In a scenario where the stabilator indicator shows yellow, what mode is the stabilator in?

• A. the stabilator is in auto mode
• B. the stabilator is degraded
• C. the stabilator is in manual mode
• D. the stabilator is locked

Answer: (C)

The color shown on the stabilator indicator communicates how the stabilator is being controlled. When the indicator is yellow, the stabilator is in manual mode. This means AFCS (the automatic flight control system) is not actively steering the stabilator and the pilot’s control inputs on the flight controls are directly commanding the stabilator position. In this state you’re responsible for the stabilator position and any trim needs, rather than relying on automatic stabilization. If you needed to re-engage automatic control, you would switch back to auto mode and the AFCS would again manage the stabilator. Yellow specifically flags manual operation rather than degraded or locked conditions, which would show different indicators.
