Question 111Navigation Problems70% to pass
On 3 February your 0550 zone time DR position is LAT 26°16.0' N, LONG 112°05.0' W. 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 A) Spica, Kochab, Rasalhague.
This is the correct answer because the criteria for selecting the three bodies best suited for a fix at star time are that they should be of significant magnitude, have a favorable azimuth, and be at a suitable altitude. Spica, Kochab, and Rasalhague meet these criteria, as they are bright stars (significant magnitude) located at different azimuths and with an appropriate altitude for a celestial navigation fix at the given position and time.
The other options are incorrect because they do not meet the criteria as effectively. For example, option B includes Vega and Dubhe, which are not as favorably positioned as Spica, Kochab, and Rasalhague, while option C includes the planet Saturn, which is not a star and may not be as suitable for a celestial navigation fix.
