Automatic AWOS System

The CND AWOS (Automatic Weather Observation System) utilizes the features of the Vaisala WXT520 Weather Transmitter to provide a low cost and low maintenance Airport weather reporting system. The WXT520 provides Wind Direction, Wind Speed, Temperature, Pressure, Humidity, Rain and Hail readings from a single integrated unit and is connected to the CND ATIS Servers up to 2000 feet away via RS422 serial cable. The system is supplied with a 10 Meter Stainless Steel self supporting mast and lightning rod.

The CND ATIS display provides full support for the WXT520 output and reports the following:

2 Min Average Wind Speed and Direction updated each minute
Instantaneous Wind Speed and Direction 1 updated each second
1, 2, 5 or 10 minute average wind speed and direction readings by operator selection
Temperature Humidity and Dewpoint each minute
QNH, QFF and Density Altitude each minute
Rainfall in past hour

Data from the WXT520 is automatically included into ATIS broadcasts.
