Question 1746Navigation General
70% to passThe LMT of LAN is 1210. Your longitude is 70°30'E. Which time would you use to enter the Nautical Almanac to determine the declination of the Sun at LAN?
A
1842
B
1652
C
0728
D
0652
AI Explanation
The correct answer is C) 0728. To determine the correct time to use in the Nautical Almanac, we need to convert the Local Mean Time (LMT) of Local Apparent Noon (LAN) to Greenwich Mean Time (GMT). The LMT of LAN is 1210, and your longitude is 70°30'E. To convert LMT to GMT, we add the longitude in time (70°30'E = 4h 42m), which gives us 1210 + 4h 42m = 1652 GMT. Therefore, the time you would use to enter the Nautical Almanac to determine the declination of the Sun at LAN is 0728 GMT, which corresponds to 1652 local time. The other options are incorrect because they do not properly account for the conversion from LMT to GMT.
