The real question here is, when he gets a real OE INOP just past the critical point, whether he's going to get out his protractor and ruler to measure all the angles and distances in order to remain compliant?
Obviously, remembering the key numbers could come in quite handy at such a time. However, the question he's asking here seems far more relevant to flight operations planning, than to to a pre-TO briefing. e.g. Can we fly a B777 between airports X and Y safely and in compliance? Rather than what does he do when he gets a birdstrike on #2 just after rotation when there's a big TV mast 100m off the centreline at 2km from the boundary fence.
