Exactamundo my friend. On the CV-580, cruise power and takeoff power is set to TIT, turbine inlet temperature. This is always how we set power to match engine temperatures. Horsepower was always close.

One time, we actually were hauling horses in the cargo hold, so we actually had 8,000 hp from the engine, plus 6 horses in the plane, so we had 8,006 horsepower!

Of those 8006, which produced the most pollution?

On the Herc on everyday except the coldest of days ( this was the E model ) we normally set TIT 931 was max power.. 900 was our reduced power takeoff. Our guages were in INCH pounds of torque. and rarely could you pull max torq except on exceptionally cold days. THEN you would match torques. Most of our FE's would match torqs in cruise inboard to inboard and outboard to outboard. Frankly they had free rein most of the time to fine tune the engines for the given situation. In an aircraft which can pull max torq most of the time... setting torqs only makes sense.

Flex, tell him to kindly step out of the drivers seat, clap both hands so you know he isn't touching anything because you just took his turboprop card.

Haha I wish it was that easy! I should call ol' nate dog and tell him. I bet he would have some funny things to say about it!

He could also probably recite some paragraph in some literature directly from Pratt & Whitney that states the proper way to set cruise. He would also tell you the source, page number, and how far down on the left or right page to look.

I cant believe there would be anyone that dumb at your company. Must have slipped through the cracks.

We have a FO in IAH who matches ITT and is looked at like a buffoon

Only one? I can think of several captains that do this too...

Has everyone forgot that every manual (correct me if I'm wrong) references power settings in torque? There is your answer. That's why its called cruise power and not cruise temp. Just ask him where you can find the cruise ITT chart opposed to the cruise power chart in the manual.

Well since you are an FO who knows it is moronic to match ITT's in the Saab I hope you educate those Captains about the systems he is in "command" of.

This guy is gonna freak out if he ever gets to use auto-throttles. He'll be writing it up every time when he notices the A/T won't match up the EGT's, and there's a significant thrust-lever split.

You get what you pay for. F/O's: take the airplane away from this guy long before he gets a chance to kill you, please. Otherwise, you're stuck with the morons.
