Of course the Flight-plans haven't been changed,otherwise someone would have to tell Big Micky that we are wasting all the benefit of those snazzy bent wings. Perhaps if someone had mentioned to the chaps driving that 4 percent extra N1 was available in the cruise by line selecting CON as the limit on the N1 page we might not need to fall out the sky in the first place(this is only a rumour, but I guess it could help if our "woopsy" was a low speed variety) but hell i'm only a simple line pilot, and not the calibre of guy who lambasts the engineers for not being able to clean my polaroid glasses induced stress lines off the windscreen (alledgedly).Think you will find the non wingleted aircraft at same levels as before, and the bent-wings 2 grand lower, as prev poster said optimum and max for these were a little too close ( never did feel very sensible did it? )
