Question. Aircraft is belting down the runway and 20 knots below V1 on the wet runway the ever alert 500 hour first officer sees a flickering oil pressure gauge and because he is momentarily transfixed with doubt whether or not to bring it to the attention of the captain who is PF, decides to take what he judges as the safest action and that is when in doubt call STOP, STOP, STOP...
So he shouts out loud STOP, STOP, STOP.
The captain is instantly nonplussed. The first officer is obviously serious and the captain must decide either to give him the benefit of the doubt and STOPx3 - or, not having a clue what the first officer is on about, says ****** that - I am continuing the take off and sort out the "problem" in the air.
Who is right? And if you were the captain what would you do? Obey the first officers command? Or ignore it?
