The wing carry-through structure usually constrains the cabin by

  • A.Intruding on floor or hold space
  • B.Restricting the cabin's width
  • C.Reducing the cabin's pressurisation
  • D.Limiting the number of exits

Answer: A

Correct answer: Intruding on floor or hold space

The wing centre section must be carried continuously through the fuselage so the bending moment passes across without a joint, and that box occupies real volume.

On a low-wing transport it sits below the cabin floor and eats into the hold, which is why the hold is divided into forward and aft compartments with the centre section between. On a high-wing aircraft it crosses above the cabin instead. Width and pressurisation are unaffected; it is depth that is lost.
