The Vaisala US AWOS generates real time weather reports every minute. AWOS weather reports are made available to airport personnel via displays on operator terminals, and to pilots via high quality, digitized voice transmissions using a VHF frequency or voice-capable NAVAID. AWOS reports are also available by telephone for flight planning and can be sent to the FAA’s Weather Network for flight planning purposes.

The Vaisala AWOS is FAA-certified for us in non-federally owned airports, and provides weather information for FAR Part 91, Part 135 and Part 121 operators. It is also eligible for Airport Improvement Program (AIP) funding.

Vaisala AWOS systems and solutions are designed to grow with your airport, making them the smart choice for long-term investment. All of the systems are scalable, with an open system architecture that makes upgrading and expansion easy. DBT Transportation Services offers the best resources and capabilities for tailoring a complete solution to any weather-related challenge. Vaisala AWOS systems can be customized to incorporate sensors that detect thunderstorms as well as other problematic weather phenomena such as freezing rain.

DBT can assist in all aspects of your AWOS project – from initial planning through maintenance and lifecycle support. We offer flexible configurations to meet the requirements of your airport and to minimize the installation costs.
