Question 508Navigation General
70% to passCivil twilight begins at 1910 zone time on 20 July. Your DR position at that time is LAT 22°16'N, LONG 150°06'W. Which statement concerning the planets available for evening sights is TRUE?
A
Sights of Saturn, Jupiter, and Venus will yield a good three-line-of-position fix.
B
Venus will have a westerly meridian angle.
C
Mars will set about one hour after the Sun sets.
D
Mars, Venus, Jupiter, and Saturn will be above the horizon.
AI Explanation
The correct answer is B) Venus will have a westerly meridian angle. This is correct because at the given time and location, Venus will be on the western side of the meridian (the line of longitude passing through the observer's location) and will therefore have a westerly meridian angle. The other options are incorrect: A) Sights of Saturn, Jupiter, and Venus may not all be available or yield a good three-line-of-position fix at that time. C) Mars will likely set before the Sun, not after. D) Not all of those planets may be above the horizon at the given time and location.
