The American version of the aeroplane will flare and retard but the A/P willnot keep you on the centre line (unless rudder channel is installed)
The French version of the aeroplane will flare, not retard (calls you a retard) but will keep you nicely placed on the center line until A/P disconnect.
Boeing NG a/c are only 3B rated unless fitted (at huge expense) with a rudder channel.
As to to the question asked initially.....I can only ask Bernie Waddington, Mr CAA/JAA queston setter. (Formally of CABAIR).
