Manual setting of T/O thrust does not appear to be a procedure that is trained for or practiced in the simulator.
We need to get all this in perspective. Tiger Moths and Spitfires, Lancasters and Fortresseses and ye olde Boeing 737-200 all had manual "thrust." Surely the requirement to actually train airline pilots how to manually shove open the thrust levers on take off has got to the ridiculous stage. Perhaps the next thing is to have airline pilots undertake an hour in a real flying Cessna 150 with a jumior instructor as part of cyclic training, just to get them out of automation dependancy. Much cheaper than a set of Boeing 777 replacement tyres.
