How to Achieve Full CAR120-Compliance for Your AWOS?

Save time with Vaisala´s certificate and make your airport immediately CAR120 compliant and become quickly operational.

What is CAR120?

In Australia the Civil Aviation Safety Authority, CASA, is responsible for the regulation of civil aviation. CASA regards the safety of air navigation as the most important consideration. Therefore CASA places strict responsibilities on airport operators with regard to their automated weather reporting – through the CAR120 regulation, Civil Aviation Regulation Part 120.

In practice this means that any Automated Airport Weather Observation System, AWOS, must be CAR120-compliant. If the AWOS is not CAR120-compliant the data cannot be used for aviation purposes.

What are the requirements to become fully CAR120-compliant?

There are four areas that you need to evaluate and be in compliance with, when providing weather data for aviation purposes. Vaisala AviMet® AWOS meets all of the requirements and full CAR120 compliance is ensured from day one:

AviMet® Automated Weather Observing System AWOS

Vaisala AviMet® AWOS is a fully configurable, modular system that fulfills the needs of both large and small airports. It is compliant with ICAO and CAR120 regulations. A typical AWOS installation comprises sensors located along the runway, one or two central data unit (CDU) computers, and user workstations.

  • Runway sensors measure variables such as wind speed and direction, precipitation, visibility, present weather, cloud layer/ceiling, and runway visual range (RVR)
  • A central data unit computer for data collection, meteorological calculations, ICAO report generation, system diagnostics, and data storage
  • Workstations for providing observers, forecasters, and other airport staff with system access
