinity, including departing and arriving <br />aircraft. Observed operations data is provided to Airport management by EUG’s airport traffic control <br />tower (ATCT), which maintains data as it communicates and controls aircraft in EUG’s vicinity. <br />Operations are categorized into commercial service, general aviation (GA), and military. Commercial <br />service includes commercial passenger and cargo. Operations are also categorized into local and <br />itinerant. Local operations are performed in local traffic patterns within site of the Airport, or in local <br />practice areas within 20 miles of the Airport. Itinerant operations are non-local. Commercial carrier <br />operations are itinerant. Military operations are 59 percent itinerant, and 41 percent local (although none <br />are based at the airport). GA operations are 54 percent itinerant, and 46 percent local. There is no <br />expected change in itinerant vs. local operations at EUG, and therefore these averages will be maintained <br />for forecasting. <br />3.1 Aircraft Operations History <br />Table 2-6 <br /> shows historical aircraft operations. There were 112,643 operations at EUG in 1997, which fell <br />to 92,779 in 2006. Commercial operations, averaging 28 percent of total EUG operations, fell from <br />28,256 in 1997 to 24,777 in 2006. GA operations, averaging 70 percent of total EUG operations, fell from <br />81,722 in 1997 to 66,185 in 2006. Military operations, averaging 2 percent of total EUG operations have <br />varied over the past 10 years from a low of 989 to a high of 2,665. <br />Table 2-6: Historical Aircraft Operations <br />YearCommercial GAMilitary Total <br />1997 28,256 81,722 2,665 112,643 <br />1998 28,361 78,052 1,995 108,408 <br />1999 29,379 82,017 1,944 113,340 <br />2000 32,602 75,632 2,263 110,497 <br />2001 30,836 70,138 2,445 103,419 <br />2002 24,500 68,620 993 94,113 <br />2003 26,373 63,340 989 90,702 <br />2004 28,166 62,626 1,001 91,793 <br />2005 26,225 61,096 1,704 89,025 <br />2006 24,777 66,185 1,817 92,779 <br />CAGR <br />1997-2006 -1.45% -2.32% -4.17% -2.13% <br />Source: Airport management records <br />2-8 <br />Eugene Airport Master Plan Update <br />(February 2010) <br /> <br />
