Question 86Navigation Problems
70% to passOn 3 February your 0547 zone time DR position is LAT 24°18.5' N, LONG 167°25.0' E. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?
A
Jupiter, Denebola, Regulus
B
Regulus, Deneb, Antares
C
Altair, Saturn, Regulus
D
Arcturus, Kochab, Venus
AI Explanation
The correct answer is B) Regulus, Deneb, Antares. This is the correct answer because at the given position and time, Regulus, Deneb, and Antares are the three celestial bodies that are best suited for obtaining a navigational fix. These three stars are bright, well-separated in azimuth, and have suitable altitudes for reliable celestial navigation at that location and time. The other answer choices are incorrect because they do not include the optimal combination of stars for a celestial fix at the given position and time. For example, Jupiter and Venus are planets, not stars, and Arcturus and Kochab are not as well-suited for this particular celestial navigation scenario.
