ZFW Limited TOGW

Hi

The trim sheets I've seen start with:

Box A = Performance Regulated TOGW

Box B = Max LDG Weight + Trip Fuel = Landing Limited TOGW

Box C = Max ZFW Limit + Takeoff Fuel = Zero Fuel or Fuel Limited TOGW

Max TOGW for the flight = Lowest of A, B or C

If you are above the box A limit, the structure limit is busted at takeoff.

If you are above the box B limit, the structure limit is busted at landing.

But if you are above the box C limit, I dont see any adverse effect, provided you are within box A and B limits.

TOW will be increased by payload or fuel.

Limit uptill which the payload can be increased is the Max ZFW limit.

Limit uptill which the fuel can be increased is box A or B (and of course tank capacity).

So I dont understand how does box C limit the Max TOGW?

Regards
