Oh one more tricky set...

9 is normal. I'm obviously in
maintain-heading-mode
10 is probably a controller error but I can imagine such a mix-up^H^H^H^H^H^H^H so it would never happen
. Which mode does the pilot think he is in? Which mode does the second controller think he is in?
11 is a pilot trying to be "helpful". Which mode does the second controller think he is in?
So the problem is, on change of frequency, does "heading 320" from the pilot mean to the controller that he will continue that heading?
(Personally, I think "radar heading" is useful in exactly that context.)
