Now still, if anybody can explain that approach climb to me, and why we have to check gear struts if it isn't the overweight that decides if a jettison system is there or not.
approach climb = 2.1% or 2.5% single engine, go around flap, gear up, Vac
landing climb 3.2% all engines, landing flap, gear down, Vlc(which may not be less than Vref)
overweight landing checks have to be carried out whenever the aircraft lands above the certified max structural landing weight. Regardless of the weight required to acheive approach and/or landing climb performance.
