@his dudeness: No question about the ITT on start, just that I guess I didnt explain myself correctly. The topic of this thread is about the "ITT Fail" indication with engines not running and cold weather, and wether the FADEC would prevent the engines to start when there is an indication missing. This ITT Fail signal comes from the FADEC.
The same thing happened to me, and just the same way you can bring the flaps up without having to start the engines, just pushing start and leaving the throtles on cutoff. We pushed "Start" and on that moment the Fail light extinguished. Wich allows you to continue with the normal start procedure just like TheiC nicely explains.
Pls correct me if I am talking nonsense.
Rgrds,
