What is the primary function of the FIREX-CU?

The primary function of the FIREX-CU is to control fire detection and extinguishing systems. This system is integral to ensuring the safety of both passengers and crew by monitoring potential fire risks and automatically activating suppression mechanisms when a fire is detected. The ability to quickly identify and respond to fire hazards plays a crucial role in maintaining the safety standards of aircraft operations.

While fuel management, electrical system monitoring, and flight navigation are all critical components of an aircraft's overall functionality, they do not pertain to fire safety systems. The specific purpose of the FIREX-CU as a control unit for fire detection and extinguishing functionalities underscores its vital role in emergency response and aircraft safety management.
