Is it possible to remove just the assumed temperature part of reduction and continue the take off with de-rates only TO2 or TO1 on 777 or other aircraft type.
On the 744 the only possibility of removing the reduction on take off is with the second push of the TOGA switch but it will remove all de-rates and only after 400 ft AGL (HOLD to THR REF on the FMA) or fire-walling the thrust lever. Maybe deleting the assumed temp part on the thrust limit page on the fmc but the FCOM or my company SOP does not say anything about this procedure.
