Question 151 Deck Safety

70% to pass

In radiotelephone communications, the prefix PAN-PAN indicates that _______________.

A the message following is a meteorological warning
B a calling station has an urgent message about the safety of a person
C a ship is threatened by grave and imminent danger and requests immediate assistance
D the message following the prefix will be about the safety of navigation
AI Explanation

The correct answer is B) a calling station has an urgent message about the safety of a person. The prefix "PAN-PAN" is used in radiotelephone communications to indicate an urgent situation that does not pose an immediate threat to life or the vessel, but requires immediate attention. This is distinct from the "MAYDAY" prefix, which indicates a distress situation where a person, ship, or aircraft is threatened by grave and imminent danger and requires immediate assistance. The other options are incorrect because A) refers to a meteorological warning, C) refers to a distress situation, and D) refers to a message about the safety of navigation, which would not be indicated by the "PAN-PAN" prefix.
