Re: So... is he an engineer?
An Engineer is someone who engineers things.
A Chartered Engineer is someone who engineers things and has also paid a fee to have some letters after their name, perhaps after some form of evaluation of their abilities.
The important word is "Chartered", not "Engineer".
I, for example, went through the IMechE's MPDS training system, and could, if I paid the fee, join them to become a Chartered Mechnical Engineer. I didn't feel the need, and now I'm a Software Engineer anyway. I feel no need to become a Chartered Software Engineer.
