From what I understand as studied and been told by experts. For the GE90-115b, my operator has a hard EEC program plug derate to 110k, does not matter how many times you click TOGA you get 110k.
Your company restricts max thrust under contract with the engine manufacturer (in some cases for overhaul contracts) or on their own to the thrust allowed by the hard wired program plug on the eec. My previous post to engine out was false. All of your limiting performance data is based on this.
Full rated thrust as a pilot understands is the limited thrust by FADEC, you will get no more as the GE-90-115 is capable of 127k as I hear in the test cell. Rudder authority in an engine out situation would not compensate at 127k and engine wear (overhaul contracts) are based on the hard de-rate setting (more hrs on wing in between)
