Hi all
I have searched high and low for a good explanation for movement of the drag curve.
I'm primarily trying to understand questions such as:
Aircraft A and Aircraft B are the same type, travelling at the same altitude, at the same speed, in the same ISA conditions. Aircraft B is 20% heavier, what happens to the drag curve
Moves (and then combinations of UP, DOWN, LEFT, RIGHT)
Then going further, the same sort of questions but say Aircraft B extends LE devices, spoilers, gear or flap etc etc
I guess I'm a bit of a visual learner, so if anyone has links to graphs or can explain it in a straight forward manner, that'd help me out a lot.
