This thread has got some really arrogant, ignorant contributions. I have made no comments about anybodies capabilities because I don't know.
However,
"I sometimes see a/c making a wide turn onto the runway rolling a while and then applying power. On some runways that's not really safe. If they had a an RTO they would find themself of the runway and if there is a ravin there.....well."
How do you know where their T/O performance calculations were based on? These sort of assumptions reflect inexperienced pilots whatever their age.
