UIM, or Unmanned Aircraft Systems (UAS) Integration Management, refers to the processes and regulations that govern the safe and efficient use of drones in various airspace. It involves coordinating the operation of unmanned aircraft with manned aircraft to ensure safety and compliance with aviation laws. The goal of UIM is to facilitate the integration of drones into the national airspace system while minimizing risks. This includes developing guidelines for drone operators, establishing communication protocols, and implementing technologies that enhance situational awareness for both drone and manned aircraft pilots.
