• Great-circle sailing: calculate the distance between 65° 33' S, 093° 14' W and 12° 31' N, 169° 56' E.
• From position 51° 37.8' S, 173° 11.1' W, we observe a body with local hour angle = 104° 05.8' and declination = 19° 38.4' S. At what nautical (circular) azimuth will we see it?
• Calculate the Sun's azimuth at true sunset from position 61° 27.0' S, 122° 47' W, when the Sun's declination is 21° 12.6' N.
