Our SOP's allow the FO's to do everything, taxiing, engine start,RTO, LOVIS T/O and no limits on landing such as airports and x-wind. But we do have some a/c without dual tillers, in that case we are instructed to full stop on the runway in case of incapacitation even though on the 73 it's absolutely no problem to take a high speed taxiway using only the pedals. But if you've never done it before it can be tricky.
