Hi how to use it when to do running fix

[@guyfromcanadayup]

Just humor me. I was planning on being a Boatswain for the Canadian-Forces Navy. I would maybe like to try and work my way up to be a Navigator's Yeoman. What type of mathematical knowledge would I need to study up on to do so? all I know is grade 9 & 10 math sort of :/.

[@marcheritier4]

Well being an Englishman , I do not know what level grade 9/10 maths is, but if it helps, the most applicable branch of Maths would be trigonometry. You would I guess certainly need a full understanding of Sin/Cos/Tan and perhaps the Sine Rule and Cosine Rule for the solution of non right- angled triangles. Beyond this would be Spherical trig but check the Curriculum requirements. Basic conversions eg 1nm = 1852 metres etc etc would also be essential i feel. Hope this helps.

Great video Mike. Is this video protected by copyright or can I download it for use with my navigation class?

[@flamenco1961]

Where does one get the magnetic variation?

[@JimRudman]

It is shown within the compass rose on the charts

[@csicrawlspace]

Where do you apply the deviation?

[@TOMVUTHEPIMP]

The chart will tell you in the center of the compass rose what the deviation is.
