A STAB DEGRADED advisory indicates that the stabilator is in which mode and has reduced functionality?

• A. Manual Mode
• B. Limited Auto Mode, with reduced functionality
• C. Auto Mode
• D. Off

Answer: (B)

STAB DEGRADED means the stabilator control system has faulted enough that the flight control computer switches to a safe, limited automatic stabilization state rather than full automatic control. In this degraded state, the stabilator can still provide automatic stabilization and trim, but with restricted authority and functionality. Some auto features or full pitch control protections may be unavailable, requiring the pilot to rely more on manual control while still benefiting from reduced stabilization assistance. So the advisory points to a mode where automatic stabilization is present but limited, rather than full Auto Mode, manual control with no auto support, or no stabilator command at all.
