A wise and professional pilot would know where to look in the AIP to confirm whether the information was correct.... it's available online
Yes, certainly, and I am aware of the extract you quoted, thank you for quoting it anyhow.
My query was whether the initial "make contact" call should be "Centre, ABC, taxi", or "Centre, ABC, IFR taxi", since, as
your bold indicates, the requirement does exist to state that you're operating IFR.
Obviously I was not clear enough in my previous post.
