    Angular separation v. azimuth separation

    I was looking at a book on aerial navigation from the 1940s a few days ago and came across a little bit of confusion (see the attached image). What mistake is this author making? Or, to put it differently, in what parts of the world would this advice be reasonably correct, and in what parts of the world could it be quite wrong?
