CH is 120°. Deviation is +4°. Variation is 5° W. Wind correction angle is 8° Right. TT is: (choose below)
111°
127°
113°
129°
120-4-5-8=103 (T) ???
CH is 224°. Deviation is -3°. Variation is 4° W. TH is:
217°
223°
225°
231°
224+3-4 = 223(T) = answer b
CH is 317°. Deviation is +3°. Variation is 5° W. Wind correction angle is 10° right. TT is:
309°
305°
329°
325°
317-3-5-10 = 299 (T) ???
CH is 098°. Deviation is +2°. Variation is -8° and drift is 5° Left. TT is:
087°
093°
097°
109°
098-2+8+5 = 109 (T) = answer d
have I gone wrong somewhere on questions 1 and 3 ???
