• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Warning tags are maintenance tools used on the ground to indicate an item should not be operated while work is being done. They rely on human action to stay in place, and during flight there’s no reliable way to ensure they remain visible or effective. To guarantee a system stays deactivated for flight, it’s de-energized by locking the circuit breaker with a collar. This provides positive, tamper‑resistant isolation, so the system cannot be reenergized during flight and there’s a clear indicator that the item is out of service. So, the statement is true: warning tags will not be used in-flight; the proper method is a circuit breaker collar to disable the system for flight.
