Which document focuses on operating signals as indicated in its title?

• A. ACP 131/ACP 131 US SUPP-1
• B. ACP 121 US SUPP-1
• C. ACP 117 CAN-US SUPP-1
• D. JANAP 128

Answer: (A)

Understanding titles helps you see the scope of a document. A publication whose title includes “Operating Signals” is directly about how signals are operated, procedures, and practices for signaling in operations. That makes it the best match for a question asking which document focuses on operating signals. The document ACP 131/ACP 131 US SUPP-1 explicitly centers on operating signals, so it directly fits the topic referenced in the question. The other publications cover different areas of communications or joint procedures and do not indicate operating signals in their titles, so they aren’t the right fit for this focus.
