Sorry Ferris, wrong again - multiple previous validations in the Uk albeit before any "track to " separation was acceptable. (maybe I'm getting too old!)
I will grant you that I jumped the thread a bit - screaming kids in the background tend to be a bit distracting. However, I beg to differ on who's showing entrenched thinking here. I suggest that you re-read Bern Oulli's two previous posts, he's much more eloquent than I am but I think is trying to express the same idea. ie, we are not only required to provide separation but to
ASSURE it. Big difference. As we all know and BO (unfortunate that) has already stated, there are any number of reason that an aircraft may change track while on "own Nav", the risks of which are greatly diminished by the use of parallel headings. I know which I prefer to stake my licence on.
p.s. very disappointed to see the old US of A's lazy spelling methods have reached the rest of the colonies!! Thru
