V1
Is ssg for real? V1 means V1. Why bother determining a V1 figure if there is any doubt about your actions in the event of it being a consideration.
You can safely abort, all other things being equal, before V1. Above V1 you must GO. Many more people have died as a result of attempts to abort above V1 than have than when the aircraft is flown off and the emergency is handled airborne.
