Airport IRVR system

Accurate monitoring of weather conditions through the use of Automated Weather Observing Systems (AWOS) is one of the most important aspects that ensure continued safe operations at airports. Systems Interface designs and delivers a range of meteorological solutions to meet this demanding aspect of ATM operations. Working with technology leaders in their field, Systems Interface works exclusively with high-calibre product providers to deliver tailored turn-key solutions for airport applications in the civil and military arenas. Meteorological solution elements include: AWOS (Automatic Weather Observation System) IRVR (Instrument Runway Visual Range) ATIS (Automatic Terminal Information System) UNDERSTANDING HOW METEOROLOGICAL SYSTEMS WORK AWOS Automated Weather Observing System (AWOS) is an airport weather system with complete configuration capabilities that offers continuous, real-time data and reports on airport weather conditions at the airport. These systems generally report at hourly intervals but also report special observations if weather conditions change rapidly and cross aviation operation thresholds. AWOS systems are generally managed by Airports or Air Navigation Service Providers. AWOS systems make weather data available in a number of ways, including: An audio message is produced by a computer and transmitted to aircraft in the vicinity of the airport via radio frequency. This is the sole mandated method of weather reporting for an AWOS, and the message is refreshed at least once per minute. AWOS communications may also be regularly distributed through ground data link in METAR format, typically once every 30 minutes.
