What is the role of read-back in ensuring warrant accuracy?

• A. It delays operations
• B. It provides explicit confirmation that the dispatcher has correctly understood the details
• C. It is optional
• D. It is used only for new crews

Answer: (B)

Read-back is a safety check in track warrant control communications. After the dispatcher issues a warrant, the crew repeats back the key details to confirm they heard and understand exactly what was issued. This explicit confirmation ensures the dispatcher and crew share the same information about track limits, authority, block sections, speeds, and other terms. If the read-back doesn’t match what was issued, the details are corrected right away before any movement, preventing misinterpretation that could lead to an unsafe operation. It’s a standard, non-optional practice used with every warrant and every crew, not just new ones.
