What would a typical V1 speed be on the L-1011? On the 737/A319 it can be around 125 to 150. That gives an FO a few seconds to initiate action to stop. Remembering that the decision should already have been made by no response to the second call.
If it was me, and I called out 80 knots and no response, my first action would definitely involve a glance over at El Capitan, immediately, and at least raising my voice a large amount for the next call - however if he/she is doing the whole slumping over/frothing at the mouth/red-faced (usual for the 5th early
) then I'm stopping.
But this is an interesting area, up until very recently I thought it was clear cut, but now seeing some different points of view it appears that FO's should be also making assesment when they line up on what to do if you are about to get some unexpected command time....
