- For map reading and navigation instructors. This video explains one method of calculating the exact results of a compass bearing error.
Mistakes do occasionally happen and, as an instructor, it is our role to be able to explain “exactly” what the results of an error would be. Using the method shown in the video it is very simple to give the “what would have happened” without the need for a course participant to walk into a, possibly, hazardous area.
This is the video which is mentioned in the Magnetic Declination Simplified video
If you don't remember the formula, you can calculate on half the triangle with the definition for: sin(A)= Opposite/Hypotenuse. Then you double the result. In our case it becomes. [ x= Radius * sin(45) ] then you double x
Excellent explanation. Please keep them coming. one small complaint, no waffle!
This is an old video (about a year ago - pre waffle). I had to re-upload it as there was a copywrite claim. This is the first claim I have had against me, but I'm told it is a common TH-cam scam. Oh well, that's the world we live in.
Thanks. Really appreciate the back to basics explanation, makes it much easier to understand and apply.
There's waffle on the official Part 2! 😅
Thanks for the video. I'd never used the chord method. I use the TOA formula which comes out very close. Love your videos..keep them coming
Sir, thank you for yet another excellent video.
Good teacher. If I were not in America, I'd definitely be interested in attending a course.
Great video thanks, as you said it’s not something you’ll ever be likely to use but interesting to know
If you take regular short walk bearing checks you should have less error. Just wondering how they get on in space travel?
👍
CHORD
2*R*(A°/2)”sin”=
2*456m*(90°/2)press sin & =
=644.8m
2x Distance(m) x
(error/2) “sin”=
pressing the sin button at the end on my Iphone/mac then = worked (brackets or no brackets still worked
Shiiiiiiiit,I did that math In me head , yup 😂! Simple 😂😂I understood everything you said Before you said it 😂😂😂😂. P.s. None told me There was going to be complex math problems in this new orienteering hobby I have taken up.🎉
I'm sorry, are you saying "ch"ord? Pretty sure it's "k"ord.
A chord by any other name would be as straight. This guy’s channel is otherwise so brilliant that maybe he should be cut some slack on this one. Cheers.
Regardless, he's a genius and we all know what he means.
Hi
I am a little bit disappointed where is the waffle
Maybe because you don't have tea😂
Thanks
