Why only 2 in the flight deck?

The FE handles the throttle on the Tu-154 as well!
As for the sim version, it sure can be a handful when you are trying to fly a plane alone which was designed to be flown by three or four people! I guess you really need a full crew if the systems are going to be as user-unfriendly as they are.  :)  (It sure is fun though!)
