Change the titles?
Flight Detent and N S Fletcher,
As a professional pilot, who has flown both aircraft with flight engineers and ones without, I count the flight engineers as very professional cockpit members.
While it is over the top to expect PPRuNe to change its headings at this late stage, I am sure that the majority of us welcome the FEs as sterling fellows and natural contributors to this forum, so please feel included in the generic term.
FC.
