David, I’m reading your book and working all the exercises. I have the Kindle edition so I have had to print the plotting sheet for this exercise so there is the possibility of some distortion in my copy and therefor my answers.

This is a plotting exercise involving bearings from per plotted points in the book.
The answers (in the book) to the problems are
6a Bearing from Point B to A 316 deg.,
6b Bearing from Point A to B 136 deg.,
6c Bearing from Point D to A 159 deg.,and
6d Bearing from Point B to C 024 deg.
These appear to be the reciprocal of the bearing.

The answers I got for bearings were:

6a 136 deg.
6b 317 deg. (I know 6b should be closer to 316 deg.)
6c 339 deg.
6d 204 deg.

Is there an error in the book or is it me?

Hi John,

Thanks for catching this.

Your answers indeed correct. Although we do get 316 for 6b, and 340 for 6c.

It will be fixed in the next printing and I will add it to the errata at starpath.com/celnavbook.
