Crab said it all really - most of us are almost on the same hymn sheet.
Now that r22 butters has left the building common sense will prevail.
If I said fanny to an american - they would all assume I'm talking about someone's bum!
If I said spanner, they wouldn't understand what that meant.
If I said closet, it would mean a toilet. In america it means cupboard.
So I'm of the opinion that americans or american trained pilots use SWP to often describe (our) VRS.
American trained pilots have never heard of IVRS.
American trained pilots use Power Settling (PS) where others use/mean: SWP.
Perhaps if we based our conversations around these 'langauage differences', we would be able to interprete matters more readily.
Expert helo pilots on this thread - tend to be singing from the same sonnet sheet.......sorry hymn sheet.
The important bit is to get the message of each (SWP/PS/VRS/IVRS) across in a language the ab initio understands and avoids the circumstances that allows any of these to flourish.
Let's not get our knickers / pants in a twist / helix
