Can we hear from those that have been in real rejected takeoffs (not training) as to how the situation was handled.
was the responsibility discussed in the cockpit beforehand?
Did the captain perform the reject without consultation (e.g. PNF response)?
Did the PNF call out abort?
Was the right seat flying the aircraft and if so performed the abort on his decision or only via the captains command?
To me it makes no difference (subject to reading further posts) as long as it is agreed beforehand.
