FACILITY REQUIREMENTS <br />3.5.5.1Visual Aids <br />Visual aids at EUG include those specific to each runway and those that serve the whole airport. <br />Table 3-17 lists the visual aids at EUG. Analysis determined the Airport is equipped with all the required <br />and recommended visual aids. Some systems are dated and consideration for upgrades are necessary <br />within the planning period. This includes the Runway 34L VASI, which is in adequate condition today but <br />is a dated system. When the VASI system is targeted for replacement in the future, it is recommended that <br />a PAPI system be installed in its place. Light emitting diode (LED) PAPI units are currently being <br />9 <br />researched by the FAA for use at airports. <br /> LED PAPI units would reduce the time needed for warm up to <br />10 <br />service the PAPI resulting directly in decreased energy use, and indirectly reducing greenhouse gas <br />emissions. <br /> <br />The Airport’s rotating beacon is reaching the end of its useful life and a new beacon is recommended <br />within the planning period. A new location is recommended within a more secured and remote area. <br />Additionally, the Airport’s segmented circle is not adequate for an airport that serves air carrier operations <br />when the control tower is closed. To adhere to CFR 14 Part 139.323(b), the airport requires a landing strip <br />indicator and a traffic pattern indicator. With a parallel runway configuration, these elements also help to <br />denote the typical traffic pattern for each runway. <br /> <br />TABLE 3-17 <br />AIRPORT VISUAL NAVIGATIONAL AIDS <br />Primary RunwayParallel Runway <br />Adaquate () or <br />Description <br />Deficient (X) <br />16R34L16L34R <br />Visual Aids <br />Lighting SystemHIRLHIRLHIRLHIRL <br />Approach LightingALSF-IIODALSMALSRREIL <br />Touchdown Zone Lightingyesnonono <br />Visual Slope IndicatorPAPIVASIPAPIPAPI <br />Runway MarkingsPrecision Precision PrecisionPrecision <br />RWY Centerline Lightsyesyesnono <br />Runway Windconeyesyesyesyes <br />Segmented Circle----X <br />Rotating Beacon----X <br />Source: FAA Chart Supplements, FAA.gov, RS&H Analysis, 2016 <br />Notes: ALSF-II = High intensity approach light system with sequenced flashers, MALSR = Medium intensity approach light system <br />with runway alignment indicator lights, ODALS = Omnidirectional approach light system, PAPI = Precision approach path <br />indicator, VASI = Visual approach slope indicator, REIL = Runway end identifier lights, RVR = Runway visual range is used for <br />determining airfield visibility for all precision approaches. <br /> <br />9 <br />Federal Aviation Administration, Lighting Systems – Precision Approach Path Indicators (PAPI).
