Just an inquisitive SLF here, trying to get in before the thread is closed *again*..
What does the PF feel when a 737 is nose-heavy ? I would imagine there's heaps of elevator authority available, so it would be possible to just keep pulling back to get the nose to come up to the right "rotate" attitude. But is there a SOP that mandates an RTO if the amount of back stick required is abnormal ? Definitely a moment when the PF earns his wage !
