Question 551Navigation General

70% to pass

You are proceeding under NCS (Naval Control of Shipping) and wish to send a message concerning an initial enemy contact. Which precedence will you assign this message?

A Z (FLASH)
B R (ROUTINE)
C P (PRIORITY)
D O (IMMEDIATE)
AI Explanation

The correct answer is A) Z (FLASH). When proceeding under NCS (Naval Control of Shipping) and encountering an initial enemy contact, the appropriate precedence for the message is FLASH (Z). This is because FLASH is the highest precedence, reserved for messages of extreme urgency, such as initial enemy contact, which requires immediate action. The FLASH precedence ensures the message is processed and delivered with the utmost priority, as it concerns critical information that may impact the safety and security of naval operations. The other options, such as ROUTINE (R), PRIORITY (P), and IMMEDIATE (O), are not appropriate in this scenario, as they do not convey the same level of urgency and importance as the FLASH precedence.
