BARKINGMAD
The principal of Airbus FBW is that the AC will do the trimming except in Direct Law, also in roll upto 33 degrees it will hold the bank and pitch . This makes flying very simple, you just create the pitch and bank you desire and leave the stick till you wish to change the picture. The AC behaviour from 50 feet you described is called flare mode. Now imagine trying to land this aeroplane without the flare mode. When you flare the AC would have continued to pitch up and auto trim as long as the sidestick was out of neutral. So everytime you raised the nose you would have to keep neutralising the side stick. Also if you flared more and pushed the stick forward it would have auto trimmed downwards. This AC responce is not going to produce good landings with consistancy. The Airbus created the flare mode in which at 50ft RA it stops trimming, at 30 feet it will memorise the attitude and start pitching down wards so now you can keep the back pressure as required without releasing the stick and keep increasing it as the nose keeps dropping. The main problem initially is getting used to the very small input that is needed on side stick as compared to conventional AC where the pressure and amount of movement of the yoke are much larger. However without bothering about the theory if you proceed with landing as any other AC you can get good consistant results.
