What occurs when the TRIM AID switch is turned off?

When the TRIM AID switch is turned off, the green TAD OFF annunciator illuminates. This action indicates that the Trim Aid Device (TAD) functionality has been disabled. The TAD assists in automatically adjusting the trim of the aircraft based on flight conditions. By turning off the TRIM AID switch, the pilot recognizes that the TAD is no longer actively managing trim adjustments, and the system will not provide its benefits until reactivated. This helps inform the pilot of the current system status and ensures they are aware that additional manual input may be necessary for effective aircraft control.
