What is required when changing a track warrant's authority by issuing a new warrant?

• A. The old warrant remains valid
• B. A new track warrant must be issued voiding the track warrant to be changed
• C. The OK time is updated on the existing warrant
• D. The crew is notified by phone

Answer: (B)

When changing a track warrant’s authority, you must issue a new track warrant that voids the previous one. Warrants aren’t amended or extended; a fresh document is issued so there’s a single, current authority governing the track. This creates a clear, auditable record and prevents overlapping permissions that could cause unsafe or confusing operations. Leaving the old warrant valid or updating its OK time doesn’t properly change the legal authority, and while crew notification is important, it doesn’t replace the formal act of issuing and voiding warrants.
