Obviously it is not an issue because the max weights we use are derrived from flight tests while experiencing the tail-down force.

53131 replaces the 48000 in my example. the wing will have to produce enough lift to equal the 53131 plus the tail down force (which will be 1107 lbs.) for a total of 54238 lbs of lift. not a problem! airplane is certified for this. we don't have a published wing-loading limit.
