12 Tonne?
What?
Look at Flip Flop Flyer's post. Difference between an A320 and a 737-800 is of the order of 1 tonne. Where on earth does 12 tonnes come from? No way in hell!
I just dug out Boeing's estimates from when they wanted re-equip our fleet, and Airbus' estimates.
A320 OEW 43759kg
737-800 OEW 42829kg (without winglets, by the way - the gap closes when winglets are added).
Again, about 1 tonne difference, nowhere near the 12 tonnes you mentioned! Where on earth did you get that figure from?
