Depends on type, but if used then cold by 300'

Those asymetric checks are like those I was taught at OATS when asymetric in the seneca where those critera had to be met before descending below asymetric committal height (300') due to a marginal go-around performance. Perhaps the same was true of the m/e AFTS type although surely not on ALL approaches. I mean if you lose an engine below 300' you're landing whatever happens.
