General Nav Problem 1

[Jinkster]

Just working through the Oxford feedback and come to a problem.

You are heading 080T when you get a range and bearning fix from your AWR on a headland at 185nm 30deg left of the nose. What true bearing do you plot on the chart?

a) 050 from the headland using headlands meridian
b) 050 from the headland using aircrafts meridian
c) 230 from the headland using the headlands meridian
d) 230 from the headland using the aicrafts meridian.

The correct answer is 'd' but I am getting 330 from the headland using the aircrafts meridian - is this question a typo or is it me!! :rolleyes:

Thanks in advance

Your heading is 080T and the relative bearing is 30 degrees left, making your true bearing to the feature 050T (080 - 30, or alternatively 080 + 330 - 360). Hence the true bearing from the feature is simply the reciprocal of this: 050 + 180, which is 230T,
