Just achieved a 500kg increase in allowable take off weight for a company B737-800 through using an MAC setting of 25% in the take off performance calculation- i.e a more rearward c of g setting than "optimum".
I assume that this allows less stab trim to be used, therefore less drag and quicker acceleration to rotation, can any one confirm this to be correct and advise if this creates any handling problems during the take off roll, i.e will the aircraft be light on the nose gear etc? Any feedback appreciated...
