You run yours based on ITT, we run ours based on Torque. We can create engine trends and spot anomolies easier in the engine. By running off of torque we can run a constant ITT, about 765, if it starts to climb on the trend we know to take a look at something. There are different ways to run a turbine.
Yes I'm sure we have one, actually we 2 NGs... My boss likes them.
Posting pics of a PC12 doing 260kts and calling it normal is like a fat chick who only takes pictures looking up to the camera to hide their chin while saying look how skinny I am... You run yours "your way". I run mine "by the book". I've never heard of anyone running the way you do. Nobody teaches running the way you do. I'm sure you have your reason for doing so but don't call it "normal". I get in the low 270's in summer and high 270's in the winter running it "normal"="by the book". Why didn't say in your original picture post that you DON'T run by the book? That post is extremely misleading.

There are 200 King Airs flying for every 1 Pilatus and any crashes in Brazil are hardly worth mentioning.

How about the ones in Mississippi? viewtopic.php?f=41&t=93851As for your statistic, that's wrong too. You should visit Flightaware and search planes "flying by type".

Why do I want a consistent ITT of 765 when I run a consistent ITT of 773? What's the difference? "Per the book", I am taking care of my engine. I'm based at Epps at PDK. Lot's of buddies with PC12's. I fly with a lot of PC12 charter pilots too. Never heard of running the way you do. I don't see anything wrong with it but I wouldn't call it "normal" and post pics of it on the internet.

What book are you referring to? All books associated with the Pilatus are all based on Torque, not ITT...
What I'm saying is we produce a consistent ITT based on setting a torque value. You simply produce an ITT by moving the lever.

A fellow BTer operates 4 KA200s for my current employer. Their department hasn't slurped the PC12 kool-aid quite yet  .[/quote] Many insurance companies and company boards don't like single engines.

Backed up, really, really close to home.

OK, well my board voted PC12. So those cancelled each other out.

Exactly. These threads are no different than when my 10 year old stepson would ask me continuously - What's the best airplane? Given what economics and for what mission son? Always an enjoyable discussion, but never a right answer.[/quote]
What's the best airplane? That's an easy question the one you’re flying right now. The rest is just polite conversation.

Really?
Ok... When I set my Torque, it is based on my current altitude, and temperature. You read the chart that is in the POH or on the cards that you can buy from Pilatus, and it gives you a Torque to set for best power. Every one of those correct calculations should equal about the same ITT. Our NGs are 765. Yours may be lower or higher, but over time it will be a pretty stable number. If we set the Torque and its not the normal temp, then you may need to look at something, usually as simple as a compressor wash or the inert sep.
By simply setting ITT you have no way of determining this information. How do you know if the torque your engine is producing is in line with your ITT? How do you know if this ITT is changing over time? You may not be interested in this information. Our flight department is. Pilatus and Pratt made all of those charts for a reason, not for you to simply set it at 780 and forget it. There is no chart in the entire Pilatus POH that determines power settings from ITT, you can't be ''by the book'' and base it off of ITT.
Im not trying to come across as mean, I like you posts.

I had an engine inspection 450 hours ago when I bought it. I have another due in another 50 so we shall see. According to the torque chart, I can run around above 780.
