The Honeywell MILACAS-XR is an advanced Traffic Alert and Collision Avoidance System (TCAS) designed specifically for military aircraft. Building upon the proven TPA-100 processor platform, MILACAS-XR offers extended surveillance capabilities, enhanced situational awareness, and compatibility with both military and civilian airspace requirements. Its modular design and integration of hybrid surveillance technologies make it a versatile solution for a wide range of military platforms.

Extended Surveillance and Enhanced Safety Features
MILACAS-XR significantly improves upon previous TCAS systems by doubling the surveillance range to 100 nautical miles in all directions. This extended range is achieved through improved interrogation methods and the incorporation of Hybrid Surveillance, which combines active interrogations with passive reception of Automatic Dependent Surveillance-Broadcast (ADS-B) signals. The system provides timely alerts, issuing Traffic Advisories (TAs) at 48 seconds and Resolution Advisories (RAs) at 35 seconds before potential conflicts, thereby enhancing flight safety and reducing the risk of mid-air collisions.
Modular Design and Broad Platform Compatibility
Available in both 4 Modular Concept Unit (MCU) and 6 MCU configurations, MILACAS-XR offers flexibility to suit various aircraft sizes and mission requirements. The system is designed for easy integration, serving as a direct replacement for the TPA-81A without necessitating modifications to existing aircraft wiring, trays, or antennas. It is approved for installation on a wide range of military aircraft, including the C-130J, V-22, C-27J, CN-295, VH-71, and Kawasaki C-X & P-X.
MILACAS-XR operates within a temperature range of -55°C to +70°C, with a Mean Time Between Failures (MTBF) of up to 30,000 hours, indicating high reliability. The system requires a power input of 50 W nominal (60 W maximum) and supports both 115 Vac and 28 Vdc power sources. Its compliance with ARINC 735A interfaces ensures compatibility with existing avionics systems.
