Question 33Navigation Problems70% to pass
On 29 April your 0300 ZT DR position is LAT 28°39' N, LONG 168°03' E. You are on course 108°T at a speed of 22 knots. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?
AI Explanation
The correct answer is B) Moon, Alpheratz, Polaris.
This is the correct answer because the three celestial bodies listed - the Moon, Alpheratz, and Polaris - are well-suited for a fix at the given star time (0300 ZT) based on their magnitude, azimuth, and altitude. The Moon is a bright navigational body, Alpheratz is a prominent star in the constellation Andromeda, and Polaris is the North Star, which is always high in the northern sky and useful for celestial navigation.
The other answer choices are not as well-suited. Option A) Deneb, Dubhe, Zubenelgenubi are not as prominent or useful for navigation at the given time and location. Option C) Moon, Altair, Sabik includes Altair and Sabik, which may not be as easily identifiable or prominent as the bodies in the correct answer. Option D) Venus, Polaris, Arcturus does not include the Moon, which is a crucial navigational body at the given time.
