C of G loading question

[JABBARA]

Sure, the elevators should move up,
but my explanation is a little bit different:

CG moves fwd, then the lift induced moment about the cg increases becuse of increased arm between Lift and CG. To counteract or balance this increased moment, tail should create a greater downward force: elevator up.

A side effect: Increased downward force is added up to Weight. So apparent weight of the plane increases. Lift, should also increase to carry this new apparent weight, this means a higher AOA for a given speed.

So a higher AOA results: More Fuel burnt, lower max alt, higher stall speed, lower max speed.

Only good thing is a more stabilized airplane.

An addition: Yes, some books confuses me too, with "elevator nose up/down"
Elevator nose up/down: Elevator movement to drive the airplane`s nose up/down=Elevator trailing edge is up/down
