FAA Certified AWOS

Mesotech supplies FAA certified AWOS for any size airport.
We apply our extensive experience designing, building, and installing systems for the US Air Force to deliver the highest quality AWOS on the market.

  • Our Airport Weather Advisor® systems and software have been in active development and use since 1993.
  • Our systems are fully certified - none of our sensors are "advisory only"
  • We provide training for local airport or third party maintainers to reduce ongoing maintenance costs
  • Our phones are staffed by engineers - we are happy to answer questions whether you're in the market for a system or not. Give us a call!

Airport Improvement Funding and AWOS

Federal funding is available to help airports install FAA certified AWOS. Learn more about what funds are available and how to get them.

Benefits of Choosing an FAA Certified AWOS

Choosing a certified system regulated by the FAA is an assurance of quality, safety, and value for your airport. Learn about AWOS alternatives and the benefits of a certified AWOS.

Cost and Funding Options for AWOS

The price of AWOS systems varies significantly. Learn more about the cost of AWOS systems and how purchases can be funded.

THE ROLE OF AWOS

Understanding the weather is paramount for all airports to help ensure the safety of their passengers, personnel, and cargo. An Automated Weather Observing System (AWOS) plays a crucial role in that understanding. AWOS measure a variety of meteorological parameters and process the data using special algorithms to automatically create official observations (METARs). The METARs and one minute observations are broadcast to aviation personnel to keep them advised of current weather conditions.

 

In the United States, all AWOS systems sold must be certified by the Federal Aviation Administration (FAA) for use in the National Airspace System (NAS).

 

There are only three companies that supply FAA approved systems. You can find the official list from the FAA at this link.

 

Regular maintenance is required three times per year by a technician who has received verification authority by the FAA. The technician needs FCC licensure (GROL), training on the system, and must pass a hands-on exam.

 

Aviation AWOS systems are available at a range of levels to accommodate your airport’s requirements and meet both your budget and your needs. An AWOS III or higher is required to disseminate data to the flying community via NADIN/WMSCR.

AWOS LEVELS

Mesotech's FAA Certified Airport Weather Advisor® systems are available in the AWOS capability levels defined by the FAA. Each Airport Weather Advisor® system has a set of common components for data collection and processing and the AWOS level defines what sensing and reporting capabilities it has. Most airports opt for one of the AWOS III levels.

AWOS A: Altimeter settings

AWOS A/V: Altimeter setting and visibility

AWOS I: Wind speed and direction, temperature, dew point, altimeter setting, and density altitude

AWOS II: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, and visibility

AWOS III: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, and sky condition

AWOS IIIP: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, sky condition, and present weather

AWOS IIIPT: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, sky condition, present weather, and thunderstorm/lightning

AWOS IV Z: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, sky condition, present weather, thunderstorm/lightning, and freezing rain

FAA AWOS Specifications


The requirements for FAA certified AWOS systems are fully specified by FAA Advisory Circular No. 150/5220-16.

To facilitate fair and open competition in the non-Federal AWOS market, we have put together a set of sample specifications that are based solely on the advisory circular and are not vendor specific.
