cadaha - fantastic. First heard that a while back from a mate learning to glide. It's still as funny as then!!
A quick question (asked mazzy - he asked for me to post it on here - sure it's nothing to do with his abilities to answer my question. Just want to help others too!)
Anyway - magnetic variation.
I understand that you need to vary your heading, because of this variation. But, I'm unsure as to where to add or take off...
If, where I'm flying there's 4W magnetic variation, and I'm flying 175, I'd alter my course to 179. Ie 4 degrees towards west.
However, if I'm flying 290 would I add 4 degrees again, or take them off. Logically I'd say taking off TOWARDS west would make sense to get 286...but I'm not sure.
Anyone help?
Edited: Mazzy has indeed given me a very helpful answer (thanks):
If the mag variation is west ADD to your heading.
If the mag variation is east SUBTRACT from your heading.
"WEST IS BEST EAST IS LEAST"
I was confused - thought you'd add or subtract towards west, if the magnetica variation was west.
I'll leave this on, someone else may ask the same one day.
