Question 1762Navigation General70% to pass
Given are the courses and speeds of 4 vessels. The navigator of which vessel would be required to know the actual time of meridian transit in order to take an accurate observation at LAN ?
AI Explanation
The correct answer is B) C 349°T, Sp 25 knots.
The key to this question is determining which vessel's navigator would need to know the actual time of meridian transit in order to take an accurate observation at Local Apparent Noon (LAN). This information is necessary for vessels traveling at high speeds, as their position can change significantly between the time of the observation and LAN.
Of the given options, only vessel B, traveling at 25 knots, is moving fast enough that its position could change enough to require the navigator to know the actual time of meridian transit to accurately determine its position at LAN. The other vessels, traveling at 6, 24, and 7 knots, would not experience significant position changes during this time interval, so their navigators would not need to know the exact time of meridian transit.
