IMS4 ARWIS Airport Runway Weather Information System IMS4 ARWIS provides the airport authorities with the essential runway surface condition data. Using the realtime collected measurements from the field sensors as well as forecasts from the integrated model the system detects and predicts the runway conditions: ice (black ice), freezing rain, accumulation of snow and thaw. Ready for 2020: GLOBAL REPORTING FORMAT ICAO Detection and prediction of runway conditions Compliant with ICAO Annex 14, 7th Edition, Amendment 13b Operational alerts on hazardous phenomena detected or forecast The detected and/or manually observed runway conditions are translated using Runway Condition Assessment Matric (RCAM) into Runway Condition Code (RWYCC ranging from 0 to 6) and disseminated in the form of the Runway Code Report, thus ensuring compliance of the system with the ICAO Annex 14, 7th Edition, Amendment 13b in effect from November 05, 2020. Standalone system or integrated within AWOS / AWDSS The measurements and forecasts-based early warnings contribute to air traffic safety and help in planning the run-way maintenance activities. The system can be installed as standalone one with options of upgrades during the system lifetime or can be fully integrated within the IMS4 Automated Weather Observation System.

manually by the operator or automatically by the system and can disseminated via data exchange networks (AFTN, AMHS, WMO GTS, etc.). The built-in aviation web server provides the local airport controllers as well as remote users with the powerful and efficient web interface. Forecasts and early warnings For the runway condition prediction, IMS4 ARWIS includes interfaces to the Numerical Weather Prediction model (deployed by MicroStep-MIS or operated by the airport / local met service) or imports the TAF / TREND forecasts and the IMS4 ARWIS built-in runway condition model provides the...
