Some misguided people do not really know what V1 is. Some authors of light twin factory publications seem not to, either.
On an IPC in a light twin simulator that reasonably replicates engine out performance, the so called ‘V1 cut’ should be done at take off safety speed. At a lesser speed the candidate would be better to do exactly as would be done in the real aeroplane, i.e. put it back on the ground.
Encouraging candidates to fly simulators outside the certification envelope is negative training and could bite a misguided instructor/examiner on the bum big time at an inquest.
