[. . . ] The algorithm was developed for the U. S. Federal Aviation Administration (FAA) by the National Center for Atmospheric Research (NCAR) and patented by the University Corporation for Atmospheric Research Foundation (UCAR). Vaisala is an accredited licensee of the algorithm and can prove compliance with Phase-3 performance. The AviMet LLWAS software runs on the Windows® and Linux environments ·Dataoutputtoexternalsystems ·Printers ·UPSforthecentraldataunit(s) All critical functions of the system can be duplicated to ensure uninterrupted flow of data. data flow from the runway sensors and monitors the sensor operation. The LLWAS algorithm service does wind shear calculations, and the alarm processing services provide the wind and alarm data to the user interfaces. Software architecture The AviMet LLWAS software consists oftheCDUsoftwareandworkstation software. TheCDUsoftware monitors and controls the system's operation. The workstation software is an easy-to-use interface for enduser applications. Workstations The system configuration defines the number of workstations and their types, which have pre-configured environments and differing sets of software applications. The commonly used workstation types are Weather View, Forecaster, Observer, and Remote Control and Maintenance workstations. Central data unit The central data unit is the main computer of the AviMet LLWAS system. It collects data from the sensors, performs calculations, and carries out continuous diagnostics of the incoming data and the entire system. TheCDUalsostoresthe measured and calculated data.
