Which bi-annual publication contains descriptions of every light and ATONs?

• A. COMDTPUB P16502.6
• B. NSP- National SAR Plan
• C. MARPOL 73/78
• D. Allied Communications Publication

Answer: (A)

The main idea here is knowing where official, up-to-date descriptions of every light and Aids to Navigation (ATON) are published. The bi-annual reference that lists all lights, lights’ characteristics, locations, and ATON descriptions is the Coast Guard publication identified as COMDTPUB P16502.6. This publication is specifically dedicated to Aids to Navigation, ensuring mariners have a single authoritative source for every light and ATON. The other choices don’t serve this purpose: a National SAR Plan outlines search and rescue coordination, MARPOL 73/78 covers pollution prevention for ships, and Allied Communications Publications deal with naval communications procedures. So the publication that consolidates all lights and ATONs is the COMDTPUB P16502.6 reference.
