The MILACAS-XR is an advanced military Traffic Alert and Collision Avoidance System (TCAS) engineered for enhanced situational awareness and airspace safety in high-tempo, multi-platform environments. The “XR” designation stands for Extended Range, reflecting its improved surveillance and detection capabilities over earlier systems like the TPA-81A or standard ETCAS configurations. MILACAS-XR continuously monitors nearby transponder-equipped aircraft, issuing real-time traffic advisories and resolution alerts to help pilots avoid midair collisions. Designed to support the demands of tactical operations and special missions, it offers extended surveillance range, faster response times, and refined threat prioritization logic—making it a critical safety system for military and government aviation platforms.
