The Aviation Standard WindObserver has been accepted for service by both the FAA Federal Aviation Administration (USA) and the CAA Civil Aviation Authority (UK) for the observation and reporting of surface wind. This WindObserver meets the requirements of Annex 3 to the Convention on International Civil Aviation (ICAO) when supplied as part of a suitable Automated Weather Observing System (AWOS).

This variant of the WindObserver has been designed to remain ice free in most freezing weather conditions. With exceptionally high heating power the instrument is ideal for use in extreme conditions where performance and high reliability are paramount.

With 150 Watts of electrical heating producing 1 Watt/cm² and tested in accordance with MILSTD810F, the unit is particularly suited to operate as part of Aviation Automatic Weather Observing Systems which are often exposed to extreme weather conditions. Manufactured from stainless steel with no moving parts, the WindObserver is ideal for replacing mechanical anemometers, which require regular maintenance and calibration.
