For the T/O phase,when does the time limit start...upon reaching 650C or setting of T/O thrust?And if 650C is not reached during T/O, can the engines be operated at that power setting indefinitely,provided the max continuous limit is adhered to?If possible ,please provide the source of any answers so that I can disseminate the info,or deflect accusations of duff gen!
There is only one correct answer and no sense in shopping answers furthur.
Boeing must answer this and they will of course confirm the answer with the engine manufacturer.
Simply ask your local Boeing rep
