AQIS,
That seems fairly obvious. I do the same. Anyone who is willing to take CR with a 200 hour wonder in the seat needs to get their head examined. This is just one of the many reasons three man Europe is a bad idea. The solo FO gets that crap rest period and is stuck baby sitting during the good rest period, ie his circadian low. If they want three man Europe, make it 2CN/1FO, or at a minimum 1CN/2RQFO. After all, that I'd the "industry standard."
