Deck angle is the angle of the passenger cabin floor with respect to the
ground.  It is too expensive to manufacture an aircraft body with the floor
attachments at a different point on each frame.  If one were to design an
airplane in that manner, one would be forced into the expense of making each
fuselage frame different.

The flight deck floor is usually at a slightly different level than the
passenger cabin floor, but parallel to it.

The Lockheed Constellations had an interesting floor design, and I believe
the A300-600 has a 1.5 degree break in the floor somewhere in the aft
cabin.  I could be wrong on the particular Airbus model - Karl?
