For sure, put 300 hp more hp on an aircraft and it always performs better.

Can the rest of us see that data?

That is for Garrett inflight shutdowns and seems to include any number reasons not associated with the core engine. Just in flight shutdown of the engine for any reason. It also include engines run up to 9000 hours before TBO.

It is not data just a comment.

Both of these engines are much more likely to be shut down because a line replaceable unit has failed than because the core engine failed.

Hadn't seen much on the new engine.

Clearly the story on the Denali is going to be the engine. Too bad this didn't enter the market 5 or 10 years ago. Pilatus has already satisfied the bulk of the demand of this market.

Nice Navion. Now that would be a cool testbed for that engine.

There are still lots of King Airs out there. . I think the Denali is a defensive move by Textron to prevent losing overall turbroprop market share.

A short recap of what Paul posted about the engine.

Interesting choice of putting a brand new clean sheet turbine on a single. I like SETP's, but... partly because the engines have a good track record.

As a clean-sheet engine, the ATP may be one of the first engines to utilize extensive additive manufacturing techniques. This approach is so structurally efficient that GE expects 855 conventionally manufactured parts to be reduced to 12 major assemblies, most produced by additive manufacturing techniques. The ATP's launch customer is the Cessna Denali single-engine turboprop that Textron says will fly next year, with certification planned for 2019.

Sounds like they are 3D-printing this engine. That is way cool.

Yeah, I want to be one of the first pilots to fly behind a 3D printed entirely new turboprop on a single engine aircraft.

It wasn't good enough to be a new design, it also had to have an entirely new manufacturing method as well.

It wouldn't surprise me if GE is being teased on this project so Textron can negotiate a lower price on a PT6 at the end. I'd bet my bottom dollar the plane is designed to work with either the GE or the PT6. If GE stumbles, expect a quick change of engines.

I'm sure if Cessna absolutely had to switch last minute they could do it but I doubt very much they are doing twice the engineering at this point to drop either one in. Imagine all the interface work with the G3000, all the structural differences, all the flight testing and other certification tasks. And I don't believe for a second they are using GE to negotiate a better price from PWC so they can pull a bait and switch at the end. First, Cessna already has no doubt a sweet deal being the premier launch customer for GE. Second, Cessna is promoting the crap out of this engine. If they switched at the last minute with no good reason it would look ridiculous.

Might be the only way to make it meaningfully better
