What does the statement "this engine is not indicating rated torque for the day"?
Thanks in advance
 
A torque limiter generally has been factory-set for a maximum indicated torque of approximately xx.x PSI (at rotation), sea level – standard day ISA. This setting usually will allow advancing the PCL to the stop with no adverse torque/ITT indications since the engine is not arriving at the rated xx.xPSI.

These factory setting allow for operations throughout most high airfields with no changes to PLC movement except for high/hot ITT considerations.

As long as the torque limiter is functioning correctly, the gearbox will always be protected from exceeding its limits(maximum takeoff). However, as a result,it becomes possible to overtemp the engine due to atmospheric conditions and internal design. Also a possible un-confirmed“downer” is the torque limiter’s effect on the fuel-control unit (FCU) sensing bellows.

I can only assume that the statement you referenced has acknowledged the non standard day or your flying something really old on the turbine side.
