What caution appears when a coupled FD automatically decouples due to a failure?

• A. Fd Coupler Error
• B. Coupled FD Fault
• C. Fd Couple Fail
• D. Decoupled FD Warning

Answer: (C)

When the flight director is coupled to the flight control system, a failure in that coupling can cause the system to decouple automatically. The alert you’d see is a specific caution that directly names the problem: the coupling between the flight director and the rest of the control system has failed. This is conveyed by the exact phrase “Fd Couple Fail,” which clearly indicates a failure of the FD coupling itself rather than a generic error or a warning about being decoupled. The other phrases describe broader or different issues, but they don’t match the precise indicator the system uses for a coupling failure. If you encounter this, you’d typically reassess the flight mode, consider re-engaging the flight director/coupling, and prepare for manual control as needed.
