In addition to the TRIM OFF annunciator, actuating the trim interrupt button will also illuminate the ______ annunciator light.

Actuating the trim interrupt button serves a specific purpose in maintaining safety and control during flight operations. When the trim interrupt button is activated, it not only deactivates the trim system but also illuminates the TAD OFF annunciator light. The TAD (Turn Coordination and Stability Augmentation System) is crucial for maintaining control during turns and providing stability; thus, indicating that it is off is important for the pilot's situational awareness. This alert serves as a reminder that the system is not functioning, enabling the pilot to take necessary actions to maintain control under different flight conditions.

In this context, the other annunciator lights mentioned do not directly relate to the activation of the trim interrupt button, highlighting the specific operational role of the TAD OFF light in conjunction with the trim interrupt system.
