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? -- Terry firstname.lastname@example.org "Anyone who thinks they can hold the company responsible for what I say has more lawyers than sense."
