fabvirgil,
You are not the only one posting here with a long and intimate acquaintance with the B747, all models. I don't really believe anybody was suggesting that Boeing got it wrong, just stating a few facts of life. There is nothing in any of my comments that is inconsistent with the AFM for any model.
Did you ever have a low speed abort with the thrust set?? In the real world, as opposed to the simulator?
Indeed, differing only in degree, the same thing could be said about any of the four-engine jets. One night in Tokyo, many years ago, I saw the results of a mishandled abort in a DC-8 --- the aircraft was a write-off.
Perhaps, despite your experience, reading the FAA study on real world aborts, or the Boeing studies on same, would be of real value.
