AIRPORT MASTER PLAN <br />W EATHER R EPORTING <br />The San Marcos Regional Airport has an Automated Weather Observation System <br />(AWOS) - 3 that is the primary source of wind direction, velocity, and altimeter data <br />for weather observation purposes at the Airport. The AWOS-3 is an automated <br />sensor suite that reports weather conditions over a discrete radio frequency for <br />pilots to receive real-time weather information. The <br />AWOS-3 information can be received by calling 512-353-8005 or obtained from the <br />), which is broadcast on <br />120.825 MHz. However, the ATIS system has had a history of outages. When an <br />outage occurs current weather information is not available via the ATIS frequency. <br />The AWOS-3 is co-located with the glide slope at the approach end of Runway 13. <br />The AWOS-3 is owned and maintained by the FAA. It is in good condition. <br />W IND AND T RAFFIC I NDICATORS <br />While automated weather analysis and reporting systems such as an AWOS are a <br />tremendous asset to an airport, it is important that pilots are provided with a visual <br />indication of wind speed and direction while operating at an airport. For this <br />purpose, airports are typically equipped with one or more wind direction indicators. <br />The most common type of wind indicator used at airports are windsocks because <br />they are relatively easy to install and maintain. The San Marcos Regional Airport is <br />equipped with one primary windsock and four supplemental windsocks. <br />The primary windsock is located approximately 385 feet north of the Runway 8/26 <br />centerline and approximately 2,150 feet east of the threshold of Runway 8. The <br />windsock is lighted for nighttime operations and is equipped with a segmented <br />circle. There are no landing strip indicators or traffic pattern indicators associated <br />with the segmented circle. The primary windsock and segmented circle are in good <br />condition. The location of the four supplemental windsocks are: <br /> Supplemental Windsock #1 Located close to the approach end of Runway <br />13, approximately 380 feet southwest of the Runway 13/31 centerline and <br />925 feet from the Runway 13 threshold. <br /> Supplemental Windsock #2 Located southeast of the intersection of <br />Runway 8/26 and Runway 13/31. Approximately 410 fee <br />respective centerline. <br />Inventory Chapter Page 23 of 52 <br />October 2020 <br /> <br />
