747-400 Design

You will notice about halfway along the fuselage the roof of the aircraft dips down and remains so along to the rear. I'm interested to know why this is and if its a crucial design feature?

I think it's that the upper line of the fuselage goes up near the forward end because the 747 has a upper deck in the passenger compartment. 🙂

Yes, the upper deck is the first class compartment. It doesn't extend all of the way down the fuselage because the aircraft would be too heavy for the current 4 engines and current wingspan.

I put it the wrong way round. Great demonstration pic Jon! 😉
I like the design of a jumbo very much. 🙂
It was designed that way because the craft was originally meant for cargo only...Boeing thought everyone would be flying supersonic with the advent of concorde. Obviously the "hump" means that more cargo can be contained in the lower deck and the nose can be raised for easier and quicker loading and unloading 😉
