How will communication be carried out between a ship and a SAR helicopter, According most circumstances? On 410KHz On VHF Ch 16 On 121.5MHz On VHF Ch 70. Saya Tidak Tahu.

B

The question posits a rescue scenario where a ship is attempting to communicate with a Search and Rescue (SAR) helicopter. These kinds of transmissions generally follow a set of established frequencies to ensure effective communication. Looking at the answers:A) On 410KHz - This answer is unlikely because 410KHz is typically too low of a frequency for this type of communication. The actual frequency depends regionally and on the nature of the transmission (voice, digital, emergency, etc.), but they typically lie in the VHF (Very High Frequency) or UHF (Ultra High Frequency) ranges.B) On VHF Ch 16 - This answer is a possible choice. Channel 16 (156.800MHz) is internationally recognized as the maritime VHF radio distress frequency.C) On 121.5MHz - This is unlikely to be an accurate method of communication for a ship and helicopter. While 121.5MHz is an international emergency frequency, it tends to be used for general aviation, not maritime communication.D) On VHF Ch 70 - Although this is within the VHF range, channel 70 is commonly used for Digital Selective Calling, not voice communication.As your question specifically pertains to a communication channel during a SAR operation.
