What action is required to change an issued track warrant?

• A. Amend the existing warrant
• B. Issue a new track warrant voiding the old one
• C. Change the OK time on the existing warrant
• D. Notify the crew by radio

Answer: (B)

When anything about a track warrant needs to change, the proper procedure is to issue a new track warrant that voids the old one. This ensures there is a single, current authority in effect and prevents confusion from multiple or conflicting directives. Amending the existing warrant or changing its OK time on the fly could leave terms in doubt or create mismatched instructions, which is not allowed. Radio notification to the crew is important for communication, but it does not replace the formal act of reissuing the warrant. The new warrant explicitly outlines the updated authority and cancels the previous one, keeping the safety record clear and auditable.
