What does a caution signify regarding aircraft systems?

A caution in the context of aircraft systems signifies a potential danger to a system. This means that while the aircraft may still be operable, there is an indication that a system is not functioning optimally or may encounter issues that could compromise performance or safety if not addressed. Cautions are often utilized to alert the crew to monitor the situation closely and take appropriate actions to mitigate risks associated with system malfunctions or abnormalities. Understanding this distinction is crucial for aircraft maintenance and operational safety, as it prompts timely interventions to prevent escalations into more severe issues.
