I’m sorry, but there is so much rubbish being spoken here. Yes the classic B747 does have similarities to the B744, they both have a hump! But it’s the automatics the auto throttle system which needs to be understood.
Forget all the rubbish about nose wheel steering etc. Ignore the slippery runway, it was damp, possibly wet.
I have around 15000 hours on the B747, most of it as a skipper on the B744.
Yes this is a ‘rumour’ network, but come on. This is why Pprune is akin to the U.K. Daily Mail.
A low speed reject in a B744 is tricky, but we train for it.....every 6 months. If you can’t do it....don’t fly it.
But at the end of the day SOPs cover it, don’t have a go at Boeing, don’t insinuate design flaws. Don’t compare it to other aircraft, when you obviously don’t understand the systems. It’s nothing like the ‘classic’, I know I flew the classic for five years......twenty more on the 400 variant.
FACT 90 degrees off centreline at low speed, in the grass, is gross pilot error. Regardless of any report. Here ends the lesson.
