[quote=stevefoster;27620]Hey Capt. Lee,
What was on the Chief Mate’s celestial part of the test that wasn’t on the 2nd/3rd celestial part of the test?
On sailings I got:
Parallel Cse&Dst and 2nd Pos.,
Mid Lattitude Cse&Dst and 2nd Pos.,
Mercator Cse&Dst and 2nd Pos.
Great Circle
Are there other sailings or just more of the same but more comprehensive?

2-The great circle distance from LAT 35° 57.2’ N, LONG 05° 45.7’ W to LAT 24° 25.3’ N, LONG 83° 02.6’ W is 3966.5 miles and the
initial course is 283.7° T. The latitude of the vertex is 38° 09.4’ N. What is the longitude of the vertex?
3-The latitude of the upper vertex of a great circle is 36° N. What is the latitude of the lower vertex?
4-At 2232 ZT, on 14 July, in DR position LAT 33° 52’ S, LONG 150° 03’ W you observe an amplitude of Jupiter. The planet is about
one Sun’s diameter above the visible horizon and bears 268.5° pgc. The variation is 15° E. What is the gyro error?
5-Parallel Sailing
6-On 19 November, your 0146 ZT position is LAT 33° 48’ N, LONG 25° 22’ E. You observe Polaris bearing 359.8° pgc. At the time of
the observation the helmsman noted that he was heading 224° pgc and 222.5° psc. The variation is 2° E. What is the deviation for
that heading?

8-ZT Sunrise
9-one gnomonic chart
10-ZT of LAN
11-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?
12-On 22 June, your 0424 DR position is LAT 26° 18.5’ N, LONG 124° 18.2’ W. You observe an unidentified star bearing 195° T at an
observed altitude (Ho) of 03° 30.7’. The chronometer reads 00h 23m 24s, and is 01m 32s slow. What star did you observe?
13-Lat by polaris
14-On 18 May, your 1030 ZT DR position is LAT 20° 41’ N, LONG 63° 32’ W. You are on course 106° T, speed 24 knots. Determine
your 1200 position using the following observations of the Sun.
ZONE TIME GHA DECLINATION Ho
1204 61° 54.6’ N 19° 37.6’ 88° 39.7’
1210 63° 24.6’ N 19° 37.7’ 88° 59.2’
Or a 3 star fix. I had a 3 star fix
15-I also got a Pitch problem on my celestial test
