What does the TAD OFF annunciator indicate about the rudder?

• A. Rudder is active
• B. Rudder TAD is recalibrated
• C. Rudder TAD is off
• D. Rudder is malfunctioning

Answer: (C)

The TAD OFF annunciator indicates that the rudder's Turn Coordination and Automatic Damping (TAD) system is not currently active. This means that the automatic inputs to the rudder, which help to stabilize the aircraft during various flight conditions, are disabled. When this indicator is illuminated, pilots should be aware that any rudder assistance normally provided by the TAD system will not be available, and they will need to rely on manual rudder inputs for control.

Understanding the implications of the TAD OFF status is critical for flight safety, as it may affect the aircraft's handling characteristics, especially during turns or in response to crosswinds. Correctly identifying this condition allows pilots to make informed decisions regarding their flight control management.
