I spent 16 years flying 3 crew, and 19 years flying 2 crew. When you need a Flight Engineer because of the design of the aeroplane, it's great. When you fly more modern gear and it's designed for 2 crew, dare I say, it's even better. The time of Flight Engineers in civil flying has passed. The new equipment does not need them. Even a 747-400 is quite adequately and safely crewed by 2. And it works well. It does mean there is slightly more to do and you must be a bit better organised (nobody to pass you manuals/charts at busy times), but do not fear- you will enjoy it.
