Landing weight limit relaxed by the whole takeoff fuel · case 03

Short sectors with lots of reserve fuel report a higher allowed takeoff weight than the landing limit permits.

Case contract

Input weights in kg. Allowed takeoff weight = lowest of MTOW, MLW+trip fuel, MZFW+takeoff fuel, MRW-taxi fuel; ties go to the earlier entry in that order. Allowed payload = allowed TOW - OEW - takeoff fuel, floored at 0. Return [allowed TOW, payload, limiting name].

Why this case matters

The classic loadsheet payload limitation takes the lowest of four structural limits, each translated to a takeoff weight with the correct fuel quantity.

One recorded failure
