The Integrated Terminal Weather System (ITWS) provides improved integration of weather data into timely, accurate aviation weather information. This is an essential component in reducing delays and improving National Airspace System (NAS) capacity use while enhancing aviation safety. The ITWS will integrate terminal weather data to automatically provide current weather information and predictions in easily understood graphic and textual form, including windshear and microburst predictions, storm cell and lightning information, and terminal area winds aloft. It also provides a 60-minute forecast of anticipated weather conditions.
The information provided by ITWS is displayed to controllers at locations including tower cabs, Terminal Radar Approach Control (TRACONs), and their associated Air Route Traffic Control Centers (ARTCCs). The system facilitates a common situational awareness of severe weather phenomena to air traffic control personnel. Data will also be available to airlines and other airline industry users for their use in planning activities.
