But I guess THM's comment:
NOTE The engine is protected against over-TOT and over-torque by a STOP
Was that it implies active TOT management, when in fact it is only Ng that is actively limited. I can recall doing topping checks in a 212 once, where I could not hit the Ng stop before reaching ITT limits. I stopped trying at 10,000 ft!
