The 737 NG has the option to show round dials in their otherwise full glass cockpits. Not many airlines use that option. Why?
Have helped design elements of the A330 and A340 cockpit when seconded to Airbus at Toulouse back in the mid 90s I could tell you why and I could tell you what the process is but you would not believe it except to say that no line pilot, trainer or examiner had a say in it
