Obtener la corrección total teniendo como dato el azimut de aguja de la estrella Polar Za= 005º.Find the total compass error (Ct) given that the compass azimuth of Polaris is Za = 005º.
Show the answer
Correct answer: c) 5º NW.
Why it is correct
Taking Polaris at true north (Zv = 000º / 360º), the total compass error is Ct = Zv − Za = 000º − 005º = −5º, which is 5º NW.
Why the others are not
- a) Would be 0º only if the compass azimuth read 000º.
- b) Inverts the sign: Za = 005º means the compass reads high and the correction is negative (NW).
- d) Divides the total compass error by 10.
How to work it out in the exam
- Ct = Zv − Za = 000º − 005º = −5º (5º NW).
