Question 9B5

For vessels on international voyages, Part 80.84 of the FCC rules specifies the required documents and publications, particularly for those subject to the Safety Convention. * **ITU List IV (List of Coast Stations)** and **ITU List V (List of Ship Stations and Maritime Mobile Service Identifier Assignments)** are essential reference documents providing details on frequencies, call signs, and services of maritime stations worldwide. * An **Appropriate Safety Convention Certificate** confirms the vessel's compliance with international safety standards, including radio equipment. * The **ITU Manual for Use by the Maritime Mobile and Maritime Mobile-Satellite Services** (often referred to as the ITU manual for Maritime Mobile stations) contains comprehensive operational procedures and regulations for the maritime radio service. Option A correctly lists these three required items. Options B and C are incorrect because the "ITU Master Plan of GMDSS Coast stations" is not explicitly required onboard as a separate document in the same way List IV is. Option D is incorrect because the relevant manual is published by the **ITU**, not the IMO.
