Any significant AFCS failure that has caused the majority of the AFCS to shut down will be indicated by which caution?

• A. AFCS PARTIAL
• B. ECS FAIL
• C. AFCS FAIL
• D. AUTOPILOT OFF

Answer: (C)

When a significant AFCS fault reduces most of the Automatic Flight Control System to a shutdown state, the indication shown is AFCS FAIL. This caution is the system’s way of telling you that the AFCS has encountered a major fault and is no longer providing stabilization or autopilot functions, so you’d be flying with manual control or with only limited AFCS capability. Understanding the other cues helps: AFCS PARTIAL means some AFCS channels are still available, but not the full system, so degradation rather than a complete shutdown. ECS FAIL points to a problem in the Environmental/Electronic Control System, not the AFCS itself. Autopilot OFF simply means the autopilot mode is disengaged, not that the AFCS has failed.
