En situación l= 35º 50´ N y L = 006º 00´ W y nos dirigimos a una situación l = 35º 57´ N y L = 005º 28´ W, dm = 3º NW y Desvío = 3º NW. Se pide el Ra.At l = 35º 50'N and L = 006º 00'W we head for l = 35º 57'N and L = 005º 28'W, dm = 3º NW and Deviation = 3º NW. Find the compass course (Ra).
Show the answer
Correct answer: d) Ra = 081º
Why it is correct
True course: about 075º. Total correction: −3 − 3 = −6. Ra = 075 + 6 = 081.
Why the others are not
- a) It applies the correction with the wrong sign.
- b) This does not follow from the data.
- c) That is the true course, uncorrected.
How to work it out in the exam
- True to compass: subtract total correction. Subtracting −6 adds 6.
