I know what he means by SWP and it is the wrong terminology - even the FAA have caught up now.
Its not "the wrong terminology" its just different cultures using the same words to describe different things.
,...and the FAA hasn't "caught up" they just gave up and removed the term SWP from the books. That thing you and Canada call SWP is still too ridiculous to be in our books. In the US (officially) the term SWP doesn't mean anything anymore.
