If the weight did indeed scale by [L]^3 - which i in fact doubt
B734, L 36,5m, OEW 33,2T
B773, L 73,9m, OEW 167,8T
So B734 is half the length of the B773.
So 734 weight should be 1/6 th right?; 167,8 / 6 = 28T
Considering the 777 has more composites and is more modern overall
I'd say that weight does scale about L^3
but there's a whole class of medium sized business jets - such as the Lear45
Sure, but what bypass ratio do their engines have compared to their
larger cuisines?
And why don't airlines use them?
