Why on earth would anyone want to use an S-76 to log? It would be the most pointless, money losing exercise in the history of the business.
You can't log with a mirror, you could modify the seat installation to move it to allow for vertical reference work, and install a bubble window - but why?
The S-76 might have a 5000 lb rated hook, but what would it's actual payload be with 1 hour fuel and 5000' DA?
Best consign this concept to the "stupid ideas better never admitted to" file.
