CAAS (Common Avionics Architecture System) is a modular, open-systems digital cockpit avionics suite developed by Rockwell Collins (now Collins Aerospace, part of RTX) for U.S. Army rotary-wing aircraft. It integrates communications, navigation, flight management, mission subsystems, and sensors into a unified, glass-cockpit environment featuring multifunction displays (MFDs), control display units, and advanced processing.

Key features include:

  • Open architecture (based on Flight2™ MOSA design) for flexibility, future upgrades, and reduced lifecycle costs through common components across platforms.
  • Combat-proven, off-the-shelf hardware to lower risk and enhance reliability.
  • Enhanced situational awareness via integrated sensors (e.g., FLIR, multi-mode radar, GPS/INS) and reduced pilot workload through automated decision aiding.

CAAS is standard on the CH-47F Chinook, MH-47G (special operations variant), MH-60M Black Hawk, and other Army helicopters, including those operated by the 160th SOAR (Night Stalkers). It supports demanding night/low-level/tactical missions with superior interoperability and survivability.
