The OSI AWOS AV™ system is a fully automated aviation weather observing and reporting system designed to support airborne and ground users. This FAA-certfied AWOS is equipped with dual-pressure sensors and visibility sensors for determining official altimeter settings, visibility, and reporting via FCC-licensed UHF data radio, Internet, land line or cell phones.
A basic OSI AWOS AV™ system consists of:
