[QUOTE=JohnnyDingus;2063021]Well your n1 tolerance gets higher as you go up. So if it's in Togo it would stay at whatever setting it was at for takeoff. I would say an average climb n1 would be 94-95ish once you get throw the upper teens?? Togo is 80's to very low 90's.




Well, you tried. See below.



So yes, N1 will start to increase as altitude increases, even in toga. A higher N1 equals a higher ITT, which will do bad things to an engine. Especially up at a high altitude where there is less air going through the engine to cool it versus a low altitude. Of course you are going to say, "But wait a second! We have a fantastic FADEC system that operates the engine almost automatically! Surely the computer wouldn't let the engine over temp, right?"

Sadly, the answer to that question is no. Once again, see below:



FADEC does not control ITT. Why? I'm not really sure.

So in conclusion, it is very possible that leaving the thrust lever in toga over temped an engine. I do like Biggz & your dismissal that it couldn't of possibly been forgotten because it was on the checklist. Tomorrow I will write the FAA & tell them that they forgot to write "Don't Crash" on the checklist for every airplane I ever flew. Just think of the crashes that could have been prevented if it was only written on the checklist! So....yeah.
