Xnr,
I dont agree. If I have a donk failure, I am going to pull as much as I need out of the remaining one in order to achieve a safe rate of descent at touch down. If my need is greater than the TQ limit, Temp limit, or N1/NG - then I win and the engine gets torched!! I will pull to the bleed.
This reminds me of a mate who pulled out of a wing over just a tad too low and ripped the skids of a Jet Ranger. He exclaimed: "at least I didnt over torque it". IMHO, stuff the engine, I am trying to save my arse.
I have to agree with rotorque re the CDP. I use it during all twin take offs, very few of which I have Cat A performance, and I even use it for limited power single engine helo work when deciding to go or abort. Besides, you Cat A guys cant have all the groovy words.
