Is someone implying that PW is innovating?

Prove it. Starting one is archaic. You have to look at charts to set power. Honeywell hasn't done much to the TPE but that's only bc it is far ahead of pt-6. Not sure how they improve it outside of adding fadec. It is already 20% more efficient than a pt6.

-14s make a ton of power. A 300 knot pc12 on less fuel plus no ice door so no more piston speeds when you are in clouds is the ultimate turboprop imo

Yup, at 300knts it will make Jets buyers think twice. Just did TEX to PMP, 2000nm in 6.5 hrs...........do that at 300kt with 10-20% less fuel and you can go further and faster.........I was already the same door to door time as a Phenom 300 as they woulda had to stop for fuel.....my lav system now is better and cheaper than ANY jet :D

Well, actually Pratt is innovativing. Attend one of their presentations at your favorite PT6 type convention. Last two I attended they spoke specifically on their FADEC project and reliability improvements among others. Don't get me wrong, some new competition might have lit their fire but they are innovating.

My heartburn with the 331 is reliability. I have yet to see any published engine reliability data from Honeywell. Two likely cases are they don't have it or they don't want to publish it. The PT6A-67 has proven itself in SETPs with many hours and a low failure rate.

I am predicting that Pilatus will respond to the Denali with a more powerful, more efficient, possibly FADEC PT6 engine upgrade.


Yes, I think so too..that is highly probable…and logical...

No doubt about it, was and still is a very good engine…

But I do not see how Honeywell would want to compete now with a new product? Have not heard that they would be in the process of developing one..

and now with GE, and they obviously had to invest tons of money in their new ATP Engine, taking Pratt by the horns, the marketplace could become crowded…

and somehow the new TP Designs like PC12, TBM and now the Denali by way of design lend themselves to the "reverse" concept of a PT6 design or similiar because it is easier to have those two exhaust stacks up front..also makes for a shorter more compact engine...

inertial separators, as cumbersome as they may appear at first sight still are a very effictive way to protect an engine, not only from ice but also from FOD of any sort..( the FOD protection part pretty handy on those TP designs when landing or taking off from unimproved strips or grass..)

and James Raisbeck has proven over and over again, that with a bit of aerodynamic and engineering finesse they can be optimized so as not to rob too much power..

P.S.: I may be wrong, please correct me, but if I remember correctly, Honeywell somehow "lost sight" of the GA market with their TP line, when they concentrated with the 331s in the 70s and 80s on the new commuter airlines and the Metros…

and let us not forget they have been highly successful with their 731 line with the bizjets and their APU programs..so the GA TP side got sort of overlooked..and even if they wanted now, they'd have to come back to the market with a new design..and I doubt that presently at least they are ready to invest what it would take to do that..they have enough other engine programs..for the higher end..

Will there be a twin Denali? A new twin turboprop. GE engines, Garmin panel, a clean sheet design. :popcorn:

Yes. It's called a B200
