THE WEIGHT OF THE A/C.......nothing else ( in order to keep V2+10 - V2+ 20 after lift off)
Concerning the landing picture ...what happend....nothing , they surely landed safely, once more nothing special here, quite normal to make some correction in short final (cross wind maybe...).What do you think?

Sabena ... Never to be forgotten (12 years already , what a shame !! )
in the landing picture the pilot is applying crosswind correction. there are two types of correction. one it the wing-low meathod (pictured) and the other is crabbing. with crabbing the airplane is pointed into the wind and it flies diagnally. with the wing low meathod the pilot will drop the wing from which the wind is coming and use aileron to maintain drift across the runway. since airplanes can't land sideways the wing low meathod is employed while on short final to maintain centerline in stiff crosswinds and to land safely.
as for climb, airplane performance and it's weight are the only 2 factors when it comes to climb rates. the 747-400 is an exceptional airplane when it comes to climbing. the A340-200/300 is not so good, it has a much more shallow climb angle. the more powerful an airplane the bigger angle of attack (angle between the ground and the flight path of the plane) it can maintain in climbout.
all of the above actions are used daily by all pilots. positive climb refers to the fact that the airplane is gaining altitude after takeoff. it is usually announced prior to gear retraction.
i think that the first 2 pictures are actually taken on appraoch, like the last while the second 2 are climbout shots.
