Thanks Natstrackalpha.
Having recently flown, (A330), I agree that the white sidestick position indicator does now disappear soon after rotation.
So:
You apparently don't monitor yourself a lot then ... At 50 the cross has gone for a while already.
Yep; Confit; you're right.
However, I'm sure that some old A320's I used to fly kept the indication to 50 or 100', because I remember using it to watch what PF did with the controls during take-off and rotation when I was learning to fly the thing.
Another reason for the white sidestick position indicator being displayed on the take-off roll is of course to monitor a sidestick fault. If a sudden control hard over was seen, PM could shout stop! (below V1).
