aeroncaman - not sure what your point is. I'm not suggesting that we change the planning. We still plan for the worst case - a failure at V1. However, in the event that both engines keep running until we get to V2+20 we can then retract the flaps and get a better rate of climb. We also have an aircraft thats easier to fly. And we have scheduled one engine inoperative data for that portion of the climb (I just posted a link to it). There is no downside - the problem has been that we are not doing what the manufacturer says, we've all been doing what we have been taught incorrectly to do.
