Capt. Fathom, so if we dont use the speed brake the distance to stop would increase significantly? Rubiks is making me think twice about whether significant lift is generated during TO roll. For landing of course it is extremely important. But for TO, the wings are made for high speed flight and is not so curved as mentioned. I think they might not be so critical that you must absolutely deploy them within a fraction of a second. The airplane weighs 300T and the weight is not on the wheels?? Just wandering if numbers are available for RTO with or without spdbrakes.
