Is this error something specific to the 737 FMC/aircraft or would it cause the same type of thrust error happen in the bigger Boeing's as well. I know that there are some FMC differences as well as significantly different engines.
Tried the same thing twice recently on the 777. One was at a high derate/ATM setting(TO2 assumed 57) and the other was at a heavy weight. In both cases, there was little to no change in the target thrust setting. Perhaps the other Boeing aircraft have a protection feature for this kind of error.
