smartTOOLS and smartSTRIPS are core Tower applications that support air traffic controllers in managing daily operations with clarity, efficiency, and real time awareness. smartSTRIPS replaces traditional paper strips with digital flight data strips, helping controllers track flight status, coordinate changes, and maintain consistent operational data across integrated tower systems. smartTOOLS complements this by providing an integrated information and control platform with real time monitoring of the runway systems and meteorological data.

Together, these applications streamline tower workflows, improve situational awareness, and enable safer, more efficient decision making in a modern digital tower environment.
