Direction: Strictly write in 4 bond paper, because my activity book have 4 spaces. This is actually for maritime industry course, but I think geometry can do this. Use nautical almanac. Sample calculation: Clatitude by meridian altitude - Sun) On 4th April 1988, In DR position 35°10'N 148° 18°E, the sextant meridian altitude of the sun's lower limb was 60° 10.3. If IE was 2.2' off. the arc. and He was 12 meters, find the latitude and the position line. Sext alt: IE (off) 60° 10.3' (+) 02.2 Obs alt: 60°12.5' Dip (12m): (-) 06.1 App alt: 60.06.4' Tot com LL (1) 15.4' I alt: 60021.8'5 M2D: 29°32.2'N LMT Mer Pass: 04d 12h 03m 00s LIT(E): (-) 09h 53m 12s GMT Mer Pass: Dec (o4d 02 h): 09d 02h 09m 48c 05° 33.8'N (0.9): (+) 00.1 Dec 05° 334°N MZD: 29° 38.2'N Lat 35° 12.1'N PL E-W if similar MZD and Dec are same name-add and retain name. If they are opposite names subtract the smaller one from the larger one and retain the name of larger one.
