Question 46F5

A Vessel Data Recorder (VDR) captures a comprehensive set of information about a ship's voyage, similar to an aircraft's "black box," for accident investigation. It records operational data, bridge audio, and communications. Let's examine the options: * **A) Position, Date, Time and Speed:** These are fundamental navigational parameters and are always recorded by a VDR. This is an accurate list. * **B) Heading, VHF radio communications, Position and Depth of water:** Heading (from gyro), VHF radio communications (bridge audio), position (GPS), and depth (echo sounder) are all critical operational and safety data points routinely recorded. This is an accurate list. * **D) Depth of water, Audio from the bridge, Speed and Position:** Again, these are all standard, mandatory VDR recording parameters. This is an accurate list. * **C) Heading, Depth of water, EGC data and Radar:** While Heading, Depth of water, and Radar (display image) are standard VDR recordings, "EGC data" (Enhanced Group Call, part of GMDSS for broadcasting safety information like SafetyNET messages) is generally *not* listed as a mandatory, direct recording parameter for a VDR. The VDR records GMDSS *communications* (like voice radio or DSC alerts sent/received), but not the raw broadcast EGC data itself. Its inclusion makes this list less accurate than the others. Therefore, the list in option C is not an accurate compilation of typical mandatory VDR recordings due to the inclusion of "EGC data."
