I fly a Piaggio. The first place I looked was in the manual, but it just gives you a chart that doesn't tell you what to set your power to or how to set it. EX: at FL350, the ITT should be x and the torque should be y. You could use either value. Common sense tells you to use the most restrictive, but it wasn't black and white. Therefore I didn't reference it in the debate.

Not picking battles, I just think if you are there to do a job according to a manual, for safety or other reasons, why not just to that. Then when the preverbial hits the fan, you were doing it right.

Too many Mavricks doing their own thing cause accidents.

The only real question is, when you come across one, how to handle them?

Stick to SOPs. If you can't, you deserve everything that comes to you.

Its one thing to violate SOP, its another to break the Ca's Ba**s about a 3% difference in charted TQ.

Thats call decision making (Even FO's have to think at times!).

3% is sweets fa, but when you start to see 10-15% or even more over charted, or even between sides is it time to say something?

Nobody is going to bust balls for a needle's width.

I never say anything (as an FO or previously as a CA) unless it is gonna violate or kill me. My captain called me out when I was not matching ITT. It irritates me when my captains tell me how to fly the airplane, and 99% of the time I let it roll off my shoulders even if they are wrong. This was just so silly that I had to respectfully disagree with him. Although in the end I just set the power the way he wanted it so we didn't have to argue. We got along great the entire trip.

I agree with you 100% though. It is better not to knit-pick because then tempers can flare and a breakdown in CRM could result.

I just flew a trip with several different aircraft using PW-120 and PW-123 engines. There was no correlation to higher ITT and higher fuel flow. Sometimes the engine with the higher ITT had a higher fuel flow, sometimes it did not.

Now if his reasoning is that he wants to balance fuel flow, as silly as that sounds, why does he not just match fuel flow gauges?

I have not read all of the posts in this thread, but I just don't understand how someone would think that ITT trumps Torque in power settings. Set your desired torque using ITT as limiting factor. If one engine temps out the hot engine is now your new torque max.... for both engines. By matching ITTs, on most A/C, there is no way that both engines are producing the same amount of torque. This casues the plane to be uncordinated requiring more un-needed rudder trim to be used.
