IMS4 ARWIS provides the airport authorities with essential runway surface condition data. Using the real-time collected measurements from the field sensors as well as forecasts from the integrated model the system detects and predicts the runway surface conditions to support decision-making on runway treatment and to report runway conditions in a standardized way.
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 and ICAO Doc 9981 (GRF implementation) in effect from November 05, 2020 (due to COVID-19 postponed to 2021).
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 a standalone one with options for upgrades during the system's lifetime or can be fully integrated within the IMS4 Automated Weather Observation System.
