This means that, exceptionally, the engine may exceed the EGT redline withoufailure. In this case, the engine continues to deliver its thrust. Consequently, if the flight crew notices an EGT exceedance during the takeoff roll, the flight crew continues the takeoff and establishes the aircraft on the initial climb path, befor

A limited number of small EGT exceedances may be allowed (as Maintenance Manual), but must be reported in the logbook
