Extra fuel burn per passenger
I have a very hazy memory about reading an article some forty years ago, saying that a ten pound briefcase loaded onto a VC10 would cause an extra fuel burn of half a pound per hour of flight. I know that airliners are much more fuel efficient these days, but can anyone tell me how much extra fuel is used per passenger these days?
For simplicity, let's say it's a fairly fat passenger weighing two hundred pounds. This question has been bugging me for some time now & I would really appreciate an answer.
