What system generates messages including warnings or cautions upon failure?

The Flight Warning System (FWS) is responsible for generating messages that include warnings and cautions in the event of a system failure. This system monitors various aircraft parameters and operational conditions, providing alerts to the flight crew about potential issues that could affect the safety and performance of the aircraft.

By utilizing a series of sensors and inputs from different systems throughout the aircraft, the FWS evaluates the data continuously. Upon detecting any anomaly or threshold exceedance, it activates visual and auditory alerts to ensure that the pilots are aware of the situation and can take appropriate action if necessary. This makes the FWS a critical component in enhancing situational awareness and ensuring safe operation, especially in high-stress situations.

The other systems listed, while important for their respective functions, do not serve the specific role of generating these vital caution and warning messages based on system performance and failures.
