Speed brakes
Hi cosie
the speed brakes are the only fly by wire on the B767, when you pull the handle out of its detent, the speed brakes will pop up and create a slight a short pitching moment, and it takes a little bit of practice to master.
Once I had to diverte (due to a pax weird behavior), the weight was above max landing weight and no jetisson, I cruised with speed brakes slightly out to increase the drag,thus the fuel flow, without compromising the speed. I landed at the max landing weight.
