hmm...got me thinking here...
I've read this thread with interest, and as a pilot who navigates the busy Manchester/London/Scottish sectors regularly is often asked to report my heading or turn left/right 10 degrees and report heading.
Now my question, do you want to know my exact heading, or a rounded up/down heading to the nearest 5 degrees?
If, lets say, my heading is 323 degrees and you want me to turn right 15 degrees, do you want my heading to be 338 and report it as 340, or to right turn 17 degrees and be heading 340 degrees (having rounded up the figure to make it a whole one?)
